Restriction endonucleases do which of the following?
A) cleave DNA at very specific locations based on the sequence of bases
B) limit which bases can be at the ends of a strand of DNA
C) remove specific codons DNA
D) remove specific exons from DNA

Question

Quizplus · Accepted Answer

Restriction endonucleases are enzymes that recognize specific DNA sequences and cleave the DNA at those locations. These sequences are usually palindromic, meaning the sequence reads the same forward and backward. This allows restriction endonucleases to identify and cut DNA at very specific locations, which is useful in a variety of applications, such as gene editing or cloning. Choices B, C, and D are not accurate descriptions of what restriction endonucleases do.
