The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.
Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.
Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.
Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

Answer:
Explanation:In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
The correct answer is (A.) bacteriophages using DNA to infect bacteria.
Explanation
1. In 1952, Alfred Hershey and Martha Chase did experiment to find the genetic material in organisms.
2.Bacteriophages (viruses that affect bacteria) were the key element for Hershey and Chase experiment.
3.In which they concluded DNA as genetic material as bacteriophages use DNA to infect bacteria and not protein.
Pressures can change the state of an environment – e.g. water quality reductions – which then causes impacts such as the loss of biodiversity and ecosystem services provision.
