Microarray quiz

07/01/2021 Client: saad24vbs Deadline: 10 Days

Question 1


Most scientists who use DNA microarrays obtain them





from companies that mass produce them






from the government






by making them in their labs






by exploiting ambitious graduate students


4 points


Question 2


"In this study, cancerous and normal skin tissue samples were excised with a scalpel. Each skin sample was then placed into a sample tube along with solvent, shaken on a vortex and centrifuged. When the sample tubes came out of the centrifuge, there was a top layer and a bottom layer. For our purposes, we went on to use ______________ for further processing."





only the top layer






only the bottom layer






a mixture of top and bottom layers






none of the options listed


4 points


Question 3


The purpose of the vortex instrument is to





vigorously shake the tissue sample in the solvent so that it dissolves.






spin the tissue/solvent mixture around to separate the solids






cause the mRNA to bind to the pellets






dispose of biohazardous waste safely


3 points


Question 4


"Once the RNA is isolated from the DNA, proteins and other materials, the solvent/RNA mixture is run through a column of all beads. Each bead has several short strands of polyT RNA sticking out of it. In this step:"





"mRNA sticks to the beads, while rRNA and tRNA run right through the column"






"tRNA sticks to the beads, while mRNA and rRNA run right through the column"






"rRNA and tRNA stick to the beads, while mRNA runs right through the column"






none of the options listed


4 points


Question 5


"Once the mRNA is isolated, you make a DNA copy of it using by adding polyT primers, labeled DNA nucleotides, and an enzyme known as:"





reverse transcriptase






tyrosine hydroxylase






alcohol dehydrogenase






ATP kinase


4 points


Question 6


A DNA copy of a mRNA transcript is known as





complementary DNA (abbreviated cDNA)






copied DNA (abbreviated cDNA)






mitochondrial DNA (abbreviated mtDNA)






recombinant DNA (abbreviated rDNA)


3 points


Question 7


Each spot on the DNA microarray in embedded with





copies of DNA from one particular gene






copies of DNA from several different genes with similar functions






copies of DNA from several different genes with different functions






copies of mRNA from one or more genes


4 points


Question 8


"When we say that the cDNA derived from our sample has hybridized to a particular spot on the array, we mean that: "





The cDNA from the sample has stuck to the DNA on the microarray at that point.






The cDNA from the sample is jumbled and cannot be trusted.






The cDNA has been used to make an mRNA copy






You need to buy microarrays from different manufacturers and triangulate the results


4 points


Question 9


"In this particular experiment, we used red-labeled DNA to process the sample from _____________ tissue and the green-labeled DNA to process the sample from ___________. "





cancerous; normal






normal; cancerous






normal; normal






cancerous; cancerous


3 points


Question 10


"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "





genes expressed by both normal or cancerous skin cells.






genes that were not expressed at all in either normal or cancerous skin cells






"genes expressed by cancerous, but not normal skin cells"






"genes expressed by normal, but not cancer skin cells. "


4 points


Question 11


"In interpreting the results of this study, spots on the microarray that are red correspond to:"





genes that are turned up by cancer






genes that are turned down by cancer






genes that are unaffected by cancer






genes that aren t expressed in normal or cancerous cells


4 points


Question 12


"In interpreting the results of this study, spots on the the microarray that are green correspond to genes that are "





genes that are turned down by cancer






genes that are turned up by cancer






genes that are unaffected by cancer






genes that aren t expressed in normal or cancerous cells


3 points


Question 13


"When the DNA microarray study tells us that a large number of genes have been turned up (or turned down) by a disorder, the most likely explanation is that "





the turned up genes are likely controlled by a gene that has gone bad






all of these genes are genes that have gone bad themselves






even just one mutation in any of these affected genes would have been sufficient to cause the disorder






the cytoplasm has too many free radicals in it


4 points


Question 14


A gene shown by the microarray to be expressed is :





"probably making protein, but a protein expression analysis would be needed to know for sure"






definitely making protein






definitely not making protein






probably making protein but there's no way to know for sure


4 points


Question 15


"In the application of this technique to skin cancer, a gene that has gone bad "





"may or may not be identified at all, but the overall pattern of results can give important clues"






can almost always be identified via DNA microarray
