What are the 4 main stages of the Cell Cycle? | Gap 1 (G1), Synthesis (S), Gap 2 (G2), and Mitosis |
During Prophase..... | Chromatin condenses into tightly coiled chromosomes. |
During Metaphase..... | Spindle fibers attach to a protein structure. |
During Anaphase..... | Sister chromatins separate from each other. |
During Telophase..... | Set of identical chromosomes. |
What does these 4 stages do? | G1: Carries out the normal functions S: Combining parts to make a whole chromosome. G2: Adds additional growth to the cell. Mitosis: The division of the cell nucleus and its content. |
What is the Cell Cycle? | pattern of growth, DNA, and cell division that occurs in a eukaryotic cell. |
What is a Chromosome? | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. |
What is Chromatin? | the material of which the chromosomes of organisms other than bacteria? |
What are Histones? | any of a group of basic proteins found in chromatin. |
What is Centromere? | the region of a chromosome to which the microtubules of the spindle attach. |
What are Telomeres | a compound structure at the end of a chromosome. |
What is Mitosis? | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
What is Cytokensis? | the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. |
What is DNA | A self-replicating material present in nearly all living organisms as the main constituent of chromosomes. |
