Question

A single-stranded DNA sequence is attached to a microarray chip, and fluorescently labeled complementary RNA (cRNA) fragments (probes) prepared from mRNA isolated from a cell sample are incubated with the array chip under hybridizing conditions. Data specifically regarding the _________ are measured by this type of microarray.

Choose one:
A. genome B. transcriptome C. glycome D. proteome

Answer 1

Option A , Genome

Step-by-step explanation:

Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.

Hence, option A is correct
