A structure found in all eukaryotic cells. Contains genetic information: DNA and RNA.
Portion of the cell contained within the cell membrane, excluding the nucleus (jellylike)
Organelles in the cytoplasm carry out important functions of the cell
Components of body tissues; all cells in the body except for sex cells
GAMETES ( OR SEX CELLS)
- Ova: egg cells produced in female
: sex cells produced in male testes.
- (Somatic cells and gametes undergo different processes of cell
Undifferentiated cells in an embryo – totipotent: they can become any type of somatic cell
Double-stranded molecule that contains the genetic code, permanently remains in nucleus. CANNOT LEAVE THE NUCLEUS!
Single-stranded molecule, similar in structure to DNA but uses a different sugar and the base uracil in place of thymine. Can exit the nucleus.
Structures contained within the cytoplasm of eukaryotic cells that convert energy, derived from nutrients, into a form that is used by the cell (have own mtDNA) / the powerhouses
Structures composed of a specialized form of RNA and protein, The site of protein synthesis! (little factories)
- Tightly wound and condensed DNA along with
- some supporting proteins (300-2000 genes on each chromosome)
have 23 different chromosomes
