Question

13. Prokaryote such as bacterial undergo division by which of these division A. Binary fission B. Meiosis C. Mitosis D. A and C E. B and C 14. Both eukaryotes and prokaryrotes have nuclei. True ( A) or False (B) 15. During mitosis, four identical cells are produced, while in meiosis, two unidentical cells are produced. True (A) or False (B) 16. In which of the phases of meiosis does crossing over or synapsis occurs? A. Prophase I B Metaphase I C. Prophase I D. Anaphase I E. Anaphase II

Answer 1

13. binary fission

Prokaryotes such as bacteria propagate by binary fission. For unicellular organisms, cell division is the only method to produce new individuals.

14. False

The distinction is that eukaryotic cells have a "true"nucleus containing their DNA, whereas prokaryoticcells do not have a nucleus.

15. False

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

16. Prophase I

Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
