gamete
--a haploid REPRODUCTIVE CELL that unites with another haploid reproductive cell to form a ZYGOTE
is single but sounds like half; for sexual reproduction so only needs to supply half
binary fission
--a form of ASEXUAL REPRODUCTION in single celled organisms by which one cell DIVIDES into two cells of the same size
gene
--a SEGMENT OF DNA that is located in a chromosome and that codes for a specific hereditary trait
genes make up chromosomes
chromosome
--in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA

centromere
--the region of the chromosome that HOLDS THE TWO SISTER CHROMATIDS TOGETHER during mitoses
central location
homologous chromosome
--chromosomes that have the SAME SEQUENCE OF GENES that have the same structure, and that pair during meiosis
homo=same
chromosomes have genes;
pairs
haploid
--describes a cell nucleus or organism that has only ONE SET OF UNPAIRED CHROMOSOMES
diploid
--a cell that contains TWO HAPLOID SETS of chromosomes
