Ecori enzyme cuts what sequence
WebProblem Set 5 Answers. 1.a. The frequency of cutting in a random DNA sequence for a given restriction enzyme is once per every 4 n, where n is the number of bases in the restriction enzymes recognition sequence.The “4” derives from the fact that there are four different possible nucleotides that may be inserted at any one position (G, A, T, or C).

Each restriction enzyme moves along a DNA molecule until it … WebQuestion: Restriction endonucleases BamH1, Nhel, BgIII, and EcoRI make sequence-specific cuts in DNA at the following sequences (note that only one strand is shown, but the cut site is a double-stranded palindrome): BamHI: 5'-GGATCC-3' Bg/II: 5-AGATCT-3 Nhel: 5-GCTAGC-3' EcoRI: 5-GAATTC-3 All these enzymes break a phosphodiester bond …
Webphilman on Fri Mar 18 14:31:55 2011 said: Well you can usually calculate it yourself, take the length of the genome, and divide by how often an enzyme cuts on average. For example EcoRI cuts at a 6bp site, the frequency of cutting is 4^6, so it cuts every 4096bp on average, as it's sequnce will occur at random every 4096bp.
