Mitosis and Meiosis Review

Which phase of mitosis is depicted in this image?

• Cytokinesis

• Interphase

• Anaphase

• Metaphase

Which of the following does not occur by mitosis?

• growth

• production of gametes

• repair

• development of the embryo

Which best describes the process shown?

• mutation in which the DNA content of the gene is altered

• segregation of sister chromatids

• condensation and segregation of the alleles

• crossing-over in which alleles are exchanged

Which of the following best describes meiosis?

• It is carried out in all tissues that require cell replacement

• It occurs only in cells in the reproductive structures of an organism

• It happens in all of the tissues except the brain and spinal cord

• It is the first stage of mitosis

Is the final result of meiosis haploid or diploid?

• diploid

• haploid

Which phase of meiosis is shown in the picture?

• anaphase I

• anaphase II

• telophase I

• telophase II

In meiosis, crossing over occurs in prophase 1. What is the significance of this event?

• This process ensures that chromosomes are evenly divided into daughter cells.
• This process can lead to genetic variation in daughter cells.
• This process can create gaps in the chromosome DNA for RNA to bind.
• This process allows for spindles to connect to the chromosomes in order to pull chromosomes apart.

Which phrase best describes meiosis I?

• duplication of paired chromosomes

• division of sister chromatids

• division of homologous chromosomes

• creation of two diploid cells
