WebIf the enzyme cut the plasmid into two roughly equal sized pieces, those pieces would run about the same, and would likely be indistinguishable on a gel. This is further supported by the information about this experiment which states that roughly equal amounts of DNA were loaded into Lanes 1-4. WebMay 14, 2024 · 5.7: Restriction Enzymes. Restriction enzymes are DNA-cutting enzymes found in bacteria (and harvested from them for use). Because they cut within the molecule, they are often called restriction endonucleases. To be able to sequence DNA, it is first necessary to cut it into smaller fragments. Many DNA-digesting enzymes (like … chicle sandiaWebNov 20, 2007 · In the labs, restriction enzymes (or restriction endonucleases) are used to gash DNA into smaller bits. The cuts are always made at specific nucleotide sequences. … chickris md

"WebThe discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragments at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends.
