DNA consists of two polynucleotide chains, Each chain forms a right-handed spiral with how many bases in one turn of spiral?
- A 4
- B 6
- C 8
- D 10
Answer & Solution
Correct Answer
(D) 10
Step-by-step Solution
Detailed explanation
Watson and Crick proposed that DNA molecule is in the form of a double helix with two polynucleotide chains coiled around one another in a spiral. This is known as B-DNA or biological DNA. It has 10 nucleotides pairs per turn of the double helix and is right handed with a…
