Mitosis/CellCycl A.T
Mitosis/
| Question | Answer |
|---|---|
| What is a chromosome? | packages of DNA and proteins |
| How many Chromosomes do humans have? | 46 chromosomes |
| How many pairs of chromosomes do they have? | 23 pairs |
| What is the first phase of the cell cycle ? | G1 Phase |
| What are the phases in the cell cycle called? | Stages of Interphase |
| What happens in the G1 Phase? | Growth |
| What happens in the M phase ? | Mitosis and Cytokinesis |
| Which three hases make up interphase? | G1,S, G2 |
| The division of the cell nucleus during M phase of the cell cycle is called? | Mitosis |
| What stage is it when Chromosomes are replicated and the synthesis of DNA molecules take place? | S phase |
| Phase in which mitosis and cytokinesis occurs? | M phase |
| G1 . S, G2 phases all make up what phase? | Interphase |
| In eukaryotic cells chromosomes are what shape? | Linear |
| In prokaryotic cell chromosomes are what shape? | Circular |
| mitosis? | is cell division from making two identical nuclei. |
| The order of phases? | Interphase, prophase, metaphase, anaphase, telophase and cytokinesis. |
| Occurs in what type of cells? | Somatic Cells |
| What does Mitosis produce? | 2 genetically identical cells |
| What does Cytokinesis do? | It completes the mitosis process by dividing the cytoplasm |
| How many stages make up Mitosis? | About 4 |
| What are the four stages of Mitosis in order? | Prophase, Metaphase, Anaphase, and Telephase |
| What happens in anaphase? | The chromosomes are separated and move to opposite sides of the cell |
| What happens in Prophase? | Chromatin condenses to form chromosomes. The nucleus breaks down and spindle fibers begin to form. |
| What occurs during the stage of metaphase? | Chromosomes line up in the center. |
| What occurs during the telephase stage? | Chromosomes begin to separate. The nucleus begins to form and the spindle fibers break down. |
