Question

A section of DNA is transcribed to produce a strand of mRNA. The original DNA has the following sequence of nitrogen bases: ATG GCC CAA TCG TGA Due to a point mutation, transcription results in the mRNA sequence of: UAC CGG GUU AGU ACU Transcription in this case will result in
A)a mutated protein that is potentially harmful.
B) the correct sequence of amino acids in the synthesized protein.
C) a situation where protein synthesis does not "stop" translating.
D) the incorrect sequence of amino acids in the synthesized protein.

Answer 1

the answer is  B  the correct sequence of amino acids in the synthesized protein.

Answer 2

Answer:

B) the correct sequence of amino acids in the synthesized protein.

Explanation:

The given DNA sequence is ATG GCC CAA TCG TGA. Its corresponding mRNA sequence would be UAC CGG GUU AGC ACU.

However, the point mutation has replaced the "C" from forth codon and the mutated codon is "AGU".

Both AGC and AGU code for amino acid "Serine". So, there would not be any change in the amino acid sequence encoded by mRNA which is transcribed from mutated DNA.
