10
AnswerD.
12
Answer: Option C
Solution
Answer: Option C
Solution:
The number of bases in the single turn of the DNA helix is 10.DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. DNA is a long polymer made from repeating units called nucleotides, each of which is usually symbolized by a single letter: either A, T, C, or G.
DNA can be twisted like a rope in a process called DNA supercoiling. With DNA in its "relaxed" state, a strand usually circles the axis of the double helix once every 10 base pairs.
