one characteristic of life
long, slightly acidic molecules made up of small monomers of nucleotides
the building block of nucleic acids; includes a 5-carbon sugar, a phosphate group, and a nitrogenous base
weak chemical forces that hold complementary base pairs together in DNA
the bonding between A and T nucleotides and G and C nucleotides in DNA
parallel strands of DNA that run in opposite directions.
the process of duplicating DNA before cell division.
enzyme that “unzips” a molecule of DNA into two strands during DNA replication
enzyme that lays down RNA primers during replication; serves as a starting point for DNA polymerase
enzyme that joins nucleotides to synthesize a new complementary strand of DNA during DNA replication.
the tips of eukaryotic chromosomes
the process by which a cell divides into two new daughter cells
the production of genetically identical offspring from a single parent
the production of genetically variable offspring from two reproductive cells
genetic information tightly bundled into packages of DNA
substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
one of two identical sister parts of a duplicated chromosome
region of a chromosome where the two sister chromatids attach
structure in an animal cell that helps to organize cell division.
the series of events that take place as a cell grows and divides
first and longest phase of mitosis; genetic material in the nucleus condense and chromosomes become visible
phase of mitosis in which the chromosomes line up in the center of the cell
phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
the division of cytoplasm to form two separate cells
