Question

What are the four main stages of Interphase?

Answer 1

The stages of interphase are:

The stages of interphase are:

G1 (Gap 1), in which the cell grows and functions normally. During this time, much protein synthesis occurs and the cell grows (to about double its original size) - more organelles are produced, increasing the volume of the cytoplasm. If the cell is not to divide again, it will remain in this phase.
Synthesis (S), in which the cell duplicates its DNA (via semiconservative replication). This is also known as the Swanson phase.
G2 (Gap 2), in which the cell resumes its growth in preparation for mitosis.
In addition, some cells that do not divide often or ever, enter a stage called G0 (Gap zero), which is either a stage separate from interphase or an extended G1 phase, which follows the restriction point, a cell cycle checkpoint found at the end of G1.
