Why does the Genome Size Differ in Different Organisms?

In the fields of molecular biology and genetics, the genome is the sum of all the genetic material of an organism. These genetic materials include DNA or RNA (viral RNA).

Genome size is the total number of DNA base pairs in a copy of the haploid genome.

Genome size vs.

All cells of an organism are derived from the same single cell, so they should have the same genome. However, in some cases, differences can occur between cells. During cell division

The genome is not just the sum of an organism's genes. The genome also contains other characteristics that can take into account specific genes and their products.

Replication plays an important role in the shaping of the genome. The scope of replication includes the extension of short tandem repeats, the replication of gene clusters, the entire chromosome and even the entire genome. This replication may be the basis for creating new genetic traits.
