cell reproduction?

Post by deostroll » Sun May 28, 2006 7:34 am

I've been wondering lately how cells produce. I know that there are two kinds of cell reprodution - mitosis and meosis. My question is a cell (i.e. any cell) capable of reproducing both the ways? If so, how does the cell know which way it has to reproduce.

Mitosis is normal cell division, which produces two identical copies of the original cell.

Meiosis is the production of sex cells, in which one cell produces four sex cells, each of which have only half the DNA of the original.
Generally speaking, the more people talk about "being saved," the further away they actually are from true salvation.

Meiosis is used to make sperm and egg cells with only a single set of genetic information as opposed to a double set like your other cells. Later when a sperm unites with an egg that cell, the zygote, will have the double set and be ready to proliferate for all other cells of the new human( or whatever).
