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
DNA Strand
One of the two long chains of nucleotides that form the double helix structure of DNA, carrying genetic information.
mRNA
Messenger RNA, a type of RNA that conveys genetic information from DNA to the ribosome, where it specifies the amino acid sequence of the protein products.
Amino Acid Sequences
The order of amino acids in a protein, which determines the protein's structure, function, and properties.
- Explain the mechanics behind transcription and translation, elucidating the functions of mRNA, tRNA, and rRNA within this context.
- Recognize the ubiquitous nature of the genetic code among diverse species.

Final Answer :
B
Explanation :
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.
