Question | Answer |

The cell is divided into what three parts? | Cell & growth activity, replication on DNA (Mitosis), & division of cytoplasm (cytokinesis). |
What is Mitosis? | Divides the replicated DNA equaly and precisely, generating daughter cells which are exact gnetic copies of parent cell. |
What is meiosis? | Produces daughter nuclei with half of the number of chromosomes in the parent nucleus. |
The number of chromosome sets in a cell or species are called what? | Ploidy |
If a cell has only one copy of chromosome it is-- | Haploid or n |
If a cell has three or more copies of chromosome it is -- | Polyploid |
If a cell has two copies of chromosome it is-- | diploid or 2n |
The two chromosome pairs in diploid cell are called-- | Homologous chromosomes |
Before a cell divides, duplication of each chromosome produces two identical copies called-- | sister chromatids |
The equal distrubrition of the chromosomes into each of the daughter nuclei is called-- | Chromosome segregation |
What are the three main events in a cell called? | Interphase, Mitosis, and Cytokinesis. |
Interphase is divided into what three parts? | G1 phase- Cell grows S phase- DNA replicates G2 phase- Cell growth continues |
Mitosis is broken down into what five parts? | Prophase, Prometaphase, Metaphase, Anaphase, & Telophase |
Cytokinesis produces what? | Two daughter cells |
In animal cells, cytokinesis occurs by forming what? | Furrow |
In plant cells, cytokinesis occurs by forming what? | A cell plate |
When is mitotic cell cycle used? | Growth of multicellular eukaryotes from a fertilized egg to fully developed adults |
