Palindromic sequences: nucleic acid sequences where the one strand matches its complementary strand when read in the same direction. What Is a DNA Palindrome? A palindromic sequence of nucleotides (which are labeled A, T, C, or G) occurs when complementary strands of DNA read the same in both directions, either from the 5-prime end or the 3-prime end. Restriction enzymes are traditionally classified into four types on the basis of subunit composition, cleavage position, sequence specificity and cofactor requirements. What are the three types of restriction enzymes? … What is a palindromic number?Ī palindromic number is the same number that is read forward and backwards. For example the recognition sequence for BamHI is GGATCC. These enzymes predictably cut both strands because the sequences they recognize are palindromic. Restriction enzymes cut double-stranded DNA * at specific locations based the pattern of bases found at those locations. The role of palindromic sequences called clustered regulatory interspaced short palindromic repeats (CRISPR) found in bacteria and archaea genome is basically to provide immunity against foreign genetic elements such as plasmids (Barrangou et al., 2007) and phages (Marraffini and Sontheimer, 2008). What is the purpose of palindromic sequence? 5′ to 3′) on one strand matches the sequence reading in the opposite direction (e.g. What is palindromic sequence give examples?Ī palindromic sequence is a nucleic acid sequence in a double-stranded DNA or RNA molecule wherein reading in a certain direction (e.g. … A palindromic sequence also increases the chance that both strands of DNA are cut. It binds to the DNA only in one specific configuration. Why restriction enzyme has a palindromic sequence?Įxplanation: Enzymes such as restriction enzymes have to recognize a very specific sequence in order to carry out its task. These are generally palindromic sequences (because restriction enzymes usually bind as homodimers), and a particular restriction enzyme may cut the sequence between two nucleotides within its recognition site, or somewhere nearby.
