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