Rich is perhaps best known for the elucidation of the three-dimensional structure of a transfer RNA molecule, and for the discovery of an alternative form of DNA that exists in certain biological contexts, known as Z-DNA. Rich worked as a section chief in physical chemistry at the National Institutes of Health from to As a young man, Rich was smart, resourceful, and ambitious and he received a fellowship to Harvard College and later attended Harvard Medical School. Hoping to see some amount of base pairing, Rich mixed the two preparations together and was amazed to see the entire contents become converted into RNA with the properties of double-stranded molecules. Personal life[ edit ] Rich spent his early life in Springfield, Massachusetts. The rate of hybridization is limited only by the rate of diffusion of molecules in solution. Although its direct involvement had not yet been shown, RNA was strongly suspected to have a central role in this process. His age is around 30 years old.

As a young man, Rich was smart, resourceful, and ambitious and he received a fellowship to Harvard College and later attended Harvard Medical School. This may be the first articulation of the now widely accepted idea of an RNA world. Such spontaneous base pairing between different nucleic acid chains is known as hybridization and is the fundamental underlying chemical process by which the information in DNA is translated into protein.

Rich is perhaps best known for the elucidation of the three-dimensional structure of a transfer RNA molecule, and for the discovery of an alternative form of DNA that exists in certain biological contexts, known as Z-DNA. Rich worked as a section chief in physical chemistry at the National Institutes of Health from to The base-pairing rules — adenine pairs with thymine and guanine pairs with cytosine — are imposed by the geometric constraints on the paired bases as they are held together by hydrogen bonds in the central core of the helix. Hybridization is the process by which single-stranded RNA or DNA molecules can find each other in solution by the exact matching of complementary base sequences.

This molecule provided a structural basis for copying information from the gene sequence in DNA into a complementary single-stranded messenger RNA molecule. Because of its remarkable speed and specificity, hybridization remains today as one of two fundamental methods for reading out the identity of RNA or DNA molecules in different contexts — the direct determination of the base sequence, with the other being carrying out the matching by computer. This may be the first articulation of the now widely accepted idea of an RNA world.

Also, he looks tall, handsome and muscular. In one reaction, they prepared a long strand of RNA with only adinines oligo-A and in a separate reaction a long strand of RNA made up entirely of uracil oligo-U. Rich took a job at the NIH.

Rich was captivated by the connection, as so beautifully illustrated by the DNA model, between chemical structure and biological function and he was determined to make his mark in this new field as a structural biologist.
