It highlights their role in RNA processing, particularly in tRNA, rRNA, and mRNA, often through self-splicing. Key examples include ribonuclease P and Group I and II introns. Additionally, it touches on spliceosomes and viroids, noting that viroids can infect plants and exhibit self-splicing capabilities similar to ribozymes.

It consists of a phospholipid bilayer with hydrophobic tails inward and includes integral and peripheral membrane proteins. Integral proteins traverse the bilayer, while peripheral proteins are loosely attached. Some proteins are fixed in place by the cytoskeleton or extracellular matrix, and others are restricted by tight junctions.
