-stage outside the cell cycle in which cells do not copy their DNA and do not prepare to divide
-many cells, such as mature nervous cells in the human body, are in this stage
-regulatory proteins whose levels in a cell go up and down to stimulate the onset of specific stages of the cell cycle
coiled DNA found in the nucleus of a dividing cell
-each chromosome represents one highly coiled DNA molecule
-chromosome are rod-shaped
DNA in a non-dividing cell that is not tightly coiled
-allows transcription/translation to occur in the cell between cell divisions
result of DNA replication, genetically identical duplicate DNA molecule making up two halved of a doubled chromosome
-chromosome pairs that contain the same genes
-look like all other chromosomes, but contain genes which are different than all other chromosomes
-contains both halves of each homologous pair of chromosomes
-contains a full set of genetic information
-contains only 1/2 of the full set of genetic information
-contains only one chromosome from each homologous pair
