TERM 1
Autosome
DEFINITION 1
An autosome is a chromosome that is not an allosome.
Autosomes appear in pairs whose members have the same
form but which differ from other pairs in a diploid cell,
whereas members of an allosome pair may differ from one
another and thereby determine sex.
TERM 2
binary fission
DEFINITION 2
is the subdivision of a cell (or body, population, or species)
into two or more parts and the regeneration of those parts
into separate cells.
TERM 3
Cell Cycle
DEFINITION 3
is the series of events that take place in a cell leading to its
division and duplication.
TERM 4
Chromatid
DEFINITION 4
contains the replicated DNA of each individual chromosome,
which are joined by a centromere, for the process of cell
division.
TERM 5
Chromatin
DEFINITION 5
is the combination of DNA and proteins that make up the
contents of the nucleus of a cell. The primary functions of
chromatin are 1) to package DNA into a smaller volume to fit
in the cell, 2) to strengthen the DNA to allow mitosis, 3) to
prevent DNA damage, and 4) to control gene expression and
DNA replication.

Autosome

An autosome is a chromosome that is not an allosome. Autosomes appear in pairs whose members have the same form but which differ from other pairs in a diploid cell, whereas members of an allosome pair may differ from one another and thereby determine sex. TERM 2

binary fission

DEFINITION 2 is the subdivision of a cell (or body, population, or species) into two or more parts and the regeneration of those parts into separate cells. TERM 3

Cell Cycle

DEFINITION 3 is the series of events that take place in a cell leading to its division and duplication. TERM 4

Chromatid

DEFINITION 4 contains the replicated DNA of each individual chromosome, which are joined by a centromere, for the process of cell division. TERM 5

Chromatin

DEFINITION 5 is the combination of DNA and proteins that make up the contents of the nucleus of a cell. The primary functions of chromatin are 1) to package DNA into a smaller volume to fit in the cell, 2) to strengthen the DNA to allow mitosis, 3) to prevent DNA damage, and 4) to control gene expression and DNA replication.

Chromosomes

is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. TERM 7

Cytokinesis

DEFINITION 7 is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. TERM 8

DNA

DEFINITION 8 is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. TERM 9

DNA replication

DEFINITION 9 is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. TERM 10

Duplicated Chromosome

DEFINITION 10 Condensed chromatin that is preparing for cell reproduction/division.it consist of a sister chromatid and its exact copy of a sister chromatid

Spindle

composed of microtubles , along which the chromosomes are distributed in mitosis and meiosis.
