Restriction Dna Strands Fragments Cut Intact Explain Role

Restriction endonucleases are enzymes that cut DNA into fragments at specific sites, leaving satellite regions intact. This results in a mixture of fragments containing intact mini/microsatellite regions for DNA profiling.

Les endonucléases de restriction sont des enzymes qui coupent l'ADN en fragments à des sites spécifiques, laissant intactes les régions satellites. Cela permet de créer un mélange de fragments contenant des régions mini/microsatellites intactes pour le profilage de l'ADN.

Front Explain the role of restriction endonucleases in DNA profiling.
Back Restriction endonucleases:
  • Enzymes that cut strands of DNA into small fragments
  • They only cut at specific nucleotide sequences - restriction sites
  • They cut DNA strands at defined points in introns, leaving satellites intact so fragments at end of the process include mixture of intact mini/microsatellite regions
