Harnessing aptamers for rapid detection of bacteria and antibiotics in our food.

Bacterial Genetics and Genomics book Discussion Topic: Chapter 4, question 14 The specificity of antibody binding has been exploited for many years in a variety of technologies. Although perhaps less famous, aptamers also have high binding specificity for their targets and, being made of RNA or DNA rather than protein, are much smaller in size,Continue reading “Harnessing aptamers for rapid detection of bacteria and antibiotics in our food.”

Bacteria breaking the rules – again. This time, its coupled transcription – translation.

Bacterial Genetics and Genomics book Discussion Topic: Chapter 2, question 14 It has long been a defining difference that bacterial cells, like E. coli, have coupled transcription-translation and eukaryotic cells, like animals and plants, make their mRNA in the nucleus and their proteins in the cytoplasm. This is mostly the case. Mammals did break theContinue reading “Bacteria breaking the rules – again. This time, its coupled transcription – translation.”

Studying fascinating microbiomes, working in cooperation with communities, and illuminating study design.

Bacterial Genetics and Genomics book Discussion Topic: Chapter 1, question 14 I recently attended and was an invited speaker, on-line, at a conference that had a topic about short-and long-read sequencing technologies. The various talks and the panel discussion that I participated in looked at the advantages of both short-read sequencing and long-read sequencing forContinue reading “Studying fascinating microbiomes, working in cooperation with communities, and illuminating study design.”

Biology Week Topic: Genomics, Earthquakes, and Cholera

Bacterial Genetics and Genomics book Discussion Topic: Chapter 11, question 14 Although I had planned to continue to work through the Discussion Topics from Bacterial Genetics and Genomics that are all related to the investigations in bacterial genetics and genomics using bioinformatics tools can be conducted outside of the lab, October here in the UKContinue reading “Biology Week Topic: Genomics, Earthquakes, and Cholera”

Bacterial genomes, then and now

Bacterial Genetics and Genomics book Discussion Topic: Chapter 17, question 13 The publications of the first bacterial genome sequences were 25 years ago. The technology has come a long way since then, both in the lab and computationally. One of the first bacterial genome sequencing projects started was one undertaken to sequence the complete EscherichiaContinue reading “Bacterial genomes, then and now”
