Use graph key as guide A cell mitosis experiment in which the cells count is determined hourly over a 24 hour period is shown below: Growth curve: sruck What conclusions can you draw about the process of mitosis over a 24-hour period? Lines: Individual

In your own words, describe Flow Cytometry and how it is used to study the cell cycle.

Which of the following options correctly describes the functions of both cilia and flagella? Excretion   Protection   Locomotion       Body’s defense       BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring?      Random alignment increases the likelihood of crossing over between non-sister chromatids.   Random alignment results in the formation of gametes that contain different numbers of chromosomes.   Random alignment increases the number of possible chromosome combinations in the gametes.   Random alignment results in the formation of some diploid and some haploid gametes.

Describe the three most important cell cycle checkpoints. Explain in a detailed manner and provide some sample scenarios.

Which event occurs in S-phase? Question 4 options:   Mitotic spindle is created.   Normal growth and cell function   Energy stores are replenished   Karyokinesis   None of the above

The assembly and function of the mitotic spindle depend on numerous microtubule-dependent motor proteins. In the mitotic spindle, these motor proteins generally operate at or near the ends of the microtubules. Four major types of motor proteins are:

Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle. Match each label to the correct locationn in the model. (use photo to know where  they be put)   ITEM BANK: Move to Bottom Cell double checks duplicated material for errors. Cellular contents excluding chromosomes are duplicated. Chromosomes are duplicated. Genetic material divided and 2 daughter cells form.   not graded

Count 100 cells and tally them. Remember the phases you learned in Bio 31 and Anatomy? Draw a pie chart graph showing the phases of Allium root tip. Label each of the phases with the % for each phase: prophase metaphase anaphase  telophase interphase provide direction of the phase progression--direction in which to read the graph so the phases of mitosis are in proper order.

A cell stops proliferating when treated with a chemical analog to fucoxanthin. When these cells are analyzed and compared to untreated cells according to the amount of DNA they contain using flow cytometry, the graphs in the figure below are obtained. Which of the following answers would NOT cause this result?

Match the image with each phase of the cell cycle.
