Genetics Question 23
Step by step
Solved in 3 steps
- QUESTION 8 Match the stages of mitotic cell division to the descriptions of those stages. ]chromosomes attach to spindle fibers across the middle of the cell chromosomes are not yet duplicated so chromosomes only look like a line, Jonly one pair of centrioles in cell A. Cytokinesis cell membrane is pinching in forming a peanut-shaped cell, daughter chromosomes reach the poles and new nuclear membranes are forming around them B. Anaphase C. Telophase D. Early Interphase the nuclear membrane is breaking down, chromosomes are condensing, centrioles are building microtubule "highways" (spindle fibers) E. Prophase chromosomes are duplicated so chromosomes look like an "X", two pairs of centrioles and double the amount of organelles fill the cell F. Late Interphase cell is dividing into two identical cells G. Metaphase daughter chromosomes are beginning their migration to the poles on spindle fibersQuestion 42 Which statement is true about mitosis? Page 1 (1E O It is a form of asexual reproduction resulting in daughter cells that each have half the number of chromosomes as the parent cell. O It is a form of asexual reproduction resulting in daughter cells that each have one set of chromosomes identical to the parent cell. O l is a form of sexual reproduction resulting in daughter cells that cach have one set of chromosomes identical to the parent cell.

- QUESTION 48 With regard to the process of mitosis, which of the following pairs is NOT matched correctly? Oa. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the cell to divide b. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell d. Anaphase - sister chromatids separate e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesisQUESTION 3 Lysogeny: happens when phage DNA is incorporated into the host cell genome happens when the burst time is unusually long involves the lysis of the host cell is the period during replicaiton when virions are not present O O O OQuestion: 1 Explain why the following statements are false and reword them to be true, regarding meiosis or mitosis. 1. Sister chromatids are always identical copies of each other. 2. Each pair of sister chromatids attaches to one of the two centromeres during prometaphase. 3.

- QUESTION 25 To visualize and identify meiotic cells at metaphase I with a microscope, what would you look for? O a. sister chromatids of a replicated chromosome grouped at the poles O b. individual chromosomes all at the cell's center O c. an uninterrupted spindle array Od. pairs of homologous chromosomes all aligned at the cell's centerQUESTION 5 Which of the following puts the stages of mitotic cell division in the order that they happen in? anaphase, cytokinesis, interphase, metaphase, prophase, telophase O A. interphase, prophase, metaphase, anaphase, telophase, cytokinesis O B. cytokinesis, prophase, metaphase, anaphase, telophase, interphase O D. interphase, metaphase, anaphase, prophase, telophase, cytokinesis QUESTION 6 What would be the result of a mitotic cell division of a cell with 46 chromosomes? A. a cell with 92 chromosomes B. two cells with 46 chromosomes each C. two cells with 23 chromosomes each D. four cells with 23 chromosomes eachQUESTION 34 Dynosaur inhibits the attachment of the microtubule motor protein dynein to microtubules. What will happen to the mitotic spindle positioning and chromosome segregation if Dynosaur is added at the start of prophase and present through the end of cytokinesis? Mitotic spindle positioning and chromosome segregation will proceed normally. The mitotic spindle would no longer be anchored to the plasma membrane and chromosomes might not be equally distributed between the daughter cells following anaphase. The centrosomes will be pulled more strongly towards the plasma membrane and chromosome segregation would be unaffected. The mitotic spindle would disintegrate, and chromosomes will become randomly positioned all throughout the dividing cell.
