Q. One strand of DNA has sequence of nucleotide 3’ ATTCGCTAT 5’ then other strand of DNA has
A) 3’ TAAGCGATA 5’
B) 5’ TAGCACGTA 5’
C) 5’ TAGCACGTA 3’
D) 5’ TAAGCGATA 3’
Explanation
In a double stranded DNA, the sequence of nucleotides is complementary to each other, $i.e$., A pair with T and G pair with C. So, the sequence of nucleotide for 3’ ATTCGCTAT 5’ will be 5’ TAAGCGATA 3’.
