Cell Divide
All of living things are made of
What are cells?
The life of a cell is
What is cell cycle?
These two types of cell division.
What is mitosis & meiosis?
The production of haploid daughter cells with unique combination of genetic information.
What is recombination?
code for proteins that promote cell growth & division.
What is proto-oncogenes?
Cells divide for 3 important reasons:
What are growth,repair,& reproduction
Interphase is divided into three phases:
What is G1 phase, S phase, & G2 phase?
Mitosis & Meiosis have 5 phases.
What is prophase,metaphase,anaphase, telophase, and cyotkinesis?
The chance that an allele will separate and sort into a daughter cell with other alleles on different chromosomes is completely random.
What is independent assortment?
code for proteins that inhibit cell growth & division
What is tumor suppressor genes?
The cells of an organism divide, the number of cells in the organism increases, making the organism bigger.
The cell increases in size & produces new organelles and proteins
What is G1 phase?
The nuclear membrane breaks down and chromosomes condense.The chromosomes line up single file.
What is prophase & metaphase?
When the chromosomes pair up, the sister chromatids of homologous chromosomes can cross. When the sister chromatids cross each other,they exchange portions of their genetic information.
What is crossing over?
Sometimes cells lose the ability to control cell growth and division.
What is cancer?
Cells make copies of themselves to replace damage cell.
What is repair?
Chromosomes replicate and the chromosomes remain attached to each other at a region called the centromere.Each identical replicated chromosome is called a chromatid.
What is S phase?
The individual chromosomes move to opposite sides of the cell.
What is anaphase?
Sometimes mistakes happen during meiosis. Mistakes during cell division often cause chromosome abnormalities.
What is nondisjunction?
The cells are abnormal, but they do not invade neighboring tissues and they usually grow slowly.
What is benign tumor?
the production of an offspring
Organelles replicate and molecules needed for cell division are produced; the shortest phase of interphase.
What is G2 phase?
Cytoplasm divides,have two cells.
What is telophase & cytokinesis?
The most common human chromosome abnormality.
What is Down Syndrome?
cancer cells that invade and destroy neighboring tissue.
What is malignant tumor?
