Top 20 Quotes by Richard J. Roberts

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.

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.

Hard as it is to imagine, there's a move afoot in Congress to take away the public's free online access to tax-funded medical research findings. That would be bad for medical discovery, bad for patients looking for the latest research results, and another rip-off of the American taxpayer.

The battle over genetically modified crops is rife with business interests and political opportunism. When GMOs were first produced in laboratories around the world, they were rightly heralded as a tremendous leap forward in our ability to supplement nature by providing high-nutrient foods.

One always has to worry when capitalism has a role in health care. If you're just using health care to make money, you will treat the wrong diseases. Capitalism has its limits. There is a role for governments, and this is one where they should be involved.

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.

From age 16 on, I found school boring and failed A-level Physics at my first attempt. This was necessary for university entrance, and so I stayed an extra year to repeat it. This time, I did splendidly and was admitted to Sheffield University, my first choice because of their excellent Chemistry Department.

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.

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.
