| Question | Answer |
|---|---|
| What are the 4 main stages of the cell cycle ? | Gap 1 , Synthesis , Gap 2 , mitosis |
| Why is cell size limited ? | If the cell is too small it won't contain all necessary organelles and molecules . If it gets too big it'll cause surface area too small for adequate exchange of materials. |
| Why are your cells divided at different rates ? | Divided to link to your body's needs fro cells. |
| Why do some cells have to be large ? | The structure gives the neuron large surface area with relatively small increase in volume. |
| What is a chromosome ? | It's a long continuous thread of DNA consists of numerous genes along with regulatory information. |
| Why do chromosomes condense at the start of mitosis ? | To carry out its necessary functions. |
| What's a histones function ? | DNA wraps around ti at regular intervals to interact with each other , further compacting the DNA. |
| What does the mitosis cell do ? | Divides cells nucleus into two genetically identical nuclei , which forms eggs and sperm that prepares them for cytokinesis. |
| What does the interphase cell do ? | It provides critical time and it becomes larger to divide. |
| What is cytokinesis ? | Divides cytoplasm into two cells which differs in animal and plant cells. |
| What is prophase ? | The nuclear envelope breaks down. the nucleolus disappears , and the centrosomes centrioles migrate to opposie sides. |
| How many stages does the cell cycle have ? | The cell cycle has 9 stages . |
| What is telophase ? | A complete set of identical chromosome positioned at each pole of cell. |
| Why do spindle fibers attach to a protein structure in metaphase? | To align the chromosomes along the cell equator , around the middle of the cell. |
| What happens during anaphase ? | Sister chromatids separate from each other. |
