Anaphase
Which stage of mitosis does this image represent? The spindle fibers pull the chromatids apart and pull them to opposite poles. This gives rise to daughter chromosomes
Metaphase
Which stage of mitosis does this image represent? Chromosomes line up along the equator in the middle of the cell
Prophase
Which stage of mitosis does this image represent? Nuclear membrane disappears / Chromatin condenses and thickens into chromosomes / Spindle fibers appear
Telophase
Which stage of mitosis does this image represent? Nuclear membrane forms around each set of chromosomes / Spindle fibers disappear / Chromosomes return to there original, uncondensed chromatin form
Interphase
Time period between cell divisions when the cell grows, DNA duplicates and preparation for mitosis occurs. "Your in _________ when you grow"
Mitosis
Division of the nucleus, creates two identical daughter cells.
Cytokinesis
Division of the cytoplasm and organelles
Two Daughter Cells
End result of mitosis; two cells that are identical (copies)
BRCA1
Best-known gene linked to breast cancer risk. Everyone has these genes, but some people have an inherited mutation in one or both that increases the risk of breast cancer.
Chromosome
Strand of coiled DNA that is encoded with genes. In most cells, humans have 23 pairs.
Cell Differentiation
Over 250 different cells in the human body, caused by expression of different genes in different types of cells
Gene
A linear sequence of nucleotides along a segment of DNA that codes for a physical trait of characteristic
Mutations
Some changes in the genetic code that affect the function of the gene. Rare.
Benign
Tumor cells grow only locally and cannot spread by invasion or metastasis
Gametes
Specialized sex cells produced by each parent for reproduction; sperm & egg in humans
Stem Cells
Undifferentiated cells which can develop into many different cell types.
Mestastatic
Cancer that has spread from one part of the body where it started (the primary site) to other parts of the body.
Malignant
Cells invade neighboring tissues, enter blood vessels, and metastasize to different sites.
Tumor
A cancerous mass
Tumor Suppressor Genes
Active in normal cells, work to prevent uncontrolled cell growth.
Oncogenes
A gene that has the potential to cause cancer.
DNA
Contains the genetic "blueprint" or "code" for life. Deoxyribose Nucelic Acid.
Cell Cycle
You're in interphase when you grow, you're in interphase, until DNA starts to replicate. (The mitosis....your cells divide)
Cell Division
Process by which a parent cell divides into two identical daughter cells.
Meiosis
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 (sperm & egg in sexually reproducing) and plant spores.
Genetic variation
Differences among individuals in the composition of their genes or other DNA segments
Protein
An organic compound that is made of one or more chains of amino acids and that is a principal component of all cells
