Question 6

Restriction enzymes cuts DNA at a specific ___ of nucleotides.

a. promoter regions

b. sequence

c. plasmid nucleotides

d. AUG codon

The correct answer is: sequence.

Explanation:

Restriction enzymes are proteins found in bacteria that cut the DNA into fragments to form molecules called "rectriction sites". These restriction sites are used in molecular biology to identify polymorphisms (variations in the DNA fragment sequence).

These restriction sites are specific DNA sequences that are often palindromic (meaning that the strand is read the same from whichever direction).
