Why is only one strand of DNA transcribed into mRNA?
A) Because mRNA is only required in small quantities
B) Because transcribing both DNA strands would produce different amino acid sequences
C) Because the other strand would produce the same amino acid sequence in reverse order
D) Because all genes are located on the same DNA strand, while the other strand acts as protection
E) Because the other strand is transcribed directly into amino acids

Question

Quizplus · Accepted Answer

Transcribing both strands of DNA would result in mRNA sequences that code for different amino acid sequences, as each strand of DNA has a different nucleotide sequence. This could lead to the production of different, potentially non-functional or harmful proteins.
