Question

In a molecule of DNA, the complementary sequence for 5' AATTCGCTTA 3' is

A) 5' AATTOGCTTA 3'
B) 3' AATTCGCTTA 5'
C) 5' TAACGCTTAA 3'
D) 3' TTAAGCGAAT 5'
E) 3' TAAGCGAATT 5'

Answer 1

3' TTAAGCGAAT 5'

Step-by-step explanation:

DNA is present as genetic material in all the living organism except some viruses. The DNA is present as a linear double stranded molecule in case of eukaryotes.

The nitrogenous bases present in DNA shows complementary nature. Adenine binds with thymine containing two hydrogen bonds whereas cytosine binds with thymine with three hydrogen bonds. DNA strands are anti parallel in nature.

Thus, the correct answer is option (D).
