Question

Quizplus · Accepted Answer

Ribosomal RNA (rRNA) is commonly used in nucleic acid hybridization assays for identification of mycobacteria. This is because rRNA is highly conserved and contains both variable and conserved regions that can be targeted for identification. Additionally, rRNA is present in high quantities in bacterial cells, making it a reliable target for detection. DNA, transfer RNA, and messenger RNA are also present in mycobacteria, but rRNA is the most commonly used target for identification.
