Question

Consider a short segment of a wild-type gene with the following nucleotide-pair sequence: 5-ATG TCC GCA TGG GGA -3 3-TAC AGG CGT ACC CCT -5 Transcription of this gene segment yields the following mRNA nucleotide sequence: 5-AUG UCC GCA UGG GGA-3 and translation of this mRNA produces the amino acid sequence: methionine-serine-alanine-tryptophan-glycine. If a single nucleotide-pair substitution occurs in this gene, changing the G:C at position 7 to A:T, what effect will this mutation have on the polypeptide produced by this gene?
No change
Abnormal protein
Single amino acid substitution
Truncated protein​

Answer 1

Answer:

option 2 is my answer

Explanation:

abnormal changes in aminoacid sequence change
