What is true of DNA arrays?
A)They are typically used to determine the expression levels of only a single gene in one experiment.
B)They are useful for determining the changes in levels of protein in a cell in response to environmental stimuli..
C)They are used to measure the levels of mRNA and protein at the same time.
D)They can be used to compare the expression of mRNA from all the genes in cells under two different environmental conditions

Question

Quizplus · Accepted Answer

DNA arrays can be used to compare the expression of mRNA from all the genes in cells under two or more different environmental conditions. This allows for the identification of genes that are differentially expressed, or upregulated/downregulated, in response to specific environmental factors. This information can be used to gain insights into the molecular mechanisms underlying environmental responses and cellular processes.
