Anaphase
The phase of mitosis and meiosis in which each kinetochore fiber pulls toward the originating centrosome and divides the sister chromatids (in mitosis and meiosis-ll) or divides the homologous pair (in meiosis-1)
Apoptosis
The programmed cell death during which cell membrane makes blebs which break from the cell and are phagocytosed by other cells
Advertisement
Cell cycle
The series of events from the time a cell is produced until it completes mitosis" and produces new cells
Chiasmata
The complexes formed between the non-sister chromatids of homologous chromosomes during meiosis
Advertisement
Crossing over
The exchange of segments between the non-sister chromatids of homologous chromosomes during meiosis
GO phase
The phase of the cell cycle in which a cell remains quiescent and does not divide or prepare for division
G1 phase
The phase of interphase in which the cell increases its supply of proteins makes new organelles, grows in size, and makes enzymes for the next phase
Advertisement
G 2 phase
The phase of interphase in which the cell prepares proteins for the production of spindle fibers
Homologous chromosomes
Morphologically similar chromosomes with genes for the same characters
Chromosomes
One of the rod-shaped bodies found in the nucleus of cells contains genetic information (DNA)
Advertisement
Kinetochore
The complex made of proteins that is attached with the centromere of the chromosomes
Advertisement
Malignant
Not benign: (For tumors) which break from the site of their production and invade other tissues
Metaphase
The phase of cell division in which two kinetochore spindles from opposite sides attach with each chromosome in mitosis and meiosis-Il) or with homologous pair (in meiosis-1) and metaphase plate is formed
Advertisement
Mitosis
The cell division in which each two daughter cells has the same number of chromosomes as were present in the parent cell
Non-sister chromatids
Non-sister chromatids are different and are located on different chromosomes.
Advertisement
Prophase
In the first phase of mitosis in meiosis which the chromatin condenses and spindles are formed, crossing over occurs during the prophase of meiosis-1
Advertisement
S phase
The phase-in interphase during which the chromosomes are duplicated i.e. new chromatids are formed
Telophase
The last phase of karyokinesis during which nuclear envelopes is reformed and chromosomes uncoil to form chromatin
Advertisement
Metaphase plate
The arrangement of chromosomes on spindle fibres along the equator of the cell
Advertisement
Open mitosis
The mitosis in which the spindle fibers are formed outside the nuclear envelope
