WebRestriction enzymes that cut within the multiple cloning site (MCS) and result in a diagnostic pattern of 2-5 easy to resolve bands are typically selected. Methylation sensitivity of selected enzyme (s) should also be considered to assure that methylation from the host organism, such as dam, dcm, or CpG methylation, does not block cleavage. WebRestriction endonucleases are bacterial enzymes that bind and cleave DNA at specific target sequences. Type II restriction enzymes are the most widely used in molecular biology applications. They bind DNA at a specific recognition site, consisting of a short palindromic sequence, and cleave within this site, e.g., AGCT (for AluI ), GAATTC (for ... hillside high school nj athletics
