Unit 3 List 2 Cell Cycle Flashcards
Anaphase
..the stage of the cell cycle in which duplicated chromosomes separate and move towards opposite poles of the cell
Cancer
diseases in which abnormal cells divide without control and can invade nearby tissues
Cancer Checkpoints
help keep immune responses from being too strong and sometimes can keep T cells from killing cancer cells
Cell Cycle
the name we give the process through which cells replicate and make two new cells
Cell Differentiation
The process during which young, immature (unspecialized) cells take on individual characteristics and reach their mature (specialized) form and function
Centrioles
paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope.
Centromere
the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division
Chromatid
one of the two identical halves of a chromosome that has been replicated in preparation for cell division.
Chromatin
A highly organized condensed structure made up of DNA, RNA, and proteins that forms the chromosomes in the nucleus of a cell
Chromosomes
a DNA molecule that contains the genetic information for an organism
Cytokinesis
divides the cytoplasm of a parental cell into two daughter cells
Interphase
the phase of the cell cycle in which a typical cell spends most of its life.
Metaphase
a stage during the process of cell division (mitosis or meiosis)
Mitosis
the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division
Nucleolus
An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made
Prophase
the first phase of mitosis
Stem Cells
They continuously renew and divide to make exact replicas of themselves
Telophase
the fifth and final phase of mitosis.
