What is the difference between a germ line cell and a somatic cell?
Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis.
Are germ or somatic cells haploid?
Whereas somatic cells are diploid, meaning they have two copies of each chromosome, germ cells are haploid. The haploid nature of germ cells is vital to the process of sexual reproduction.
Are germline cells diploid?
Germ line cells are haploid, which means they contain a single set of chromosomes. In diploid cells, one set of chromosomes is inherited from the individual’s mother, while the second is inherited from the father.
What is an example of a somatic mutation?
Somatic mutations can arise during the course of prenatal brain development and cause neurological disease—even when present at low levels of mosaicism, for example—resulting in brain malformations associated with epilepsy and intellectual disability.
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.
How many somatic cells do humans have?
There are approximately 220 types of somatic cell in the human body. Theoretically, these cells are not germ cells (the source of gametes); they transmit their mutations, to their cellular descendants (if they have any), but not to the organism’s descendants.
What are the types of somatic cells in your body?
Somatic cells are all cells of the body apart from gamete (sperm cells and egg cells). As such, they include cells that make up different parts of the body including liver cells, skin cells, and bone cells among others. Mature somatic cells are highly specialized and therefore perform very specific functions.
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.
