Question Answer
What is the cell cycle Regular pattern of growth, DNA duplication and cell division that occurs in eukaryotic cells
What are the 4 main stages of the cell cycle Gap 1, synthesis, gap 2, and mitosis
What is Gap 1 The first stage of the cell cycle, a cell carries out it's normal functions
What is synthesis Second stage of the cell cycle, the cell makes a copy of it's nuclear DNA
What is Gap 2 Third stage of the cell cycle, cells continue to carry out their normal functions, and more growth
What is mitosis The fourth stage of the cell cycle, nuclear membrane dissolves, the duplicated DNA condenses around proteins and separates and two new nuclei form
Do cells divide at the same time No, the rate at which your cells divide is linked to your body's need for those cells
What is DNA like during mitosis Chromosomes are tightly condensed
What is DNA like interphase DNA is loosely organized like spaghetti
What are the four stages stages of Mitosis Prophase, Metaphase, Anaphase, telophase
What happens during Prophase Chromatin condenses tightly coiled chromosomes each consist of 2 identical twins
What happens during Metaphase Spindle fibers attach to a protein stucture
What happens during telophase Sister chromatids separate from eachother
What happens during telophase A complete set of identical chromosomes is positioned pf each pole of a cell
What is cytokinesis The division of the contents of the rest of the cell-the cytoplasm
What is a chromosomes One long piece of DNA
What is chromatid Each half of a duplicated chromosome
What is centromere Where the sister chromatids are held together
What are histones a protein DNA wraps around
What are reasons your body cells need to divide to repair, development, and growth
