The information for the manufacture of ALL of these PROTEINS is contained in the DNA - HOW? ' ask, please, a simpler Q'n, thx.
Only Zygotes of certain species have 46 chromosomes.
A muscle cell has a diploid number of chromosomes, which is 46. The germ cells, such as the sperm and egg, have 23 chromosomes.
A primary spermatocyte will have 46 chromosomes or chromatids. Primary spermatocytes are diploid cells. Secondary spermatocytes are haploid cells with only 23 chromosomes.
They will also have 46 chromosomes.
There are 46 chromosomes in each cell. However, there are 23 in a sex cell e.g. 23 in an egg cell, 23 in a sperm cell to form 46 chromosomes for a embryo to develop.
Somatic cells (of the body) are diploid (having 46 chromosomes). Only gametes (eggs and sperm) are haploid (having 23 chromosomes). So that during fertilization the egg and sperm combine their chromosomes resulting in a new life with 46 unique chromosomes (in humans, of course. Others species has differing numbers of chromosomes). The haploid combination ensures genetic diversity.
Each cell has 46 chromosomes. Eggs and sperm each have 23, thus a human has 46.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
46 single chromosomes which is 23 pairs of chromosomes in one human body cell.
