Molecular Basis Of Inheritance Question 105

Question: 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 [CBSE PMT 2004]

Options:

A) UAUGC

B) UATGC

C) TATGC

D) TCTGG

Show Answer

Answer:

Correct Answer: A

Solution:

Bases sequence in DNA will decide the base sequence in RNA.

Uracil (U) will work as substitute for thymine (T) in mRNA.

Complementary base pairing for mRNA will be $ \begin{aligned} & ATACG \\ & UAUCG \\ \end{aligned} $
