Which answer choice correctly describes the model of the mRNA strand being transcribed?
Understand the Problem
The question is asking for the correct description of the mRNA strand being transcribed during protein synthesis, specifically how it relates to the DNA template strand and the pairing of nucleotides.
Answer
G
The correct choice is G: The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.
Answer for screen readers
The correct choice is G: The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.
More Information
During transcription, the mRNA strand is formed by matching complementary nucleotides from the DNA template. Uracil (U) replaces thymine (T) and pairs with adenine (A) from the DNA.
Tips
Mistakes include thinking mRNA is an exact copy of DNA and confusing uracil pairing.
