Question

What are restriction enzymes? what are restriction enzymes? exonucleases that degrade single-stranded dna endonucleases that randomly cut dna at nonspecific sequences exonucleases that degrade double-stranded dna endonucleases that cut double-stranded dna at a precise nucleotide sequence (typically 4-6 nucleotides?

Answer 1

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme "scans" a DNA molecule, looking for a particular sequence, usually of four to six nucleotides.
