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.”

Merging two concepts: finding genes that are both essential and core

Bacterial Genetics and Genomics book Discussion Topic: Chapter 3, question 13 One of the concepts that is discussed in Bacterial Genetics and Genomics is the difference between essential genes and accessory genes. The essential genes are those that are required for the bacteria to live and the accessory genes allow it to do something elseContinue reading “Merging two concepts: finding genes that are both essential and core”

What can we learn from bacterial genome sequences that are never ‘finished’ and are left in pieces?

Bacterial Genetics and Genomics book Discussion Topic: Chapter 17, question 14 When we first started sequencing bacterial genomes, back in the 1990s, the goal was to ‘finish’, to generate a complete, closed, circularized chromosomal sequence that as accurately as possible reflected what would be seen in the bacterial cell. This process often took months, ifContinue reading “What can we learn from bacterial genome sequences that are never ‘finished’ and are left in pieces?”
