cell cycle
| Question | Answer |
|---|---|
| what part of a chromosome directs the production of rna and protiens | gene segment |
| where do cells spend the most time in the cell cycle | interphase |
| how many checkpoints does the cell cycle have | three |
| name the three checkpoints o the cell cycle | G1 G2 mitosis |
| what are the three reasons cells divide | cell size cell matinence growth and repair |
| what is the purpouse/function of a centromere | to hold to sister chromatids together until ready to divide |
| what stage happens before G1 | cytokinesis |
| what is a chromatid | strands of duplicated gene |
| correct sequence of cell cycle | G1, S, G2, Mitosis, Cytokinisis |
| where does dna replication occur | S phase |
| how many steps are in mitosis | Four |
| name the steps of mitosis | prophase metaphase anaphase telophase |
| what are the first three phases of cell cycle known as | interphase |
| what phase are chromosomes lined up in the middle of the cell | metaphase |
| what phase does a nuclear membrane form around dna | telophase |
| what phase does the nuclear membrane disappear | prophase |
| what phase do the sister chromosomes separate and are pulled to opposite poles | anaphase |
| what is cell division controlled by in eukaryote cells | proteins signals from surrounds cells and organs environmental changes |
| what happens to normal cells in the cell cycle that causes them to be cancer cells | cells ignore checkpoints |
| when then cell is about to divide dna is packed into coiled structures called | chromosomes |
| sequence of events that occurs from one cell division to the next | cell cycle |
| what is happening in G1 | cell grows and builds organelles |
| what happens in the S phase | dna is copied |
| what happens in G2 | cell grows and prepares to divide |
| what happens to the nucleus in mitosis | forms daughter nuclei |
| how many daughter cells are made in mitosis | Two |
| what happens in cytokinesis | division of cytoplasm |
