genes
|
A segment of DNA in which the sequence of nucleotides code for a specific protein (or part of a protein, which in turn produces a specific characteristic.
|
|
interphase
|
The phase of a cell's life cycle before cell division; genes are copied during this period.
|
|
Cell Division
|
The division of one cell into two cells; it includes mitosis and cytokinesis.
|
|
Mitosis
|
The duplicating and separating of a cell's chromosomes; usually followed by cytokinesis.
|
|
Cytokinesis
|
The division of the cytoplasm
during the process of cell division. |
|
sister chromatid
|
One of two identical chromosomes formed from one original chromosome during mitosis.
|
|
Prophase
|
The first phase of mitosis; chromosomes coil, and sister chromatids become obvious.
|
|
Metaphase
|
The second phase of mitosis; the chromosomes align by their centromeres across the middle of the spindle.
|
|
Anaphase
|
The third phase of mitosis; during this phase the daughter chromosomes move to opposite ends of the spindle.
|
|
Telophase
|
The last phase of mitosis; sister chromatids reach the ends of the spindle and the nucleus re-forms.
|
|
asexual reproduction
|
The production of a new organism without the joining gametes; reproduction that takes place by mitotic cell divisions.
|
|
budding
|
Asexual reproduction in which a portion of the parent separates from the parent to form a new organism.
|
|
regeneration
|
The ability to replace missing structures; in some organisms, serves as a method of asexual reproduction.
|
|
spore
|
A cell with a hard, protective covering, under favorable conditions it can produce a new organism.
|
|
sexual reproduction
|
The joining of haploid gametes to form a diploid zygote, which develops into a new individual.
|
|
meiosis
|
The process whereby one diploid cell forms haploid cells (gametes).
