Cell Cycle Mitosis and Meiosis
Terms in this set (30)
Process by which a cell divides into two new daughter cells
A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells. Each chromosome consists of one very long DNA molecule and associated proteins
series of events that cells go through as they grow and divide
Period of time where a cell carries on metabolism and replicates chromosomes prior to cell division
a protein that can regulate cell growth and division
Chromosomes become visable, nuclear envelop dissolves, spindle forms
Chromosomes line up in the middle of the cell
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Phase of mitosis in which a nuclear envelope reforms around each set of chromosomes.
a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
Division of the cytoplasm during cell division
A nuclear division resulting in the production of two somatic cells having the same genetic complement as the original cell.
Disorder in which some of the body's cells lose the ability to control growth
Stem cells with the potential to differentiate into any type of cell.
one of a group of external regulatory proteins that stimulate the growth and division of cells
Process in which cells become specialized in structure and function
An organism in the earliest stage of development
Programmed cell death
Cells that divide and remain undifferentiated. Three types are totipotent, pluripotent, and multi-potent.
A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Chromosomes that have the same sequence of genes and the same structure
(genetics) an organism or cell having two sets of chromosomes or twice the haploid number
(genetics) an organism or cell having only one complete set of chromosomes
structure containing four chromatids that forms during meiosis
Process in which homologous chromosomes exchange portions of their chromatids during meiosis.
A haploid cell such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote.
Law of Independent Assortment
Each member of a pair of homologous chromosomes separates independently of the members of other pairs so the results are random
Law of Segregation
Mendel's law that states that the pairs of homologous chromosomes separate in meiosis so that only one chromosome from each pair is present in each gamete
