A portion of a polypeptide produced by a mammalian cell was found to have the following sequence of amino acids:...Lys-Ser-Pro-Ser-Leu-Asn-Ala... - In a normal cell...Lys-Val-His-His-Leu-Met-Ala...- In a mutant cella.) What was the nucleotide sequence of the mRNA segment that encoded this portion of the original polypeptide?b.) What was the nucleotide sequence of the mRNA encoding this portion of the mutant polypeptide?c.) Can you determine which nucleotide was deleted and which was inserted?
