WebApr 10, 2024 · Definition. 00:00. …. DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends … WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.

DNA has four bases called adenine (A), thymine (T), … WebAny accidental changes in chromosome structure will be permanent. These changes will be passed on through future rounds of DNA replication. Therefore any loss of DNA is a serious problem. If the end of a DNA strand is not copied each time the DNA is replicated then the chromosome will shrink continuously as the cell cycle continues.
