Miracles of Science #3: RNA World Part 2

In Part 2 of the n-Lorem Patient Empowerment Program podcast Miracles of Science series on RNA, Dr. Stan Crooke further explores the fascinating “RNA world,” explaining how RNA molecules are processed, protected, modified, and used to manage cellular function. The episode breaks down concepts like pre-RNAs, poly-A tails, 5’ caps, RNA splicing, and the multiple “codes” that make RNA dynamic and information-rich — foundational science that helps power antisense therapies for nano-rare patients and helps make the RNA world a true "Miracle of Science," allowing n-Lorem to fulfil its mission.

Shownotes:

0:00 — Introduction to n-Lorem Overview of the n-Lorem Foundation mission and support for nano-rare patients and families.

0:15 — Podcast & Sponsor Introduction Dr. Stan Crooke introduces the podcast and acknowledges sponsor ChemGenes.

1:17 — Entering the “RNA World” Dr. Crooke introduces RNA biology and explains why RNA science is foundational to antisense therapies.

1:31 — What Are Pre-RNAs? Explanation of immature “pre-RNAs” and how they contain instructions for cellular processing and transport.

3:31 — RNA Processing & Adding Nucleotides Discussion of how RNAs are trimmed and modified during maturation.

4:03 — Poly-A Tails Explained What poly-A tails are, why they are added to messenger RNA, and how they protect RNA molecules.
