Chapter 11 - Mitosis Flashcards
Cell cycle
A series of events from the time a cell forms until it’s cytoplasm divides
Asexual reproduction
Reproduction mode by which offspring arise from a single parent cell
Homologous chromosomes
Chromosomes with the same length, shape, and set of genes
Interphase
In a eukaryotic cell cycle the interval between mitotic divisions when a cell enlarges, roughly doubles the number of its cytoplasmic components and replicates its DNA
Mitosis
Nuclear division mechanism that maintains the chromosomal number. Basis of body growth and tissue repair in multi-celled eukaryotes, also asexual reproduction in some plants, animals, fungi, and protista
Prophase
Stage of mitosis during which chromosomes condense and become attached to a newly forming spindle
Metaphase
Stage of mitosis at which cell’s chromosomes aligned midway between poles of the spindle
Anaphase
Stage of mitosis during which sister chromatids separate and move to opposite spindle poles
Telophase
Stage of mitosis during which chromosomes arrive at the spindle poles and deco de se, and new nuclei form
Spindle
Dynamically assembled and disassembled network of microtubules that move chromosomes during nuclear division
Cell plate
After nuclear division in a plant cell, a disk-shaped structure that dorms a cross-wall between the two new nuclei
Cleavage furrow
In a dividing animal cell, the indentation where cytoplasmic division will occur
Cytokinesis
Cytoplasmic division
Telomere
Noncoding, repetitive DNA sequence at the end of chromosomes, protects the coding sequences from degradation
Growth factor
Molecule that stimulates mitosis and differentiation
