Homework Answers
The microarray is a technique in which several microscopic DNA
spots are fixed on a solid surface.
These spots are used to measure the levels of expressed genes of
multiple regions of a genome in
different conditions.
So option D is correct.

Northern blotting, RT-PCR, and microarrays can be used to analyze gene expression. A lab studies yeast cells, comparing their growth in two different sugars, glucose and galactose. One student is comparing expression of the gene HMG2 under these two conditions. Which technique(s) could he use and why? Another student wants to compare expression of all the genes on chromosome 4, of which there are approximately 800. What technique(s) could she use and why?

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

please answer all the question to get a like. Part III Dr. Hernandez sits down with Ann and her partner. The doctor is sorry to report that Ann has breast cancer; however, because it was caught early and responds to estrogen and progesterone, the prognosis is good. At this point it looks like the cancer is stage 1. However, as Ann is young, the doctor wants to perform a couple of tests. The first test is a genetic sequencing test...

Explain the following in terms a highschooler would understand (from article Expression of HoxD Genes in Developing and Regenerating Axolotl Limbs, 1998): DISCUSSION: Expression of HoxD genes in developing axolotl limb buds. We have examined the expression of Hoxd-8, Hoxd10, and Hoxd-11 genes in axolotl limb buds and find many similarities between the patterns of expression in axolotls and those described for other vertebrates. Similarities are most pronounced in phases I and II (Nelson et al., 1996; Shubin et al.,...

What genes (or kind of genes) will you focus on in your investigative research? Provide 2-3 reasons for your choice of these gene/s. Starting with the bone sample itself, what methods will you use to get DNA that you can sequence? Which “ingredients” in your lab reactions will determine which gene or genes are copied? How is it that these ingredients are able to target a specific gene? What method will you use to see if your efforts to copy...
