MasteringGenetics Psi x 4 Da https://session mast PCB30 63 assignmentProblee l e a Search Genetics Amino acid permutations dy Amino acid permutations Part A Hydroxylation of lysine and proline yields hydroxylysine and hydroxyproline. These modified amino acids (AA) maintain the strength and structure of collagen. Abert is working in the research and has been tasked to develop a short synthetic protein 20 AAlong from scratch. He has the frst 17 amino acids of the protein, but is unsure of the remainder of sequence. Knowing that lysine and proline is possible under his set conditions, how many different protein the es of the appropriate length can be synthesized using Albert's 17AA starting block Submit My Answers Give Up Continue a WI re to searchExplanation / Answer
The amino acid sequence already has 17 amino acids. There are three positions that are available to be occupied by only two amino acids - hydroxyproline or hydroxylysine . Since, only 3 places are allowed for adding the amino acids, the answer will be 3P2 .
= 3! / (3-2)!
= 6
Therefore, 6 different amino acid sequences can be synthesised using the given 17 AA block.
