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.
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.
