Ribonucleic acid, a nucleic acid essential for protein synthesis and gene regulation in living cells. Unlike DNA, it is typically single-stranded and contains ribose sugar.
Acronym from 'ribonucleic acid', coined in the 1930s. 'Ribo-' refers to ribose sugar, 'nucleic' from Latin 'nucleus' (kernel), and 'acid' from its chemical properties.
RNA is like DNA's versatile cousin - it can store information, catalyze reactions, and regulate genes. Some scientists believe RNA came first in evolution, making it the grandfather of all life as we know it!
