Gametes sperm and eggs; male and female reproductive cells. Somatic cells all other cells of the body that are not gametes. Daughter cells are genetically identical to parent cell. Functions of mitotic cell division: reproduction in asexually reproducing species, growth and repair in multicellular species. Daughter cells (ova, sperm) are genetically different from the parent cells: a single, long dna double helix that is wrapped around proteins in a highly organized manner. Dna encodes the cell"s hereditary information, or genetic material. Gene a length of dna that codes for a particular protein or ribonucleic acid (rna) found in the cell. 4 cell cycle phases: figure 11. 5; the cell cycle has four phases, g1 phase (interphase, s phase (interphase, g2 phase (interphase, mitotic (or m) phase.
