Answer:

1.

C. Has less than 10 bp per turn of its helix.

2.

D.) 15

Explanation:

Negatively supercoiled DNA

(deoxyribonucliec acid) is the twisting against the helical conformation which is a twist in a left handed direction that loose and straightens the helix at low twisting stress, and knot the DNA into negative supercoils at high twisting stress.

Supercoiling will occur where the DNA helix must uncoiled for the function of a macromolecular assembly.

Supercoiling allows DNA to be packed into small spaces, It allows for more negative charge and can be found in many cells. But it does not have less than 10 bp per turn of its helix.

15 rotations will correspond positively supercoiled dna molecule of 100base pair.

How is muscle color related to muscle specialization?
kati45 [8]
<span>Muscle color is related to muscle specialization because it indicates whether muscles are used more for aerobic or anaerobic metabolism. Aerobically respiring muscles that do work over a long period of time have more red oxidative fibers, while anaerobically respiring muscles that do work in bursts have more white glycolitic fibers.</span>
