Question

Under which of the following circumstances would a DNA microarray be useful? Multiple Choice It would enable a researcher to determine the differences in gene expression between cell types. Researchers are trying to determine if an individual has inherited a genetic disease from their parents. It would enable doctors to determine which genes are responsible for producing diseased tissue in an individual. All of these are circumstances in which a DNA microarray would be useful. None of these are circumstances in which a DNA microarray would be useful.

Answer 1

Answer:

The correct answer is ''All of these are circumstances in which a DNA microarray would be useful.''

Explanation:

A DNA microarray is used to determine the complete genetic expression of a tissue at a given time. DNA microarrays is one of the most important applications for the information obtained from the systematic sequencing of complete genomes. They consist of a membrane, which can be made of nylon, silicone or a simple glass slide. The DNA of many genes, arranged according to a specific pattern, is immobilized on this membrane. These DNA fragments, which are known as probes or oligos, are arranged in microscopic spots. Microarray technologies are used in research at the molecular level, they allow the study of simple changes in the DNA sequence and mutations in complex genes that are associated with a specific disease, helping to diagnose diseases.
