Document Summary
Eukaryotic cells b. c. i. ii. iii. iv. v. vi. vii. viii. ix. x. xi. Body cells - also called somatic cells or diploid cells. Includes nearly all the cells in an organism: lung, brain, blood, tissue, etc. Sex cells - also called gametes or haploid cells. This is ova/ovum in females and sperm in males. The sole purpose is to combine with other gametes and produce an offspring. Mitochondrions are responsible for supplying the cell with energy. mtdna creates proteins to be used by the mitochondrion. Always inherited from the mother; to pass on to grandchildren, the mother must have a daughter mtdna changes very slowly; this makes it easy to track evolutionary lineage; he individual the mtdna started with is called mitochondrial eve. Makes proteins for the rest of the cell. Deoxyribonucleic acid; contains the genetic code for biological structures & means to translate the code. Composed of phosphate & sugar backbone, nucleotide base pairs:
