What are palindromes in DNA give example?

A palindromic sequence is a sequence made up of nucleic acids within double helix of DNA and/or RNA that is the same when read from 5′ to 3′ on one strand and 5′ to 3′ on the other, complementary, strand. An example of a palindromic sequence is 5′-GGATCC-3′, which has a complementary strand, 3′-CCTAGG-5′.

What is a palindromic restriction site?

A DNA locus whose 5′-to-3′ sequence is identical on each DNA strand. The sequence is the same when one strand is read left to right and the other strand is read right to left. Recognition sites of many restriction enzymes are palindromic.

How do you identify a palindrome sequence?

For a nucleotide sequence to be considered as a palindrome, its complementary strand must read the same in the opposite direction [2]. For example, the sequence 5′-CGATCG-3′ is considered a palindrome since its reverse complement 3′-GCTAGC-5′ reads the same. Palindromes can be exact or approximate.

Why is same Ren used to cut vector and source DNA?

Restriction enzymes cut at specific sequences so the same restriction enzyme must be used because it will produce fragments with the same complementary sticky ends, making it possible for bonds to form between them. Their sticky ends match, and so they can be ligated together.
