Conjugation
Conjugation means two cells are coming together for a certain time and making DNA transfer.DNA transfer is done with two cells which have different genetical properties and its done with the help of cytoplasm bridge or connection likea tube shape.
-bacterias
-paramesium can do conjugation.
In bacterias , DNA transfer is happen in one way.The bacterias that only have plasmid can do DNA transfer to the other cell.Because plasmid is a molecule that reproduce independent with cell's chromosomes and it has two circular shape DNA in it.DNA pieces that bacterias transfered is called F plasmid.Cell that carries plasmid is called F+ , the cell that doesn't have plasmid is called F-.The cell that gives plasmid attaches the other cell with its pillus.Then they form cytoplasmic bridge between them.Transmitter cell's one of the DNA circle opens and with the help of cytoplasmic bridge it gives into receiver cell.After the DNA transfer, both DNA coppies themselves and they have two circle plasmid inside of them.Now the separated cells have turned into transmitter (F+).After the conjugation genetic variation is provided.In conjugtion number of cells doesn't change.
