Cell Cycle and Mitosis Cycle

By Cris Cisneros

Gamete

a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

Binary Fission

is a form of asexual reproduction and cell division used by all prokaryotes

Gene

is a locus of DNA that encodes a functional RNA or protein product, and is the molecular unit of heredity

Chromosones

are thread-like structures located inside the nucleus of animal and plant cells

Chromatid

is one copy of a newly replicated chromosome, which typically is joined to the other copy by a single centromere

Centromere

is the part of a chromosome that links sister chromatids

Homologous Chromosones

are similiar but not identical Each carries the same genes in the same order, but the alleles for each trait may not be the same

Diploid

a diploid cell, organism, or species.

Haploid

is the term used when a cell has half the usual number of chromosomes.

Zygote

is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual.

Autosome

is a chromosome that is not an allosome - an example is a sex chromosome

Sex chromosome

a chromosome involved with determining the sex of an organism, typically one of two kinds

Karyotype

is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.

SECTION 2

Cell cycle

is the series of events that take place in a cellleading to its division and duplication

Interphase

is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions

Mitosis

is a part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.

Cytokinesis

They are released by cells and affect the behavior of other cells.

Cancer

the disease caused by an uncontrolled division of abnormal cells in a part of the body

SECTION 3

Spindle

composed of microtubules, that forms near the cell nucleus during mitosis or meiosis and, as it divides, draws the chromosomes to opposite poles of the cell.
