What is an example of a somatic cell?
Every other cell type in the mammalian body, apart from the sperm and ova, the cells from which they are made (gametocytes) and undifferentiated stem cells, is a somatic cell; internal organs skin, bones, blood and connective tissue are all made up of somatic cells.
What is the difference between somatic cells and germ cells quizlet?
somatic cells are all cells except sex cells. germ cells divide by meiosis to form sex cells, all other cells are somatic cells.
What is your germ line?
(JERM-line …) The DNA in germ cells (egg and sperm cells that join to form an embryo). Germline DNA is the source of DNA for all other cells in the body.
What is the other name of somatic cell?
A somatic cell (from Ancient Greek σῶμα sôma, meaning “body”), or vegetal cell, is any biological cell forming the body of a multicellular organism other than a gamete, germ cell, gametocyte or undifferentiated stem cell.
What are the two types of somatic cells in your body?
Some examples of somatic cells include nerve cells, skin cells, and blood cells. Germ cells have half the number of chromosomes that somatic cells have.
What occurs in germ cells?
Germ cells differentiate to produce male and female gametes, sperm and unfertilized eggs (oocytes or ova), and undergo meiosis to produce a haploid set of chromosomes. Haploid gametes then unite to form a diploid zygote that develops into a new individual.
Why are somatic mutations not transmitted to offspring?
Somatic cells give rise to all non-germline tissues. Mutations in somatic cells are called somatic mutations. Because they do not occur in cells that give rise to gametes, the mutation is not passed along to the next generation by sexual means.
What causes germ cell mutation?
Germinal mutations can be caused by radiation or chemical mutagens and may affect a single gene or an entire chromosome. A germinal mutation affects the progeny of the individual in whose reproductive cells the mutation arose and subsequent generations of that progeny.
What is somatic cell mutation?
Listen to pronunciation. (soh-MA-tik myoo-TAY-shun) An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children.
In what kind of cells do mutations occur quizlet?
Inherited mutations are present in all cells of the body and are faithfully copied every time body cells divide. These hereditary mutations are also called germ-line mutations because the gene changes are in the sperm and egg cells (arise from germ cells) and can be passed from parent to child.
