Restriction Endonucleases Or Restriction Enzymes. What Are Restriction Enzymes. They are enzymes that act as molecular scissors because they are able to cut DNA at specific base pairs. Each restriction enzyme recognizes a characteristic sequence of nucleotides, this is the recognition site.
Restriction Enzymes. Restriction Endonucleases. Also called restriction enzymes 1962: “molecular scissors” discovered in in bacteria E. coli bacteria have an enzymatic immune system that recognizes and destroys foreign DNA
Restriction Enzymes. Presented by: Elizabeth Gordon April 11,2006. Function. (From Tock and Dryden 2005). Historical Perspective. (From Lewin 2003). Four Types. (From Tock and Dryden 2005). Type I. Three subunits form R 2 M 2 S 1
Restriction Enzymes. Restriction Enzymes scan the DNA sequence Find a very specific set of nucleotides Make a specific cut. Palindromes in DNA sequences.
Restriction Enzymes. Discovery. In 1962, Werner Arber, a Swiss biochemist, provided the first evidence for the existence of "molecular scissors" that could cut DNA.
Restriction Enzymes. Molecular Scissors. Restriction enzymes are molecular scissors. Restriction Enzymes scan the DNA code Find a very specific set of nucleotides Make a specific cut. Picking a palindrome Words that read the same forwards as backwards. Hannah Level Madam. hannaH leveL
Restriction Enzymes. Aims: Must be able to recall the basic functions of restriction enzymes. Should be able to outline how specific restriction enzymes work. Could be able to explain the different ends produced by restriction enzymes and their benefits. Restriction Enzymes.
