Proteins that are involved in the regulation of the cell cycle, and that show fluctuation in concentration during the cell cycle, are called ________. (Points : 4) centromeres
kinetochores
centrioles
cyclins
proton pumps


 


 


All of the following statements are true about mitosis except (Points : 4) the cells arising from the process all have half of the genetic material.
the cells arising from the process are genetically alike.
the process of mitosis is followed by cytokinesis.
spindle fibers are involved in the movement of chromosomes.
both sexually and asexually reproducing organisms utilize the process of mitosis


 


 


Which of the following statements is correct regarding the events of the cell cycle? (Points : 4) DNA is duplicated during the G1 and G2 phases
DNA replicates during cytokinesis.
Interphase consists of G1, S, and G2.
The M phase is usually the longest phase.
The cell stops growing in G2 phase.


 


One major difference between meiosis I and meiosis II is that (Points : 4) crossing over occurs in prophase of meiosis I but not in prophase of meiosis II.
sister chromatids are separated during meiosis I while homologous chromosomes are separated during meiosis II
the resulting cells at the end of meiosis I are diploid while the cells at the end of meiosis II are haploid.
in telophase of meiosis I four daughter cells form from the parent cell and in telophase of meiosis II each parent cells gives rise to two daughter cells.
in meiosis I there is no pairing of chromosomes while homologues pair in meiosis II.


 


A tetrad is composed of (Points : 4) two chromosomes with two sister chromatids each.
