Problem Set on Inheritance and Selection 1. Below is a DNA sequence from the middle of a gene: 5’ G T C A A A A A T G G C T A G C T A G A 3’ 3’ C A G T T T T T A C C G A T C G A T C T 5’ a. How many possible ways in theory are there to translate this sequence? Hint: a codon consists of three nucleotides. six ways; three from the top strand, and three from the bottom strand depending upon how the bases are grouped by threes. b. Take a critical second look at the sequence above. Which of the possible amino acid sequences from question 1a is actually encoded here? Write the encoded amino acid sequence from NH 2 end to COOH end. Hint: Use the code table and try out some possible sequences. There is only one correct answer. After trying all possible 6 sequences, notice that all but one have a stop codon. Since this is the middle of a sequence, there should be no stop codons. The correct answer below is from copying the bottom strand in this fashion: DNA: 3’ GTT TTT ACC GAT CGA TCT 5’
