how many chromosomes are in one cell during g2 of interphase?
9942
A 2n = 26 organism will have 52 sister chromatids during G2 of interphase. An organism that is 2n = 26 is a diploid organism with 13 chromosomes. During S phase of interphase, each of the 13 chromosomes will be copied.

First, during the S phase of interphase, the genetic material of a cell is duplicated. A human has 46 chromosomes (a set of 23 you inherit from your mother, and a set of 23 from your father).
489371
We have 23 sets of chromosomes, 2 chromosomes per set = 46 chromosomes in each cell. But each chromosome has 2 DNA strands (that form the double helix), so 46 x 2 = 92 DNA strands/cell.

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2. How many DNA molecules are present in a chromosome of a cell in metaphase of mitosis?
191404
Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes.

Image of the cell cycle. Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
1276447
refers to the total number of chromosomes that a diploid cell contains. Cells, in human and animal context, typically have either one or two sets of chromosomes, which store DNA. A single set of human chromosomes contains 23 chromosomes, so there are "2n", or 46, total cells in a haploid human cell.
138975
During the first stage of meiosis, the HOMOLOGUES (1-23) are segregated into different cells, resulting in 2 cells that each have 1 copy of each of the 23 chromosomes (still duplicated from DNA replication).
1417735
The cellular DNA is replicated during interphase, resulting in the formation of two copies of each chromosome prior to the beginning of mitosis. As the cell enters mitosis, chromatin condensation leads to the formation of metaphase chromosomes consisting of two identical sister chromatids.
1340199
G2. The final part of interphase, between the end of S phase and the beginning of mitosis. G2 is an intermediate phase during which cells make certain they are ready to enter into mitosis.
1307787
At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
188304
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
28593
Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state.
67241
Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes.
104126
The eukaryotic cell spends most of its "life" in interphase of the cell cycle, which can be subdivided into the three phases, G1, S and G2. During interphase, the cell does what it is supposed to do.
1111863
After replication of the 46 chromosomes, the cell contains 92 chromatids (in 46 pairs). After mitosis two identical cells are created with the same original number of chromosomes, 46.
173306
Upon completion of telophase and cytokinesis, the single cell will be split into two cells. Each cell will contain 10 chromosomes, the same amount as the original progenitor cell.
