Cell Cycle Flashcards
Gamete
a mature haploid male or female germ cell
Binary fission
asexual reproduction by a separation of the body into two new bodies
Gene
a unit of heredity which is transferred from a parent to offspring
Chromosome
a threadlike structure of nucleic acids and protein
Chromatid
each of the two threadlike strands into which a chromosome divides longitudinally during cell division
Centromere
the region of a chromosome to which the microtubules of the spindle attach,
Homologous Chromosome
two pieces of DNA within a diploid organism
Diploid
containing two complete sets of chromosomes, one from each parent.
Haploid
having a single set of unpaired chromosomes
Zygote
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
Karyotype
the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
Cell Cycle
a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and mitosis
interphase
the portion of the cell cycle that is not accompanied by observable changes under the microscope
Mitosis
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
Cytokinesis
the cytoplasmic division of a cell at the end of mitosis or meiosis
