How is DNA copied?
Sedaia [141]

Answer:

The DNA is copied by B: The sense strand of DNA is used as a template to create both strands of the new double helix.

Explanation:

Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.

During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template.  The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.
