B)6
C)7
D)8

Question

Quizplus · Accepted Answer

The DNA sequence can be converted into mRNA by replacing thymine (T) with uracil (U) and reading from 5' to 3'. Therefore, the mRNA sequence would be 3' UACGGACUUAGUCGAAAU 5'. Using the genetic code, we can then determine that this mRNA sequence codes for 6 amino acids (Met-Pro-Asn-Gln-Leu).
