(a) Plasmid DNA and Chromosomal DNA
(b) RNA and DNA
(c) Exonuclease and Endonuclease
A) Plasmid DNA
◆Plasmid DNA Chromosomal DNA
It is an extra chromosomal DNA molecule found in bacteria, capable of replicating and is independent of chromosomal DNA
Chromosomal DNA
◆It forms the complete DNA of an entity found inside the chromosomes
(b) RNA and DNA
B) RNA
◆Single-stranded molecule
◆Cannot replicate by themselves
◆Consist of ribose sugar
◆Pyrimidines are uracil and adenine
◆It is a component of ribosomes
DNA
◆Double-stranded molecule ◆Have the potential to replicate
◆Consists of deoxyribose sugar
◆Pyrimidines are thymine and adenine
◆It is a component of chromosomes
C) Exonuclease
◆It is a kind of restriction enzyme which removes the nucleotides from 5’ or 3’ terminals of the DNA molecule.
Endonuclease
◆It is a kind of restriction enzyme that snips within the DNA at particular sites to produce sticky ends.
