- Location: RNA is predominantly found in the cytoplasm, involved in protein synthesis, but also in the nucleus for synthesis and processing. - Size: RNA molecules vary in length, with typical sizes for mRNA, tRNA, and rRNA falling within the 100-5000 base range. - Structure: RNA is typically single-stranded, allowing for complex folding and interaction. - Stability: RNA is sensitive to alkaline hydrolysis due to the 2'-hydroxyl group of ribose, making it alkali labile.
