Somatic cells divide regularly; all human cells (except for the cells that produce eggs and sperm) are somatic cells. … During interphase, the cell grows and DNA is replicated; during the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.
What are the steps of the somatic cell cycle in order?

What is the process of somatic cell division?
Mitosis is how somatic—or non-reproductive cells—divide. … In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells.
What is somatic cycle?
Somatic cell cycle consists of four phases while early embryonic cell cycle alternates between S and M phases without intervening G1 and G2 phases.
What are the three phases of the somatic cell cycle?
One “turn” or cycle of the cell cycle consists of three general phases: interphase, mitosis, and cytokinesis.
What happens in G1 phase?
G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.
What happens during each phase of the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
What do somatic cells do?
Somatic cells are the cells of the body that make up different tissues and organs. They are therefore important because they make up various parts of the body including all the internal organs, the connective tissue, and bones among others.
How do somatic cells reproduce?
In humans, such cells are diploid and reproduce using the process of mitosis to create identical diploid copies of themselves when they split. … Other types of species may have haploid somatic cells, and in these individuals, all of the body cells have only one set of chromosomes.
Why does mitosis occur in somatic cells?
In multicellular organisms, somatic (body) cells undergo mitosis to provide new cells for growth or to replace cells that have been damaged and died.
How does the function of a somatic cell differ from a bacterial cell?
Germ cells only contain one set of chromosomes; a somatic cell has a diploid number of chromosomes. … The process of germ cells is produced through meiosis; somatic cells are produced through the process of mitosis and cytokinesis.
What are somatic cells example?
Examples of somatic cells are cells of internal organs, skin, bones, blood and connective tissues. In comparison, the somatic cells contain a full set of chromosomes whereas the reproductive cells contain only half. … Synonym: body cells. Compare: sex cells.
What are the 4 stages of the cell cycle?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
