Answer

Enzyme used to destroy DNA fragments

Answer

Domino effect of growing DNA strands

Answer

An enzyme that separate DNA fragments from smaller to larger fragments.

Question 4

Which of the following best describes as a protein that acts as DNA Scissors?

Accepted Answer

It is a group of nitrogenous isolated bacteria that cleave DNA sequences at sequence-specific sites, producing DNA fragments with a known sequence at each end. The use of restriction enzymes is critical to certain laboratory methods, including recombinant DNA technology and genetic engineering.

Answer

It is a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan. Plasmids are much used in the laboratory manipulation of genes.

Answer

It is an enzyme which brings about ligation of DNA or another substance.

Answer

It is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
