Pretty sure C
A. Doesn’t make sense bc restriction enzymes cleave dna into fragments
B. PCR is used to identify organisms that are difficult to culture

Answer: Plasmid.
A plasmid is a small DNA molecule within a bacteria cell that is separated from the chromosomal DNA and can replicate independently. Through Recombinant DNA, we can insert a gene that we want to see replicated in the plasmid, and when the bacteria multiplies, which it does often, we will obtain a lot of copies of interest gene.
Fatty acids and glycerol best describes the basic structure of lipids. Fatty acids is one of the major components of triglyceride. It is a form of lipids that is used to store energy. Fatty acids are composed largely of a chain carbon atoms bonded with hydrogen atoms. At one of the ends of fatty acids is called carboxyl group. In terms of number of carbons, they are typically an even numbers.
