Cell Cycle A&P1 lab
| Question | Answer |
|---|---|
| very early embryonic cells | stem cells |
| normal body (somatic) cell & number of chromosomes | diploid, 46 |
| egg & sperm cells | haploid, have only half the nomral chromosomes (23) |
| sequence of events that occurs during life of a cell | cell cycle |
| metabolically active, duplicates organelles & cystolic components,replicates centrosomes | G1 Phase |
| what happens during G1 phase? Time length? | grows, longest phase, days to years depending on cell type. metabolically active, duplicates organelles & cystolic components,replicates centrosomes |
| programmed cellular death | apoptosis |
| dormant state in which cells only perform necessary functions to stay alive | G0 phase. time varies |
| commitment to undergo cellular division. DNA replicated | **S Phase |
| **S Phase | DNA replicated during |
| organelles duplicated, final opportunity to create proteins | G2 Phase |
| Interphase schedule | G1, G0, S, G2 (M) |
| exit from cell cycle-nondividing cell | G0 |
| g2 phase | cell growth continues, enzymes & other proteins synthesized, replication of centrosome completed. |
| Mitotic(M) Phase cycle | Prophase, Metaphase, Anaphase, Telophase |
| cellular division produces | 2 identical daughter cells during Mitosis |
| rate at which cell undergoes Mitosis | Mitotic rate |
| Interphase activities (3) | DNA replication, duplicated organelles, cell growth |
| What happens during prophase | nuclear membrane disappears, distinct chromosomes |
| copies of chromosome DNA | chromatid |
| chromatids held together by a | centromere |
| astral ray of spindle fibers | microtubules extend between pairs of centrioles |
| metaphase | equator, chromosomes line up *countable |
| anaphase | centromere divides & chromatids seperate moving towards centrioles at opposite poles- pulled apart by spindle fibers |
| Mitotic(M) Phase cycle | Prophase, Metaphase, Anaphase, Telophase |
| telophase | 2 identical daughter cells during Mitosis |
| rate at which cell undergoes Mitosis | Mitotic rate |
| Interphase activities (3) | DNA replication, duplicated organelles, cell growth |
| prophase | active cell division |
| What happens during prophase | nuclear membrane disappears, distinct chromosomes |
| copies of chromosome DNA | chromatid |
| chromatids held together by a | centromere |
| astral ray of spindle fibers | microtubules extend between pairs of centrioles |
| metaphase | equator, chromosomes line up *countable |
| anaphase | centromere divides & chromatids seperate moving towards centrioles at opposite poles- pulled apart by spindle fibers |
| cellulr components physically seperated (hour-glass) | cytokinesis |
| telophase | chromosomes finish moving to daughter cells, DNA uncoils, nuclear envelope reforms, |
| what follows telophase | interphase and G0 |
| prophase | active cell division, chromosomes become visible |
