nondisjunction

error in meiosis in which homologous chromosomes fail to separate

deletion

error in meiosis in which a part of DNA from a chromosome is lost

inversion

error on meiosis in which the order of the genes in a section of a chromosome is reversed and reattached to the same chromosome

duplication

error in meiosis in which a part of chromosome is repeated

translocation

error on meiosis in which the order of the genes in a section of a chromosome is reversed and reattached to a different chromosome

germ-cell mutation

mutation that occurs in the gametes, can't affect the organism but can be passed to its offspring

somatic cell mutation

mutation that occurs in the skin cell, can affect the organism but can't be passed to its offspring

lethal mutation

a mutation that causes death

chromosome mutation

a mutation that gives way for nondisjunction, deletion, inversion, duplication, or translocation

gene mutation

a mutation in the sequence of the bases in a gene
changes the structure of the polypeptide that the gene codes for

point mutation

a mutation in which one or just a few nucleotides in a gene are changed

substitution

a mutation that affects a single nucleotide by substituting one nucleotide for another one

frame-shift mutation

a mutation that affects the reading frame because of an addition or subtraction of a nucleotide

human genome project

a research effort to sequence and locate the entire collection of genes in human cells

recombinant DNA

DNA produced by combining DNA from different sources

gene cloning

using bacteria to make multiple copies of a gene

plasmid

found in bacterial cells, but are not part of the bacterial cell's necessary DNA

sticky ends

single-stranded ends formed when restriction enzyme cuts DNA

restriction enzymes

enzyme that cuts DNA at a specific sequence of nucleotides

doner gene

donated genes
