A polypeptide chain is composed of 650 amino adds. What is the minimum number of nucleotides in an mRNA coding for this polypeptide chain Enter your answer as a whole number, (a) (If you think the answer is 1000, then simply enter the number 1000) Below is a partial DNA sequence (the original sequence with no mutations); only the coding strand is shown. Assume the sequence is transcribed and translated from left to right with the reading frame as indicated. 5* = | GGC I GTG I GTA | TTA | GCG I – 3′ The sequence below represents a single mutation In the original sequence above. Mutation #1: 5′ – I GGC I GCG I GTA | TTA | GCG I – 3′ Answer the following questions by filling in the correct term in the appropriate blank provided. (a) This mutant DNA sequence is the result of a __ (a) __, (b) The effect of this base substitution on the amino acid sequence results in a __ (b) __.
