The enzyme that recognise a specific palindromic nucleotide sequence
Options
- AAlkaline phosphatase
- BDNA ligase
- CDNAse
- DRestriction endonuclease
Correct answer
D. Restriction endonuclease
Step-by-step solution
Each restriction endonuclease functions by ‘inspecting’ the length of a DNA sequence. Once it finds its specific recognition sequence, it will bind to the DNA and cut each of the two strands of the double helix at specific points in their sugar -phosphate backbones. Each restriction endonuclease recognises a specific palindromic nucleotide sequences in the DNA. Do you know what palindromes are? These are groups of letters that form the same words when read both forward and backward,
