Chromosome duplication is a major mechanism by which new genetic material is generated. It can be defined as any duplication of a region of DNA that contains a gene.

Chromosome replication is a process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.

The main difference between replication and duplication of DNA is that replication is the synthesis of an exact replica of DNA while duplication is the doubling of the amount of DNA as a result of replication. Replication and duplication are two mechanisms that increase the amount DNA inside the nucleus.
