bacteriophage takes over a bacterium's genetic machinery and directs it to make more viruses
nucleotides the small units that make up DNA
double helix in which two strands of DNA wind around each other like a twisted ladder
base pairing rules t=a c=g
replication the process by which DNA is copied during the cell cycle
DNA polymerases bonds the new nucleotides together
cell cycle the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells
mitosis the division of the cell nucleus and its contents
cytokinesis the process that divides the cell cytoplasm
chromosome one long continuous thread of DNA that consists of numerous genes along with regulatory information
histones each of your chromosomes is associated with a group of proteins
chromatin loss combination of DNA and proteins
chromatid one half of a two identical chromatids are called sister chromatids
centromere a region of the condensed chromosome that looks pinched
somatic cell also called body cells
gamete sex cell- sperm and egg
homologous chromosomes two chromosomes- one from father, one from mother
autosomes chromosomes that contains genes for characteristics not directly related to the sex of an organism
sex chromosomes directly control the development of sexual characteristics
sexual reproduction involves the fusion of two gametes that results in offspring that are a genetic mixture of both parents
fertilization actual fusion of an egg and a sperm cell
diploid means a cell has two copies of each chromosomes
