Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase. DNA double-strand breaks can be repaired during interphase by two principal processes. [5] The first process, non-homologous end joining (NHEJ), can join the two broken ends of DNA in the G1, S and G2 phases of interphase.

Interphase consists of three main phases: G 1, S, and G 2. G 1 is a time of growth for the cell where specialized cellular functions occur in order to prepare the cell for DNA replication. [16] There are checkpoints during interphase that allow the cell to either advance or halt further development.
Nuclear pores crossing the nuclear envelope The nuclear envelope is punctured by around a thousand nuclear pore complexes , about 100 nm across, with an inner channel about 40 nm wide. [ 9 ] The complexes contain a number of nucleoporins , proteins that link the inner and outer nuclear membranes.
An interphase nucleus (left) and a set of mitotic chromosomes (right) from human tissue culture cells. Bar, 10 μm. Condensins are large protein complexes that play a central role in chromosome assembly and segregation during mitosis and meiosis (Figure 1).
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
Mitosis in an animal cell (phases ordered counter-clockwise), with G 1 labeled at left. The G 1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in
