replikaatsiooniga

Replikaatsiooniga refers to the process of replication in biology. This is the fundamental process by which a cell duplicates its DNA. Before a cell divides, it must ensure that each daughter cell receives an identical copy of the genetic material. This is achieved through DNA replication. The process begins with the unwinding of the double helix structure of DNA, facilitated by enzymes like helicase. Each strand then serves as a template for the synthesis of a new complementary strand. DNA polymerase is the key enzyme responsible for adding new nucleotides to the growing strands, following the base-pairing rules (adenine with thymine, and guanine with cytosine). Replication is a semi-conservative process, meaning that each new DNA molecule consists of one original strand and one newly synthesized strand. This ensures high fidelity and accuracy in transmitting genetic information from one generation of cells to the next. Errors can occur, but DNA repair mechanisms are in place to correct most of them.
