Summary Introduction

To review:

The investigators studying the protein changes during aging examined the enzyme activity in the cells extracted from the Caenorhabditis elegans, a nematode worm. The cell extracts were then treated to conserve the enzymatic activity. Although, the investigators noted that some of the proteins were broken down by the process of extraction. The centrifugation of the extracts was performed and seven fractions were collected for isolating the location of the protease enzyme activity, the enzyme called cathepsins. The fraction and the eukaryotic cellular structure in which the enzymatic activity is most active.

Introduction:

The Caenorhabditis elegans is a transparent nematode, which is free-living and it is approximately 1mm (millimeter) in length. It resides mostly in the temperate soil environments. It is the unsegmented pseudocoelomate and also does not have respiratory systems. The males have a special tail and spicules are present on the tail for mating purpose.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
