How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?​
Mama L [17]

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
