Mitosis vs. Meiosis: Side by Side Comparison
 
06:22
After learning about mitosis and meiosis from our individual videos, explore the stages side by side in this split screen video by The Amoeba Sisters! Expand video details for table of contents. Vocabulary in this video includes chromosome, chromatid, haploid, diploid, crossing over, and homologous chromosomes. Contents: 0:50 Intro to Mitosis/Meiosis 1:07 Starting Cells in Mitosis/Meiosis 1:20 Interphase (happens before mitosis and meiosis) 2:19 Mitosis/Meiosis I Split Screen 4:30 End of Mitosis 4:46 Meiosis II Hope you enjoy our comparison! You can see our individual videos on mitosis https://youtu.be/f-ldPgEfAHI and meiosis https://youtu.be/VzDMG7ke69g We also like to pin extra points/clarifications here. Crossing over in meiosis has a major role in genetically diverse offspring; however, Pinky learned in one of her graduate courses that mitosis crossing over- while very rare (likely why it's uncommon to see it in intro bio courses)- can occur. It can have a role in human cancer and "loss of heterozygosity." While this unusual event is not discussed in this intro video, here is a further reading suggestion where you can learn more about it: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648873/ . P.S.

Protein Synthesis (Updated)
 
08:47
Explore the steps of transcription and translation in protein synthesis! This video explains several reasons why proteins are so important before explaining the roles of mRNA, rRNA, and tRNA in the steps of protein synthesis! Expand details for contents and resources. 👇Video handouts and resources on http://www.amoebasisters.com/handouts. This video replaces our old protein synthesis video: https://youtu.be/h5mJbP23Buo Table of Contents: 0:46 Why are proteins important? 1:48 Introduction to RNA 2:22 Steps of Protein Synthesis 2:43 Transcription 3:54 Translation 6:08 Introduction to mRNA Codon Chart 7:51 Quick Summary Image Vocabulary in this video includes DNA, mRNA, rRNA, and tRNA. This video mentions that proteins can be made of 1 or more polypeptide chains and that proteins typically experience folding and other modifications (to be functional proteins.) Codons and the amino acids they code for is represented by standard charts can be found in the public domain. While the rectangle chart is the common format, there may be other ways to represent the information. P.S. If learning about mutations, check out this cool codon chart that includes mutations(!!) in the public domain: https://commons.wikimedia.org/wiki/File:Notable_mutations.svg Our videos are designed to introduce basic concepts and hopefully to inspire students to stay curious about the content. We simply cannot include all of the exceptions and minute details in a video under 10 minutes, and this is why we so frequently remind people of this in our videos. We want students to go beyond our videos to explore the depth of the material. P.S. On our website, we emphasize that our videos contain science comics- not scientific illustrations.

Mitosis: The Amazing Cell Process that Uses Division to Multiply! (Updated)
 
08:27
Updated Mitosis Video. The Amoeba Sisters walk you through the reason for mitosis with mnemonics for prophase, metaphase, anaphase, and telophase. Expand details to see table of contents.👇 Video handout here: http://www.amoebasisters.com/handouts Table of Contents: Why is Mitosis Important? 0:44 Why Don't You Want Cells Dividing all the Time? 2:00 Interphase (occurs before mitosis) 2:23 DNA and Chromosomes 2:55 Chromosome Replication 4:07 PMAT Mitosis Stages 5:30 Cytokinesis (actual splitting of cell) 7:30 We appreciate the feedback we get for what we need to clarify or should have added. Here is a clarification (also pinned in comments): (1) We mention mitosis as "a type of cell division." To be specific, it's a division happening within the cell - in the nucleus. But we do not introduce the nucleus until later on in video. Mitosis is specifically the division happening of the nucleus whereas cytokinesis follows to do the actual splitting of the cell (mentioned at 7:30). (2) Our video is intended to focus on animal cells (as drawn) - specifically human cells - as we use human chromosome numbers. We wish we had clarified that more as we appreciate the feedback that the statements, "Mitosis makes body cells. Meiosis makes gametes." has some big exceptions such as plants. (3) In metaphase, we do not draw a nucleus (6:09), because we mention it already has been disassembled. Disassembly of the nuclear membrane (envelope) occurs at the end of the previous stage. Many texts will state this is during prometaphase, a stage in between prophase and metaphase. In this short video, we do not include prometaphase. We only mention that the nucleus is no longer there by the time it's metaphase. (4) Notice our illustration in anaphase also includes a text box that says "sister chromatids separate" at 6:37. It's important to understand that chromosomes are moved "away" in anaphase, but as the text box notes, realize they are separated by the pulling apart of sister chromatids. This is especially important when comparing mitosis to meiosis I---as you can see our comparison video (which has more detail) here: https://youtu.be/zrKdz93WlVk Support us on Patreon! http://www.patreon.com/amoebasisters Our FREE resources: GIFs: http://www.amoebasisters.com/gifs.html Handouts: http://www.amoebasisters.com/handouts.html Comics: http://www.amoebasisters.com/parameciumparlorcomics Connect with us!

