12 RNA Part 3 - mRNA, tRNA, rRNA And RNA-World Hypothesis

Join BioSpeak as we explore the roles of the three main RNA types—mRNA, tRNA, and rRNA—in cellular life. Discover how mRNA carries genetic instructions from DNA to ribosomes for protein creation, how tRNA transports amino acids in response to mRNA codons, and how rRNA stabilizes ribosomes, catalyzing peptide bond formation to link amino acids. This episode also introduces the RNA-World hypothesis, proposing RNA as the precursor of life due to its dual ability to store information and trigger biochemical reactions. Tune in to understand RNA’s central role in biology and its potential origins in early evolution.
