| Question | Answer |
| DNA is wound around | a nucleosome which is made of 8 histone proteins |
| during interphase chromosomes are called | chromatin |
| somatic cells | are ordinary diploid cells |
| to stain chromosomes use | acridine orange |
| all an individuals chromosomes is called | a karyogram |
| number of autosomes in humans | 22 pairs in each diploid cell |
| in humans meiosis produces | 23 chromosomes |
| in humans mitosis produces | 46 chromosomes |
| functions of mitosis are | reproduction, growth and tissue repair |
| prokaryotic mitosis is called | Binary fission |
| if cytokinesis does not occur | a coenocyte forms |
| Gastrulation | a process in which an embryo develops into a cup shaped structure with a cavity( occurs in fruit fly larvae) |
| Gametogenesis | formation of gametes |
| metamorphosis | adult emerges from pupa |
| the stages of interphase are | G1,G0,S and G2 |
| during the G1 stage of interphase | organelles are doubled |
| the G0 stage of interphase | refers to permanently resting cells such as nerve or muscle |
| during the S stage of interphase | the genome of the cell is replicated |
| during the G2 stage of interphase | proteins needed in cell division are made |
| Centrosomes | contain a centriole pair |
| kinetochore protein | attaches to chromatids so as they can move easily |
| at the end of telophase | a clevage furrow forms |
| during prophase 1 of meiosis | crossing over occurs at chiasmata |
| crossing over leads to | variation |
| in metaphase 1 of meiosis | homologous chromosomes line up on the equator of the cell |
| in metaphase 2 of meiosis | sister chromatids line up on the equator of the cell( same as mitosis) |
