mutation		Any change of or random error in a DNA sequence
meiosis		In plants, the loss of water through leaf stomata by evaporation.
messenger RNA		The name of the molecule that contains a genetic code
chromosome		RNA that transports information from DNA in the nucleus to the cell's cytoplasm
homozygous		Male and female cells; sperm and eggs.
genetics		Process is the cell nucleus where enzymes make an RNA copy of a DNA strand
dominant		When there are two different alleles for a trait.
haploid		When there are two identical alleles for a trait
allele		Alternative form of a gene for each variation of a trait of an organism.
recessive		Cell with one of each kind of chromosomes; is said to contain a haploid or n, number of chromosomes.
translation		Combination of genes in an organism
DNA		Type of cell division where one body cell produces four gametes, each containing half the number of chromosomes as a parent's body cell.
genotype		Outward appearance of an organism, regardless of it's genes
diploid		Branch of biology that studies heredity.
double helix		Cell with two of each kind of chromosomes; is said to contain a diploid,or 2n, number of chromosomes
gametes		Trait of an organism that can be masked by the dominant form of a trait.
heterozygous		Shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure and held together by hydrogen bonds between the base.
phenotype		Observed trait of an organism that masks the recessive form of a trait.
transcription		Period of nuclear cell division in wich two daughter cells are formed, each containing a complete set of chromosomes.
mitosis		Formed from DNA , contains many genes.
