Final answer:
DNA replication is the process where DNA makes an exact copy of itself. This is crucial for cell division, ensuring each new cell contains the same genetic material. The process is mostly accurate, but occasional errors can lead to mutations.
Step-by-step explanation:
The process in which DNA has the unique ability to make an exact copy of itself is known as replication. This critical process occurs before a cell divides, to ensure that each new daughter cell receives a precise copy of the DNA. DNA replication is a semi-conservative process where the two strands of the original double helix separate. Each strand serves as a template for the creation of a new complementary strand. Enzymes like DNA polymerases play a crucial role by adding nucleotides to form the new strand, which results in two identical DNA molecules, each consisting of one original strand and one new strand. The Importance of Accurate DNA Replication. Accurate replication is vital for maintaining the organism's genome integrity from one generation of cells to the next. However, sometimes errors occur during replication leading to mutations, which can cause hereditary and age-related diseases if not corrected. The enzymes involved in replication also have proofreading abilities to minimize the occurrence of such errors.
