Homework Answers
Question 13 - There are 20 different types of amino acids.
Question 14 - A tRNA or transfer RNA helps to translate the message received by mRNA into a specific amino acid. Since there are 20 different amino acids, there are 20 different functional types of tRNA corresponding to each amino acid.
Question 15 - Valine is the amino acid which replaces the sixth amino acid, glutamic acid in the chain. So patients with Sickle Cell Anemia have Valine.

Which sequence of amino acids, if any, would you predict to find in the interior of chymotrypsin (not the active site)? A. threonine, arginine, tyrosine B. glutamic acid, isoleucine, lysine C. valine, tryptophan, glycine D. None of the above. The answer is C, please explain why? Is it because those are hydrophobic amino acids?

There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein. During protein synthesis, the job of a tRNA molecule is to carry its particular amino acid to the growing protein chain and find the correct amino acid position there. It does this by matching a 3- letter anticodon on the tRNA to a complementary 3-letter codon on mRNA. Below, in a diagram of a ERNA molecule, nucleotides are represented by small circles, some...
