In a sense, that's all there is to DNA replication! But what's actually most interesting about this process is how it's carried out in a cell. Cells need to copy their DNA very quickly, and with …

During DNA replication, each of the cell’s chromosomes is copied, forming a pair of sister chromatids attached at the centromere, ready to be divided into two daughter cells.

DNA is properly replicated, the cell size is replicated properly and remains the same, and any damage that occurs in the healthy cell is repaired before cell division.

Copying of DNA by replication enzymes begins at a spot on the chromosome called the origin of replication. The origin is the first part of the DNA to be copied. As replication continues, the …

How might this process work? In a hypothetical example, a cell might first lose activity of a cell cycle inhibitor, an event that would make the cell’s descendants divide a little more rapidly.

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.

Replication occurs before cell division, during the S phase of the cell cycle. However, replication only concerns the production of new DNA strands, not of new cells.

Reproduction: Viruses cannot reproduce on their own; they require a host cell's ribosomes and other cell parts to replicate. Cells, on the other hand, have all the necessary components for …

A cell spends most of its life in interphase, which has three phases: G1, S, and G2. In the G1 phase, the cell grows and takes in nutrients. In the S phase, the cell's DNA is replicated. Each …
