DNA microarray technology allows a researcher to analyze gene expression in an organism cultured under different growth conditions. True/False
Homework Answers
The answer should be TRUE.
As profiles of gene expression of both of the growth conditions can be seen together or seperately by microarray and then can be compared with each other.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Tissue-specific microarray analysis facilitates the comparison
of gene expression in different tissues. In order to prepare a
sample for microarray analysis, messenger RNA (mRNA) is extracted
from a particular tissue, reverse transcribed to generate
complementary DNA (cDNA), and labeled with a fluorescent probe.
The microarray below shows comparison of gene expression in
stomach and intestinal tissues. The cDNA from stomach tissue was
labeled with red fluorescent probes, whereas the cDNA from the
intestinal tissue was labeled with green fluorescent probes....

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?

Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...

3. This is a schematic of a very simple pattern of gene expression. Yes means the protein is present and can bind the promoter. No means the protein is absent. Transcription factors are proteins that help regulate transcription by binding DNA Activators are transcription factors that help transcription. For example, they bend the promoter and make it accessible to RNA polymerase. Repressors are transcription factors that inhibit transcription. For example, they might bind the promoter and stop the RNA polymerase...

Which of the following statements regarding gene mutations is NOT true? Conditional mutations have different phenotypic effects under different conditions and can be used to study the function of essential genes. Silent mutations cannot have any phenotypic effect on an organism. Frameshift mutations often result in a truncated protein product, similar to a nonsense mutation. Dominant mutations have a phenotypic effect despite the presence of one functional wild type allele.
