In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
A
convert the DNA into gel
B
cut the DNA into fragments
C
change the color of the DNA
D
produce longer sections of DNA
Explanation: 

Detailed explanation-1: -QUESTION 7 preparation for an electrophoresis procedure, enzymes are added to DNA in order 0 A convert the DNA into gel change the color of the DNA ccut the DNA into fragments Dproduce longer sections of DNA.

Detailed explanation-2: -In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into smaller fragments. The cuts are always made at specific nucleotide sequences.

Detailed explanation-3: -Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences.

Detailed explanation-4: -Each restriction enzyme moves along a DNA molecule until it finds a specific recognition sequence in the DNA. The enzyme cuts the double-stranded DNA, resulting in DNA fragments.

Detailed explanation-5: -In cells and in the lab, enzymes called ligases are used to join fragments of DNA together.
