World’s largest catalogue of ocean DNA could boost drug discovery

Drug Discovery World

For example, enzymes sourced from bacteria living around hydrothermal vents have been used to support the polymerase chain reaction, the test used for Covid-19 detection. ” The ability to collect and analyse such a new wealth of ocean data comes from major developments in DNA sequencing technology and computational power. .

Rising Demand for DNA and Gene Cloning  Service Providers

Roots Analysis

DNA cloning refers to the process of generating multiple copies of a particular DNA segment. DNA and Gene Cloning involves the isolation of a DNA sequence of any species ( often a gene ) and its insertion into a vector to enable growth without any alteration in the original DNA sequence.

RNA holds the reins in bacteria: U-M researchers observe RNA controlling protein synthesis

Scienmag

Credit: Surajit Chatterjee To better understand how RNA in bacteria gives rise to protein–and along the way, target these processes in the design of new antibiotics–researchers are turning their attention to the unique way this process happens in bacteria.

Bacteriophages: the viruses that can actually be good for you

Pharmaceutical Technology

Bacteria naturally develop resistance to antibiotics over time, through genetic mutation, horizontal gene transfer between bacteria, or because of selective pressure. Virus versus bacteria. Phages are viruses of bacteria. Secondly, the relationships between phages and bacteria are very specific.
