Role of DNA in Protein Synthesis - Learn Online at CCC
The sequence of the nucleotides in DNA can be referred to as the genetic code.Each portion of the nucleotide sequence in DNA that is responsible for the length andsequence of amino acids in one particular protein can be called a gene.Our DNA seems to be ultimately responsible for the size, shape and function of everyprotein that our bodies make. Similarly, the DNA of each plant and animal seems to beultimately responsible for the size, shape and function of every protein that each of themmakes.
Gene Function: Protein Synthesis Flashcards | Quizlet

Protein synthesis, the process of genes contributing to a phenotype, is complex and can be difficult for students to learn. Watching their teacher demonstrate their understanding of it while they teach is not enough for the students to truly understand what is going on at the cellular and molecular levels. They need to practice using these ideas, making mistakes and learning from them, in an environment with some support, before they are expected to use these concepts on their own when encountering new phenomena. This is a great activity to allow students to do just that as they work with a model of protein synthesis that involves their entire classroom. The teacher's desk is the nucleus containing the DNA sequences. In teams of 3, student 1 becomes the mRNA when they transcribe the DNA in nucleus and return to student 2, the ribosome. The ribosome (student 2) writes out the needed tRNA sequence to match the mRNA. Student 3, tRNA, looks for the correct sequence in the cytoplasm (classroom) and when they find it they flip up the card to reveal a word (amino acid). They return to the ribosome with their word (amino acid) to build a sentence (protein). The number of sentences you have your students work through would depend on when it takes them to get comfortable with this process before they move on to examine different types of mutations.

After identifying the reading frame in a DNA sequence, you determine the amino acid sequence and then try to create each of the mutations described at this website. Notice the impact each mutation has on the protein product and imagine the impact it could have on the phenotype for that trait. This is an event that results in genetic variation for that trait. Not all mutations will have the same impact on the trait and its phenotype. Developed by The Genetic Science Learning Center at the University of Utah. ( - AAAS Benchmarks and - )
