It would be a problem because the stage of development will be affected and division will be stopped CELL alive.

Cell cycle is the sequence of events carried out between the formation of a cell and its division into daughter cells. The period of division phase is very small in comparison to total period at which cell grows and prepares for division.

Growth and preparatory phase is known as interphase. The division phase is divided broadly into nuclear division karyokinesis and cytoplasmic division cytokinesis.

Interphase is divided into three phases viz: G, S and G2 on the basis of biochemical events. G, phase or Gap 1 phase is the presynthetic phase.

Cell growth along with active synthesis of RNA and proteins are marked in this phase. The nuclear pool, amino acid and protein pools are also increased to meet the demand of the next phase.

S phase is the synthetic phase which follows the Gi phase. Synthesis of DNA occurs in this phase, which facilitates the duplication of chromosomes.

The DNA content is doubled and so are the genes. The duplicated genes are distributed equally between the two sister chromatids of the chromosome. The chromatids are held together at the centromere. Division phase follows the G7 phase. Two types of divisions are generally essential for continuity of life.

One type of division is marked in vegetative or somatic cells, where the daughter cell produced, is similar to the mother cell with regard to the chromosome number. The type of division is known as mitosis. However, the type of division marked in reproductive or germ cells produces daughter cells each of which contains half the chromosome number of the mother cell.

Such a division is known as meiosis. The cells of higher plants and animals contain tv. Sets of chromosomes, one set being replica of the other. Such cells are known as diploids.

In mit c divisions the 4C content is halved to 2C in daughter cells. But in meiotic division the daughter cell contains only 1 C DNA.The cell cycle is the complex sequence of events by which cells grow and divide.

In eukaryotic cells, this process includes a series of four distinct phases. These phases consist of the Mitosis phase (M), Gap 1 phase (G 1), Synthesis phase (S), and Gap 2 phase (G 2).The G 1, S, and G 2 phases of the cell cycle are collectively referred to as interphase.

Essay on Various Phases that Make Up the Cell Cycle - The two main phases that occur during a cell cycle are interphase and mitosis.

During most of a cell cycle, the cell spends a majority of its time in interphase resting in the cell cycle. The cell cycle is also known as cell division which is the continuity of life based on the reproduction of cells.

The stages of the cell cycle include interphase (which is made up of three stages: G1, S & G2), mitosis and cytokinesis.

The two main phases that occur during a cell cycle are interphase and mitosis. During most of a cell cycle, the cell spends a majority of its time in interphase resting in the cell cycle. Within interphase, the cell goes through 3 phases; 2 growth phases and DNA replication.

Following the end of DNA synthesis, there is a brief interval, G2 phase. The period from the end of the cell division to the beginning of the S phase is the G1 phase of the cell cycle.

Cells that leave the cell cycle enter a phase known as the G0 phase in which the process that initiates DNA replication is blocked/5(5).

Published: Mon, 5 Dec Interphase is a part of the cell cycle in which the cell reproduces more DNA, it is the time when a cell accomplishes the most this is the time that the cell is preparing to divide. Following the end of DNA synthesis, there is a brief interval, G2 phase. The period from the end of the cell division to the beginning of the S phase is the G1 phase of the cell cycle. Cells that leave the cell cycle enter a phase known as the G0 phase in which the process that initiates DNA replication is blocked/5(5). The two gap phases (G1 and G2) and S (for synthesis) phase, in which the genetic material is duplicated and an M phase, in which mitosis partitions the genetic material and the cell divides, make up the cell cycle. In G1 cellular content is duplicated accept chromosomes.

two cells in different phases of the cell cycle were fused to form a single cell with two nuclei. if one of the cells was in s phase and the other was in g1, the g1 nucleus immediately entered s phase.
