Question

2/19
what is used to cut dna into fragments?
sucrase
restriction enzymes
ligase
polymerase

Explanation:

To determine what cuts DNA into fragments, we analyze each option:

• Sucrase breaks down sucrose, not DNA.
• Restriction enzymes (also called restriction endonucleases) recognize specific DNA sequences and cut the DNA at those sites, producing fragments.
• Ligase joins DNA fragments, not cut them.
• Polymerase synthesizes DNA or RNA, not cut DNA.

Answer:

B. restriction enzymes
