3 0

The answer is A. DNA is the genetic code that eventually gets transcribed into RNA and that RNA is then translated into protein chains (polypeptides). Thus the ultimate purpose of DNA is to build these proteins.

B is wrong because while DNA itself exists in a double helix, its main function is not to build other double helix models. In fact, RNA exists in single helix form.

C is wrong because the brain does not construct the body.

D is wrong because DNA is just a body of information, and not a historical record.

kenny6666 [7]

Confidence votes 3.1K. Sustainable logging means logging an area in such a way as there is always trees to be cut. In other words, logging in a way that leaves young trees, medium age trees and mature trees behind each time you log, so that you can always log that area in the future.
