DNA and RNA: Structure and Essential Biological Functions

This video features an educational song that clearly and engagingly explains the structure and function of DNA and RNA, the central molecules responsible for storing, transmitting, and expressing genetic information.

The music introduces DNA as a double-helix molecule composed of nucleotides that include a sugar, a phosphate group, and nitrogenous bases. It highlights the specific base pairing — A with T and C with G — which ensures the stability of the genetic code and enables processes such as replication, essential for cell division and the continuity of life.

RNA is described as a single-stranded molecule whose main function is to participate in protein synthesis, translating DNA instructions into functional molecules. The song emphasizes the three major types of RNA:
• mRNA (messenger RNA) — carries genetic information to the ribosomes;
• tRNA (transfer RNA) — delivers the correct amino acids for protein assembly;
• rRNA (ribosomal RNA) — forms the structural and catalytic core of ribosomes.

The lyrics also explain transcription (when DNA is converted into RNA) and translation (when RNA directs protein formation), demonstrating how these sequential processes sustain cellular activity.

With rhythmic, clear, and memorable verses, the video makes molecular biology accessible and enjoyable, offering an ideal learning tool for students who want to understand the fundamental mechanisms behind the code of life.
