the basic unit of structure and function in living things

any cell of a living organism other than the reproductive cells

a series of events in which a cell grows, prepares for division, and divides to form two daughter cells

the resting period of the cell cycle between cell divisions

cell division in which the nucleus divides into nuclei containing the same number of chromosomes

an organism's genetic material

threadlike structures made of DNA molecules that contain genetic information

a macromolecule that helps build and maintain body cells and tissues, and determines the size, shape, color, and other traits of an organism

division of the cytoplasm to form two separate daughter cells

a change in the nucleotide sequence of a gene

a molecule made of a nitrogen base, a sugar, and a phosphate group

the twisted ladder shape of DNA, formed by two nucleotide strands twisted around each other

one of two identical "sister" parts of a duplicated chromosome

Adenine, Thymine, Guanine, Cytosine

the original strand of DNA that is copied during DNA synthesis

the two identical strands of DNA that are created as a result of DNA synthesis

the process of copying DNA prior to cell division

a mutation in which one or more pairs of nucleotides are removed from a gene

the addition of one or more nucleotide base pairs into a DNA sequence

protein structures which move the chromosomes during cell division

a double membrane that surrounds the nucleus in the cell

the area where the chromatids of a chromosome are attached

contain 2 copies of each chromosome

having a single set of unpaired chromosomes

a sequence of DNA that codes for a protein and thus determines a trait
