Restriction enzymes are also known as

Read the following four statements (A-D) about certain mistakes in two of them: The first transgenic buffalo Rosie produced milk which was human alpha-lactalbumin enriched. Restriction enzymes are used in isolation of DNA from other macro-molecules Downstream processing is one of the steps of R-DNA technology. Disarmed pathogen vectors are also used in transfer of R-DNA into the host.

Restriction endonucleases are useful in

The restriction enzymes that are used in construction of recombinant Dna molecule are endonucleases which cut the DNA at 'specific recognition sequence'. What would be the disadvantage if they would not cut the DNA at specific -recognition sequence?

Name the enzymes involved during replication of DNA
