Structure formed by DNA and proteins that we find in the cell nucleus.
Human cells have 46 chromosomes
The two identical copies of a chromosome that form during S stage of
interphase
Tube-shaped cellular organelles
Cellular structure made of microtubules that separates chromosomes
during meiosis
Part of the chromosome that links sister chromatids and where the
spindle fibres attach
Pairing of homologous chromosomes that occurs during meiosis
Exchange of genetic material between homologous chromosomes that
results in recombinant chromosomes
First stage in mitosis or meiosis division
Second stage in mitosis or meiosis division
Third stage in mitosis or meiosis division
Fourth stage in mitosis or meiosis division
Couple of chromosomes that come from the father and the mother and
have the same genes but can have different alleles
Double membrane that separates nucleus from cytoplasm in an
eukaryotic cell
a plane in the equatorial region of the spindle in dividing cells, along
which the chromosomes become arranged during the metaphase.
Division of the cell cytoplasm
