Question

a(n) is a gene, that typically ensures that cells are regulated properly before passing the checkpoint. however, when these genes are mutated, the likelihood of cancer increases. proto - oncogene tumor suppressor gene gap gene oncogene
8 multiple choice 1 point which of these is not a unique feature of meiosis? diploid daughter cells haploid daughter cells reduction division synapsis
9 multiple choice 1 point cells that do not normally divide spend most of their lives in the ___ phase of the cell cycle. m g0 g1 g2
10 multiple choice 1 point in which type of cell division does a cell create a clone (genetically identical copy) of itself? spermatogenesis meiosis mitosis oogenesis

Explanation:

• Question 8: Meiosis results in haploid daughter cells (not diploid). It involves reduction division (halving chromosome number) and synapsis (pairing of homologous chromosomes).
• Question 9: Cells that don't divide are in G0 phase. M is mitosis, G1 and G2 are growth phases before and after DNA synthesis.
• Question 10: Mitosis produces genetically identical daughter cells (clone). Spermatogenesis and oogenesis (types of meiosis) produce gametes with half chromosomes. Meiosis introduces genetic variation.

Answer:

1. Diploid daughter cells
2. G0
3. mitosis
