CELL CYCLE
| Question | Answer |
|---|---|
| In Human somatic (body) cells, how many chromosomes are from mom/dad?. how many are there total? | 23 from mom 23 from dad 46 chromosomes total. |
| how many chromosomes are in the human reproductive cells? | 23 chromosomes |
| what is a Chromatin? | DNA and its associated proteins |
| The life cycle of a cell is divided into several phases. What are the two phrases and their sub-phases | Interphase: G1, S, G2 Mitosis: Prophase, Metaphase, Anaphase, Telophase/Cytokniesis |
| What happens during Interpharse G1 | Cell Growth |
| What happens during Interpharse S pharse. what does S stand for? | S= synthesis Duplication of all the chromosomes |
| What happens during Interpharse G2 | Growth and preparation for cell division |
| what are the four steps of mitosis? (Please Move Across The Cell) | Phrophase, Metaphase, Anaphase, Telephase/Cytokiniesis |
| chromosomes are tightly packed, Nuclear membrane breaks down, centrosomes move to the opposite ends of cell, and microtubules entend out from the centrosomes to form spindles. What phase is this in mitosis? | Prophase |
| Chromosomes line up between the centrosomes. what phase is this in mitosis? | Metaphase |
| Sister chromatids are pulled apart towards centrosomes. which phrase is this in mitosis? | Anaphase |
| What happens during telephase? What happens during Cytokinesis? | Telophase: Nuclei form around chromosomes Chromosomes stare to unpack Cytokinesis: the cell split into 2 cells |
| what is Binary Fission (Cell Division) in Prokaryotes? | "division in half" Prokaryotes (single cell organism) can undergo a type of reproduction in which the cell grows to roughly doubles it size and then divides to form two cells. |
| Cells that no longer have functional checkpoints, and thus divide out of control. this unfortunate coinsurance leads to the development to what? | cancer |
| What is Benign tumor? hint: large amount | A mass of abnormal cells |
| What is a malignant tumor? Hint: neighboring | A tumor that invades neighboring tissue and impairs organ function. |
| what is metastatic tumor? Hint: Broke off | A tumor formed in another part of the body that formed from cells which broke off the original tumor. |
