The replication origin is a specific sequence in a genome where DNA replication begins, allowing for the duplication of genetic material before cell division. It is crucial for ensuring that the entire genome is accurately and completely copied, and its regulation is vital for maintaining genomic stability.

DNA replication is a fundamental process by which a cell duplicates its DNA, ensuring that each daughter cell receives an exact copy of the genetic material during cell division. This highly regulated process involves the unwinding of the double helix, synthesis of complementary strands, and proofreading to maintain genetic fidelity.

Cell division is a fundamental biological process where a single cell divides into two or more daughter cells, essential for growth, development, and repair in multicellular organisms. This process occurs through two main types: mitosis, which results in identical daughter cells, and meiosis, which leads to the production of gametes with half the number of chromosomes of the parent cell.

Regulation of genetic material

Genomic stability refers to the maintenance of DNA sequence and chromosomal integrity across cell divisions, ensuring proper cellular function and preventing diseases such as cancer. It is achieved through a range of cellular mechanisms that repair DNA damage, regulate cell cycle checkpoints, and maintain telomere length.
