Question
Assignment 2 (cont'd), Spr'18 Name, please: -page 2 THI S PAGE MUST BE COMPLETED AS A WORKSHEET for 3 POINTS BUT IT WILL NOT BE GRADED The events below refer to a cell that undergoing meiosis. On each line, please write the NAME of the cell-cycle each of the following events occur. BE AS SPECIFIC AS POSSIBLE (e.g., metaphase I, anaphase lI, etc.) romosomes line up as pairs in the center of the cell separate sister chromatids to opposite ends of the cell Herophase 1. homologous ch 2. spindle fibers 3, four haploid daughter cells form 4. spindle fibers 5. two haploid daughter cells form 6. replicated chromosomes line up single file in the center of the cell 7. cell undergoes DNA replication 8. syna separate homologous chromosomes to opposite ends of the cell 9. Please write the correct order of the above events (write numbers only) :- 5 2 3 10. Compare the number and type of daughter cells that result from meiosis vs mitosis. cells ColIS 11. How do the genetic contents of daughter cells resulting from mitosis and meiosis differ? 12. How do the daughter cells at the end of meiosis II differ? 13. Please answer the following based on a diploid cell that has 102 chromosomes in G1 of interphase. How many pairs of homologous chromosomes are in the cell during G1? If the cell undergoes meiosis, how many chromosomes will be in the cell during metaphase 1? How many pairs of homologous chromosomes will be in the cell during metaphase 1? How many chromosomes will be in a daughter cell after meiosis I is completed? How many pairs of homologous chromosomes will be in a daughter cell after meiosis I is completed? How many chromosomes will be in a cell during metaphase lI? How many chromosomes will be a daughter cell after meiosis Il is completed? How many pairs of homologous chromosomes will be in a daughter cell after meiosis II is completed? Please read each statement below, then write on the line whether it applies to (a) mitosis, (b) meiosis I, (c) meiosis !I (d) both mitosis&meiosis; J(e) both mitosis & meiosis ll (f1 meiosis 1& Il,(8) all: mitosis, meiosis I & meiosis Il; also identify the specific stage of the cell cycle that applies (e-g, G1,S, G2, mitosis prophase, meiosis anaphase li, cytokinesis I, cytokinesis I, etc). 14. 15. 16. pairs of homologous chromosome line up across midline of the cell spindle fibers separate sister chromatids spindle fibers separate homologous chromosomes haploid daughter cells are produced chromosomes line up single file across the midline of the cell synapsis & crossing-over occurs diploid daughter cells form 18. 19. 20.Explanation / Answer
Answer 1) Homologous chromosomes line up as pairs in the center of the cell - Metaphase I
Answer 2) Spindle fibers separate sister chromatids to opposite ends of the cell - Anaphase II
Answer 3) Four haploid daughter cells form - Cytokinesis II
Answer 4) Spindle fibers separate homologous chromosomes to opposite ends of the cell - Anaphase I
Answer 5) Two haploid daughter cells form - Cytokinesis I
Answer 6) Replicated chromosomes line up single file in the center of the cell - Metaphase - II
Answer 7) Cell undergoes DNA replication - Interphase I
Answer 8) Synapsis and crossing over occurs - Prophase I
Answer 9) Correct order must be 7 8 1 4 5 6 2 3
