what uses bacteria to copy dna?\na. gel electrophoresis\nb. polymerase chain reaction\nc. nuclear…

Brief Explanations:

Recombinant DNA technology involves inserting foreign DNA into bacteria. Bacteria then replicate, copying the inserted DNA as they divide. Gel electrophoresis separates DNA fragments, polymerase - chain reaction amplifies DNA without using bacteria for replication, and nuclear transfer involves moving a nucleus, not using bacteria to copy DNA.

Answer:

D. Recombinant DNA technology
