After a polypeptide is produced in protein synthesis, it\'s not necessarily a functional protein yet! Explore protein folding that occurs within levels of protein structure with the Amoeba Sisters! Primary, secondary, tertiary, and quaternary protein structure levels are briefly discussed. Video also mentions chaperonins (chaperone proteins) and how proteins can be denatured.
This Amoeba Sisters video starts with providing examples of prokaryotes and eukaryotes before comparing and contrasting prokaryotic cells with eukaryotic cells! Free handout at https://www.amoebasisters.com/handouts. More detail about cell structure and organelles can be found in our cells video: https://youtu.be/8IlzKri08kk
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.
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! Vocabulary in this video includes chromosome, chromatid, haploid, diploid, crossing over, and homologous chromosomes.
What happens when you can\'t do aerobic cellular respiration because oxygen isn\'t available? Explore fermentation with The Amoeba Sisters! This video focuses on alcoholic fermentation and lactic acid fermentation, and it also mentions how this pathway is different from anaerobic cellular respiration.
Explore chromosomes and karyotypes with the Amoeba Sisters! This video explains chromosome structure, how chromosomes are counted, why chromosomes are important, and how they can be arranged in a karyotype! This video also tackles a few misconceptions about how chromosomes.
Explore the parts of the cell membrane with The Amoeba Sisters! Video discusses phospholipid bilayer, cholesterol, peripheral proteins, integral proteins, glycoproteins, and glycolipids - as well as why the surface area to volume ratio is so important in cells.
Join the Amoeba Sisters as they discuss the terms \"gene\" and \"allele\" in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity. Note: as mentioned throughout video, the ability to taste PTC may be more complex than a single gene trait. This video serves as an introduction before exploring Punnett squares in our heredity series: https://www.youtube.com/watch?v=fcGDU...
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
Explore DNA structure/function, chromosomes, genes, and traits and how this relates to heredity! Video can replace old DNA structure & function video and in addition covers foundational concepts of heredity.
Explore several ecological relationships with The Amoeba Sisters! Ecological relationships discussed include predation, competition, and symbiotic relationships (parasitism, mutualism, and commensalism).
Explore cell signaling with the Amoeba Sisters! This introductory video describes vocabulary such as ligand and receptor. It includes the stages of cell signaling (reception, transduction, and response) and different types of signaling including autocrine, paracrine, and endocrine. This is just an introduction to a series on signaling that we hope to expand on in the future!
Explore homeostasis with the Amoeba Sisters and learn how homeostasis relates to feedback in the human body. This video gives examples of negative feedback (temperature and blood glucose regulation) and positive feedback (events in childbirth).
This Amoeba Sisters video introduces science lab safety guidelines. This video includes the discussion of proper lab attire, importance of proper disposal of materials, precautions when heating substances, and the importance of the MSDS (pinned comment note: this term has actually been replaced with SDS). As mentioned throughout the video, these are only general safety guidelines and there are many more that may be applicable to specific labs- always read specific lab guidelines.
Discover what happens when random events meet allele frequencies: genetic drift! This Amoeba Sisters video also discusses the bottleneck and founder effect as well as contrasts genetic drift with natural selection.
Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why classification can have major changes due to DNA and cell structure evidence.
The word \"theory\" is used very differently in casual everyday life vs. in science. In science, the word \"theory\" means so much more! Learn about what a scientific theory is with The Amoeba Sisters and discover why a scientific theory will never graduate into a scientific law.
Explore the basics of how antibiotics, antivirals, and vaccines work to help your immune system in the fight against pathogens! This Amoeba Sisters video also briefly introduces the lines of defense in the immune system and discusses how vaccines can be important for \"herd immunity.\"
Let the Amoeba Sisters introduce you to bacteria! This video explains bacterial structure, reproduction, and how not all bacteria are \"bad!\" Video also briefly mentions endospores, plasmids, and bacteria transformation.
Get introduced to protists and fungi with the Amoeba Sisters! This video explores basic cell type, mode of feeding, habitat examples, and ecology of both protists and fungi. This video also mentions a few examples of how protists and fungi can be useful- and harmful- to humans.
