Answer #1

1. Restriction enzymes are used to cut DNA.These are found in bacteria and archaea.Four types of restriction enzymes are founded.They are designated 1,2,3,4.This enzyme acts as a biochemical scissors.It is a protein.

2. Polony is a tiny colony of DNA.These are discrete clonal amplifications of a single DNA molecule.It has one micron in diameter.Solid phase polymerase chain reaction technique is the one kind of technique to form polony.

3. Plasmids are DNA molecules.It is separate from the chromosomal DNA.It is in circular.It can replicate independently.These are double stranded.
