Exam 6: Cell Division

The last stage in the cell cycle is ________; this consists of ________,which separates the replicated DNA,and ________,which divides and portions the contents of the cell into two new daughter cells.

Homologous chromosomes

Sister chromatids are held together at a constriction point called a ________.

In genetic engineering,molecular biologists often combine segments of DNA from two separate organisms.This is an example of genetic recombination that occurs in a laboratory setting.Which of the following is a form of genetic recombination that occurs naturally within cells?

Which of the following statements is supported by the infographic shown below?

Design an experiment testing the hypothesis that increased exposure of a sexually reproducing population to BPA will result in an increase in the number of offspring who have an extra chromosome or who are missing one of their chromosomes.Use the following materials and abilities: BPA,a placebo,1,500 lab mice,and the ability to extract gametes from the mice and examine their chromosome number.Indicate in which phase of meiosis the error is most likely to occur.

Which term is best associated with a synapsed pair of homologous chromosomes?

A replicated chromosome consists of ________ sister chromatid(s).

The processes of mitosis,meiosis,and binary fission all

When everything proceeds without error,the process of ________ produces ________ daughter cells that are genetically identical to the mother cell,while the process of ________ produces ________ daughter cells that have half the genetic information present in the mother cell.

Which two processes work in conjunction to create genetic diversity and maintain chromosome number?

Cancers are groups of cells that divide rapidly and uncontrollably.Thus,cancer cells

Describe the two structures seen below.When would they most likely be present in the cell cycle?

Which of the following is NOT a factor that influences a cell's progression through the cell cycle?

Model organisms (like mice)used in the study of genetic disease

Which of the following is a difference between binary fission and mitosis?

What is the significance of crossing over?

Chromosomes are lined up at the middle of the cell during the ________ portion of cell division.

Which of the following foods is MOST likely to contain haploid cells?

Describe the G₀ phase of the cell cycle.Provide an example of what type of cell would enter the G₀ stage and propose why this cell would enter the G₀ phase.
