Biology 202 NAME: Fall 2007 T.A.: Homework 3 Discussion Section #: Due: September 13 or 14 1. A tRNA molecule carries the anticodon 3’ AUG 5’. (2 pts) a. Identify the mRNA codon that binds to this anticodon. 5’ UAC 3’ b. Identify the amino acid that would complex with this tRNA molecule. Tyrosine c. Because of wobble, this anticodon may be able to match up with additional codons. Identify the additional codons and the amino acids specified. G in the 5’ end of anticodon can pair with either C or U. Both UAC and UAU encode tyrosine. 2. During post-transcriptional mRNA processing, a mature mRNA was created that mistakenly included an intron sequence. (2 pts) a. Describe two different effects this could have on the resulting protein. Two effects of retention of an intron are 1) alteration of the reading frame (causing a frameshift) so that incorrect amino acids are incorporated into the protein from the start of the intron forward or 2) if the reading frame is not altered, the protein will contain a
