Top 20 Quotes by Richard J. Roberts

The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily breaks these hydrogen bonds, allowing the two strands to separate - a process called denaturation or melting.

Much of my work in biology has been driven by my early training in chemistry. When studying a new chemical compound, the first and most important thing is to determine its detailed molecular structure.

I am a passionate reader, having been tutored very early by my mother. I avidly devoured all books on chemistry that I could find. Formal chemistry at school seemed boring by comparison, and my performance was routine. In contrast, I did spectacularly well in mathematics and sailed through classes and exams with ease.

My elementary education was at Christ Church infant school and St. Stephen's junior school. At St. Stephen's, I encountered my first real mentor, the headmaster Mr. Broakes. He must have spotted something unusual in me, for he spent lots of time encouraging my interest in mathematics.

During normal cell metabolism, RNA is constantly being made and broken down. The purine and pyrimidine residues are reused by several salvage pathways to make more genetic material. Purine is salvaged in the form of the corresponding nucleotide, whereas pyrimidine is salvaged as the nucleoside.

The way health care is funded in the U.S. is not sustainable. People are being kept alive who are probably better off dead. The cost of health care is too high, and you don't get much for it - it's twice as high in the U.S. as elsewhere, and it's because of the middlemen.

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

I have been intimately involved in the techniques of genetic modification as a scientist since GMOs were first conceived. In that time, hundreds of studies and tests have been done on GMO safety - and we've seen no scientific evidence that GMOs are inherently more dangerous than crops produced by traditional plant breeding.
