Term
|
Definition
| is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction. |

Definition
-
the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete that travels to fuse with a larger stationary gamete produced by the other (female).

-
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

-
the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.

Definition
-
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells.

|
Definition
-
the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
|
|
|
Term
|
Definition
-
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
|
|
|
Term
|
Definition
-
the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
|
|
|
Term
|
Definition
-
the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.

Definition
-
the point on a chromosome by which it is attached to a spindle fiber during cell division.
|
|
|
Term
|
Definition
-
each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.

Term
|
Definition
-
a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
|
|
|
Term
|
Definition
-
the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
|
|
|
Term
|
Definition
-
the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
|
|
|
Term
|
Definition
-
the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
