Term | Definition |
meiosis | special cell division process that creates gametes |
diploid | 2n; body cell with a full set of chromosomes |
haploid | n; sex cell with half the normal # of chromosomes |
gamete | sex cell |
somatic cell | normal body cell |
sperm | male gamete |
egg | female gamete |
zygote | fertilized egg formed by fertilization |
n | haploid (half) |
2n | diploid (di=2) |
fertilization | joining of sperm and egg to create a zygote |
crossing over | exchange of genes from one homologous chromosome to another during meiosis |
nondisjunction | failure of chromosomes to separate correctly during division |
gene | a segment, or piece, of DNA |
DNA | instructions for making proteins; the "code of life." |
chromosome | long, condensed strands of DNA |
nitrogen base | part of a nucleotide; adenine, thymine, guanine, cytosine, uracil |
ribosome | site of protein synthesis in cells |
protein synthesis | the process of making proteins |
transcription | first stage of protein synthesis; mRNA is created from a segment of DNA |
translation | second stage of protein synthesis; codons are read and amino acids are assembled into proteins |
amino acid | building block of proteins |
mRNA | messenger; copy of DNA instructions |
tRNA | transfer; brings amino acids to ribosomes |
rRNA | ribosomal; ribosomes- puts amino acids together |
trait | characteristic or attribute expressed by genes |
mutation | error or change in DNA bases |
allele | form of a gene |

homozygous | genotype with two of the same alleles |
dominant | allele that hides the recessive and is always expressed |
recessive | allele masked by the dominant and can only show when 2 recessive alleles are present |
hybrid | two different alleles; heterozygous |
sex-linked trait | trait or gene carried on the sex chromosomes, usually x-linked |
pedigree | a diagram that shows the inheritance of a trait over generations |
genetic engineering | technology that involves the altering of genes and DNA in organisms |
gene splicing | removing a gene from one organism and inserting it into the DNA of another organism |
recombinant DNA | DNA formed by gene splicing |
cloning | creating identical genetic copies of organisms |
gel electrophoresis | tool and technique used to create a DNA fingerprint/banding pattern |
DNA fingerprint | an individual's unique sequence of DNA created using gel electrophoresis |
