DNA Replication
DNA replication is the process by which DNA molecules create exact copies of themselves. It occurs in all living organisms and is the basis for biological inheritance. In the context of chromosomes, DNA replication plays a crucial role in cell division and growth. Prior to cell division, each chromosome is duplicated through this process so that when the cell splits, each new cell receives an identical set of chromosomes containing the same genetic information. This mechanism ensures the faithful transmission of genetic material from one generation to the next, making it a fundamental aspect of genetics and a critical component in understanding how traits are passed down through families.
