Q. During transcription, if the nucleotide sequence of the DNA strand that is being coded is ATACG then the nucleotide sequence in the mRNA would be
A) TATGC
B) TCTGG
C) UAUGC
D) UATGC.
Explanation
During transcription RNA synthesis from a DNA template takes place. It involves rewriting of the code without a change in its language. In mRNA, adenine pairs with uracil because thymine is not present in mRNA. So the nucleotide sequence in mRNA would be [image:6_image67.wmf]
