Protein synthesis is the process by which cells build proteins. It involves two main stages: transcription and translation. In transcription, the DNA code is copied into a molecule called RNA. In translation, the RNA code is used to build a protein. The Amoeba Sisters have created a video recap of protein synthesis, which is a great resource for students who are learning about this topic.
The Amoeba Sisters
The Amoeba Sisters are two sisters, Brianna and Sarina, who create educational videos about science. They started making videos in 2013 and have since become popular on YouTube. Their videos are known for being engaging and easy to understand.
The Amoeba Sisters have created a video recap of protein synthesis, which is a great resource for students who are learning about this topic. The video is about 12 minutes long and covers the key concepts of protein synthesis.
Transcription
In transcription, the DNA code is copied into a molecule called RNA. This process occurs in the nucleus of the cell. The RNA molecule is made up of nucleotides, which are similar to the nucleotides in DNA. However, RNA contains the nucleotide uracil instead of thymine, which is found in DNA.
There are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries the genetic code from DNA to the ribosome, where protein synthesis occurs. tRNA carries amino acids to the ribosome, where they are used to build proteins. rRNA is a component of the ribosome.
Translation
In translation, the RNA code is used to build a protein. This process occurs in the ribosome, which is a complex structure made up of proteins and rRNA. The ribosome reads the mRNA code and uses it to assemble a chain of amino acids.
Each amino acid is specified by a sequence of three nucleotides, called a codon. There are 64 possible codons, but only 20 amino acids, so some amino acids are specified by multiple codons. The ribosome reads the mRNA sequence one codon at a time and adds the corresponding amino acid to the growing chain.
Protein Synthesis Recap
The Amoeba Sisters’ video recap of protein synthesis covers both transcription and translation in detail. They explain each step of the process and provide examples to help students understand the concepts.
The video begins by explaining the structure of DNA and RNA. It then moves on to transcription, where the DNA code is copied into RNA. The video explains the three types of RNA and their functions.
Next, the video covers translation, where the RNA code is used to build a protein. The video explains how the ribosome reads the mRNA code and assembles a chain of amino acids. It also explains the role of tRNA in bringing amino acids to the ribosome.
The video ends by summarizing the key concepts of protein synthesis and providing a few practice problems for students to test their understanding.
Updated Answer Key
The Amoeba Sisters recently updated their answer key for their protein synthesis video recap. The answer key provides detailed explanations of the practice problems that are included in the video.
The updated answer key includes more detailed explanations and additional examples to help students understand the concepts. It also includes a section on common misconceptions and how to avoid them.
Conclusion
The Amoeba Sisters’ video recap of protein synthesis and their updated answer key are both great resources for students who are learning about this topic. The video is engaging and easy to understand, and the answer key provides detailed explanations of the practice problems.
Overall, the Amoeba Sisters are a great resource for students who are interested in science. Their videos are informative and fun, and they make complex topics easy to understand.
