Question

Read the given statements and select the correct option,
Statement 1 : Restriction endonuclease enzymes recongnise a specific palindromic nucleotide sequence in the DNA
Statement 2: Restriction endonuclease enzymes are called as molecular scissors or biological scissors.

Answer 1

Answer:

1. restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites.Restriction enzymes are one class of the broader endonuclease group of enzymes. Restriction enzymes are commonly classified into five types, which differ in their structure and whether they cut their DNA substrate at their recognition site.

2. Restriction enzymes are also called 'molecular scissors' as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.
