Nearly the whole of my research career took place in the present ‘golden age’ for the study of DNA, genes and genomes. At the end of the 1960s scientists had indicated how useful it would be to be able to isolate individual genes in order to study their structure and function. That wish was fulfilled in the spin-offs from the invention in the early 1970s, of genetic modification (genetic engineering), a scientific milestone that marked the start of this golden age.

By the end of the 20thcentury experiments were being done, that thirty years earlier were not even dreamed of. This was certainly true in my research group’s work on the biochemistry and genetics of DNA replication, giving us the real privilege of uncovering some of the beautifully complex and intricate mechanisms used by cells in ‘managing’ and copying their genetic material.

I have been thinking a lot recently about an aspect of evolution that is rarely talked about, namely that it has involved and continues to involve cooperation or collaboration between Continue reading

Magic and Metamorphosis

Children love to watch caterpillars turn into butterflies, and scientists are no less fascinated by this process. I have mentioned biologist John Bryant’s contribution to the science and faith discussion on this blog a number of times. In this guest post, he writes about his sense of wonder at the processes he studies.

I have been fascinated by the natural world for as long as I can remember, and that fascination led to a career in biology. As a professional biologist my main focus has been the way DNA works as genes, and especially the processes by which DNA is replicated prior to cell division.

Regular readers of this blog will know of the excitement, awe and wonder I have Continue reading
