Scy Exam test 10

• The cell cycle is G1 S G2 M
• G1-growth
• S- copying of DNA
• G2-growth (again)
• M-mitosis (PMAT) (G1-G2 is interphase)

• somatic cells are-(diploid) are any cells forming the body of an organism
• 46 Chromosomes

• Diploid- has all of the chromosomes
• Haploid- has half of the chromosomes

• 4
• Prophase
• Metephase
• Anaphase
• Telophase

Centrioles-A self-replicating, small, fibrous, cylindrical-shaped organelle, typically located in the cytoplasm near the nucleus in cells of most animals. It is involved in the process of nuclear division.

spindle fibers-Any of a network of filaments that collectively form a mitotic spindle (in mitosis) and meiotic spindle (in meiosis). It is chiefly involved in moving and segregating the chromosomes during nuclear division.

centromeres-he constricted region joining the two sister chromatids that make up an X-shaped chromosome.

• Prophase-nucleus starts to fade and centrioles and spindler fibers start to appear and chromosomes start to become visible
• Metephase- chromosomes line up in the middle of the cell
• Anaphase-Chromatids seperate to opposite sides of the cell
• Telophase-cell starts to split, spindle fibers and centrioles start to dissapear and nuclues starts to reappear.

• 1. one of a pair of chromosomes
• 2. a chromosome with the same gene sequence as another

The division of the cytoplasm and the plasma membrane following the division of the nucleus resulting into two cells, each having its own nucleus and cytoplasm surrounded by a plasma membrane.

as Mrs. Corbett would say, free answer (smiley face)

on test numbe 10, look at questions 2, 4, 6, 8, 25
