MRNA Strands That Will Specify Amino Acids in the Protein

Question

mRNA strands that will specify amino acids in the protein gene product are also known as:
A) Coding strands
B) Sense strands
C) Antisense strands
D) Coding strands and Sense strands
E) Coding strands and Antisense strands

Accepted Answer

The mRNA strand that is synthesized from the DNA template strand during transcription is known as the coding strand because it contains the genetic code that specifies the sequence of amino acids in the protein gene product. The mRNA strand has the same nucleotide sequence as the sense strand, which is also referred to as the non-template strand because it is not used as a template for mRNA synthesis. Therefore, the correct answer is D, which includes both the coding and sense strands.
