Summary Introduction

To write:

The benefits of DNA microarray over genetic markers.

Introduction:

Lately, the diseases related to faulty genes have been on a rise. This is seen not only in congenital diseases but cancer too. Thus many procedures have been developed to screen these like DNA microarray, genetic markers and more.

Expert Solution & Answer
Check Mark

Explanation of Solution

When genetic markers are used for genetic testing, certain types of nucleotide sequences are searched for and the differences that have arisen in them like STRs (short tandem repeat sequences). For example: An abnormally long STRs could cause a frame-shift mutation. The results are amplified via PCR. Particular diseases (mutation) can be searched for.

In DNA microarray, the complete genome can be tested at ones. The DNA is labeled with fluorescent dyes and put onto the microarray plate which contains allele for mutations. If mutations are present in the genome, the part will bind to the plate and emit fluorescence. Thus, the disease(s) are screened. Herein, multiple diseases can be screened at ones and does not have to be amplified.

Thus, DNA microarray screens for many diseases at ones unlike genetic markers and also takes lesser time. Moreover, the complete DNA microarray procedure is automated, so the chances of human error are minimal.

Conclusion

DNA microarrays are faster and more efficient than genetic markers as they test for multiple diseases at ones and is completely automated.

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…
