DNA replication is the process by which a double-stranded molecule of a DNA is replicated(copied) to produce two morphologically and chemically identical DNA molecules.

Replication is a very important process for the living organism, because in a cell division, the two new daughter cells are produced which must contain the same genetic information or the DNA just like the parent cell. It cant be less or more than the parent cell.

Replication occurs in three major steps,

1- the opening of the double helix and separation of the DNA strands,

2- the priming of the template strand.

3- the assembly of the new DNA segment.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
