Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some
The Array of Today
Jorge Cortese | Sep 3, 2000 | 10 min read
Human Arrays Human Arrays (continued) A 20th century scientist may have spent an entire career studying the function of a single protein, never imagining that one day it would be possible to study every human gene at once. This capability comes in the form of a microarray, a surface collection of immobilized genes that can be simultaneously examined with specialized equipment.1 Many current applications of arrays, also known as biochips, can be used in functional genomics as scientists seek ch
