base pairing
principle that bonds in DNA can form only between adenine and thymine and guanine and cytosine
replication
process of copying DNA prior to cell division
DNA polymerase
principal enzyme involved in DNA replication
metaphase
phases of mitosis which the chromosomes line up across the center of the cell
cell division
process by which a cell divides into two daughter cells
asexual reproduction
process of reproduction involving a single parent that results in off spring that are genetically identical to the parent
sexual reproduction
type of reproduction in which cells from two parents unite to form the first cell of a new organism
chromosome
threadlike structure of DNA and protein that contains genetic info; eukaryote and chromosomes are found in the nucleus. Prokaryotes are found in the cytoplasm
anaphase
phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
cell cycle
series of events in which a cell grows, prepares for division and divides to form two daughter cells
interphase
period of the cell cycle between cell division
mitosis
part of eukaryotic cell division during which the cell nucleus divides
cytokinesis
division of the cytoplasma to form separate daughter cells
chromatid
one of two identical “sister” parts of a duplicated chromosome
centromere
region of a chromosome which the two sister chromatids attach
centriole
structure in an animal cell that helps to organize cell division
cyclin
one of the family proteins that regulates the cell cycle in eukaryotic cells
cancer
disorder in which some of the body cells lose the ability to control growth
prophase
first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
telophase
phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
