|
chromosome |
proteins & DNA in a coiled, rod shaped from that occurs only during cell division |
|
|
chromatid |
one of the chromosomes that links sister chromatids and where the spindle fibers attach during cell division |
|
|
DNA |
Deocyribonycleic Acid- stores genetic info |
|
|
Gene |
segment of DNA that codes (gives instructions) for a particular trait |
|
|
Homologous Chromosomes |
Pairs that are identical in size, shape, centromere location and same gene location |
|
|
Haploid |
A cell that contains ONE chromosome of a homologous pair (N) Gametes |
|
|
Diploid |
A cell that contains BOTH chromosoems of a homologous pair (2N) Fertilized egg, somatic cells |
|
|
Autosomes |
chromosome pairs 1-22, Basic traits |
|
|
Karyotype |
The characterization of the chromosomes complement of a species (such as the shape, type, number, etc. of chromosomes). To arrange and classify the chromosome complement of an organism based on the number, size, shape, and other characteristics of the chrmosomes |
|
|
Sex chromosome |
A type of chromosome in the genome that is involved in the determination of the sex as well as the development of sexual characteristics in an organism. it occurs in pairs in somatic cells while singly in sex cells (Gametes) |
|
|
Mitosis |
The process where a single cell divides resulting in generally two identical cells, each containing the same number of chromosomes and genetic content as that of the original cell |
|
|
Cell cycle |
The sequence of growth and division of a cell; consists of interphase (G1, S, G2), mitosis, and cytokinesis |
|
|
Interphase |
the phase in the life cycle of a cell where in the cell is not undergoing cell division (as compared to mitosis and meiosis) |
|
|
Cytokinesis |
The division of the cytoplasm and the plasma membrane following the division of the nucleus resulting into two cells, each having its own nucleus and cytoplasm surrounded by a plasma membrane. |
