thread-like structures located inside the nucleus of cells. made of DNA. |
|
|
DNA |
genetic code |
|

centromere |
middle of chromosome that links sister chromatids together |
|
|
tumor |
a swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant. |
|
|
egg |
Part of female reproductive system |
|
|
autosome |
a chromosome that isn't a sex chromosome |
|
|
diploid |
from a cell or nucleus- containing two complete sets of chromosomes, one from each parent. |
|
|
mitosis |
a part of cell cycle where chromosomes in a cell nucleus are separated into two identical sets of chromosomes. each set ends up in its own nucleus. |
|
|
interphase |
the phase of the cell cycle in which a typical cell spends most of its life. cell copies its DNA prepping for mitosis. |
|
|
homologous chromosome |
one chromosome pair from father one from mother each has the same genes in same order but the traits may vary |
|
|
chromatin |
a complex of DNA and proteins that forms chromosomes within the nucleus of euk cells. doesn't appear in strands |
|
|
histone |
proteins found in euk cell nuclei that package and order the DNA into structural units called nucleosomes chief protein compounds |
|
|
chromatid |
thread like strands chromosomes divide into |
|
|
cancer |
when cells take advantage of the cell division cycle and only goes through mitosis |
|
|
sperm |
part of male reproductive system |
|
|
karyotype |
the number and appearance of chromosomes in the nucleus of a euk cell or the complete set of chromosomes in a species
|
|
|
haploid |
a cell that has half the usual number of chromosomes than normal
|
|
|
zygote |
euk cell formed by fertilization between two gametes, sharing DNA from both and has all necessary genetic code for another being
|
|
|
meiosis |
reproduction process that reduces the number of chromosomes in the parent cell by half and produces four gamete cells
|
|
|
cytokinesis |
process of cell division in animal cells that divide the cytoplasm of a parental cell into two daughter cells
