Restriction Enzymes Have Proved So Useful in Manipulating DNA Because

Question

Restriction enzymes have proved so useful in manipulating DNA because
A) they cut at defined sites AND the sticky ends make it very easy to allow recombination of DNA with RNA.
B) they cut at random sites AND the sticky ends make it very easy to allow recombination of any type of DNA.
C) they cut at defined sites AND the sticky ends make it very easy to allow recombination of any type of DNA.
D) they protect eukaryotes against virus attack AND they cut both RNA and DNA.
E) they protect eukaryotes against virus attack AND the sticky ends make it very easy to allow recombination of DNA with RNA.

Accepted Answer

Restriction enzymes cut at specific recognition sites, which can be predetermined and chosen to target specific regions of DNA. Additionally, the sticky ends produced by the enzyme make it easy to recombine the cut DNA with other DNA fragments, allowing for easy manipulation of genetic material. The other answer choices contain incorrect information.
