10. A mutation in the DNA that produced the strand of messenger RNA shown below produced a newstrand of mutant messenger RNA.UGACUGCAGCUUIf the mutation was a deletion of the first base pair in the second codon, which of the following sequenceswould represent the resulting mutant messenger RNA?A. UACUGCAGCUUB. UGAUGCAGCUUC. UCUGCAGCUUD. UGAGCAGCUU

Respuesta :

mRNA of the mutated DNA: UGACUGCAGCUU (in bold is the second codon)

If the mRNA has a mutation by a deletion on the first base pair of the second codon, the sequence produced will be UGA-UGC-AGC-UU. The second codon is originally CUG but with the deletion, C is left out.

ANSWER: B.
