Remission is the disappearance or reduction of disease activity.

Resistance gene

A resistance gene contains the information for the production of a protein that makes an antibiotic ineffective and hence confers resistance against an antibiotic to a pathogen.


Retroviruses possess a genome made of ribonucleic acid (RNA), which they transcribe into DNA using an own enzyme. DNA is then integrated into the host cell’s genome.


Rhinoviruses are frequent causes of colds.


Rifampicin is an antibiotic especially used to treat mycobacterial infections.

RNA interference

RNA interference is a natural mechanism by which genes in cells can be targeted for silencing.

RNA viruses

RNA viruses are viruses whose genetic material is ribonucleic acid. Ribonucleic acid is a macromolecule that plays a decisive role in the conversion of genetic information into proteins.
