meaning of occurrence of plasmid as an extra chromosomal material
Answers
Answer:
Explanation:
Plasmids are defined as extra-chromosomal genetic elements, occurring chiefly in bacteria and rarely in eukaryotic organisms. In bacteria, plasmids are circular double-stranded DNA molecules which contain genes controlling a wide variety of functions. In yeast (Saccharomyces cerevisiae) an RNA plasmid has been found.
Answer:
The occurrence of plasmid as an extra chromosomal material because bacterial cell is capable for replication.
The cell consists of both bacterial DNA and plasmid and gets replicate (self replication) then forms the two daughter cell.
The replication and formation or reproduce of new daughter cells are depends on
- Origin of replication
The replication is starts at a particular site of the cell from where firstly replication starts.
- A selectable marker gene
The cutting of DNA and select to transfer a gene to makes a disease free individuals.
- A cloning site
The point at which the replication starts and forms a same individual same as the parent body.
Plasmid done the self replication and forms same cloning as the parent body. It contains a small amount genes.
