DNA Replication is a fundamental biochemical process that occurs in all living organisms, from bacteria to humans. It is the mechanism by which cells duplicate their genetic material, ensuring that each new cell receives an exact copy of the original DNA molecule. In this process, the double helix structure of DNA is separated into two single strands, which then serve as templates for the synthesis of new complementary strands. This synthesis is carried out by enzymes such as helicase, primase, and polymerase, which work together to unwind the DNA, add primer molecules, and catalyze the addition of nucleotides to the growing chain. DNA replication plays a critical role in cell division and growth, as it ensures that each daughter cell receives a complete set of genetic information. It is also essential for repairing damaged DNA and maintaining genomic stability. As a subcategory of biochemical processes within the field of biochemistry, DNA replication is studied using various techniques such as X-ray crystallography, biochemical assays, and computational modeling. These methods allow researchers to investigate the molecular mechanisms underlying DNA replication and better understand how this process is regulated in different organisms and cell types. In summary, DNA replication is a fundamental biochemical process that involves the duplication of genetic material in living organisms. It plays a critical role in cell division, growth, and genomic stability and is studied using various techniques within the field of biochemistry.