Cellular Respiration and the Mighty Mitochondria

Explore how ATP is made in 3 steps of aerobic cellular respiration with the Amoeba Sisters! This also compares this process to photosynthesis and introduces ATP structure. This video has a handout here: http://www.amoebasisters.com/handouts.html We appreciate feedback on our videos and pin clarifications on our videos if needed. We do wish we had been more clear stating that the Krebs cycle "'indirectly" requires oxygen" instead of just stating it "requires oxygen" ---as we do not want to imply that oxygen is a reactant in the Krebs cycle (Citric Acid Cycle). While oxygen is not a reactant for the Krebs Cycle, the oxidation steps of the Krebs Cycle cannot occur without the presence of oxygen. (Thus, the Krebs Cycle is considered an aerobic process) Reference Source: OpenStax https://cnx.org/contents/[email protected]:[email protected]/Oxidation-of-Pyruvate-and-the- 36 ATP? 38 ATP? The big thing we want to emphasize, as we do in the video, is this number is an estimate. It's likely not even as high as those numbers everytime. And regarding the video note about how ATP may need to be used to shuttle in NADH from glycolysis---here's a question answered by Miller and Levine that you may find helpful: http://www.millerandlevine.com/ques/atp.html Support us on Patreon! http://www.patreon.com/amoebasisters Our FREE resources: GIFs: http://www.amoebasisters.com/gifs.html Handouts: http://www.amoebasisters.com/handouts.html Comics: http://www.amoebasisters.com/parameciumparlorcomics Connect with us!

This is due to the fact that their building blocks are made of two different substances (glycerol and fatty acids) that attach to each other--rather than attaching as one type of monomer to another.

Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video has a handout here: http://www.amoebasisters.com/handouts.html This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out though that when it comes to biological sex- it can be influenced by more than just sex chromosomes X and Y. For example, the SRY gene, plays a major role in human biological sex determination. While this video only focuses on solving sex-linked trait problems in a Punnett square, here are some further reading suggestions to learn about the SRY gene and its role in biological sex.

Mutations: The Potential Power of a Small Change
 
07:22
The Amoeba Sisters discuss gene and chromosome mutations and explore the significance of these changes. Music used with permission from Adrian Holovaty (http://www.youtube.com/adrianholovaty). This video has a handout here: http://www.amoebasisters.com/handouts.html We appreciate the feedback we get for clarification or improvements on our videos. At 2:11, we try make the A (adenine) base look upset now that the complementary base T (thymine) has been replaced with a G (guanine) in a point mutation. But we wish we had put more distance between the cartoon bases to clarify, that now, they cannot bond in this way.

Osmosis and Water Potential (Updated)
 
09:57
Explore the process of osmosis in this updated Amoeba Sisters video! Video features real life examples of osmosis, important vocab, and introduces concept of water potential and turgor pressure in plant cells. Expand details for table of contents. We have an Unlectured resource on this topic! https://www.amoebasisters.com/unlectured Contents: 0:59 Osmosis Definition 4:20 Osmosis in Animal Cells Example 7:00 Osmosis in Plant Cells Example 7:30 Water Potential 9:22 Create Something Prompt! We are so appreciative of feedback we receive as it helps us continue to improve. In this video, we say the word "molecules" several times. Chemically speaking---the term "molecule" may be ok when referring to water but not salt as we did in 2:54. Salt is formed by ionic bonds [not molecular (covalent) bonds like you would see in water]. Vocabulary includes solute, solvent, passive transport, hypertonic, hypotonic, isotonic, equilibrium, water potential, pressure potential, turgor pressure, and solute potential. NOTE: We defined water potential as potential energy in water (supported in reference: https://cnx.org/contents/[email protected]:[email protected]/Transport-of-Water-and-Solutes), but in the video, we do note that this definition can be expanded upon or worded in many different ways. In bio specifically, water potential tends to be used to describe where water travels based on solute potential and pressure potential.

As the note mentions, some vaccines require "booster" doses. *Further Reading Suggestions:* -Importance of Vaccinations from CDC: https://www.cdc.gov/vaccines/vac-gen/howvpd.htm -What if we stopped vaccinating? from CDC https://www.cdc.gov/vaccines/vac-gen/whatifstop.htm -https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4024226/ -https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4203350/ -https://www.ncbi.nlm.nih.gov/pubmed/24814559 -Learn more about Herd Immunity here: https://www.pbs.org/wgbh/nova/article/herd-immunity/ -Learn more about myths and facts regarding vaccines: https://www.texaschildrens.org/departments/center-vaccine-awareness-and-research-cvar/vaccine-facts-and-myths#Myth:%20A%20preservative%20used%20in%20vaccines%20causes%20autism Support us on Patreon! http://www.patreon.com/amoebasisters More ways to Support Us? http://www.amoebasisters.com/support-us.html Our Resources: Biology Playlist: https://www.youtube.com/playlist?list=PLwL0Myd7Dk1F0iQPGrjehze3eDpco1eVz GIFs: http://www.amoebasisters.com/gifs.html Handouts: http://www.amoebasisters.com/handouts.html Comics: http://www.amoebasisters.com/parameciumparlorcomics Unlectured Series: https://www.amoebasisters.com/unlectured Connect with us!
