06. Cell Cycle

Cell Cycle

Cell Cycle The regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells
Interphase When the cell appears to be at rest during the cell cycle. DNA is copied during this phase ("in between" cell division)
Phases of Interphase Gap 0 (G0), Gap 1 (G1), Synthesis (S), and Gap 2 (G2)
G0, G1, G2 Stages of Interphase where the cells are growing
Chromosomes One long continuous thread of DNA that consists of numerous genes along with regulatory information
Chromatid One half of a duplicated chromosome
DNA Deoxyriboucleic Acid. Molecule that stores genetic information in all organisms.
Sister Chromatids Two identical chromatids held together by a centromere
Centromere Sister chromatids are held together here. ("Center" of a choromosome"
Spindle fibers Help align the chromosomes at the middle of the cell
Centrioles Help divide DNA during cell division by producing spindle fibers that attach to the DNA and pull it to one side of the cell.
Diploid (2n) Cell that has two copies of each chromosome, one from an egg and one from a sperm.
Full set of chromosomes Humans have 23 different chromosomes. Because we get one copy from our mother and one copy from our father we have 46 total chromosomes.
Cell division / Cell growth Cell division - a cell divides into 2 cells. Cell growth - a cell increases it's organelles and DNA before division.
Somatic cells Cell that makes up all of the body tissues and organs, except gametes
identical daughter cells Cells produced from cell division that are genetically identical to the parent cell
clone Genetically identical copy of a single gene or an entire organism
