  2. Reverse transcription polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcription...

    Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). [1] It is primarily used to measure the amount of a specific RNA.

    en.wikipedia.org/wiki/NASBA_(molecular_biology)

    Nucleic acid amplification is a technique used to produce several copies of a specific segment of RNA/DNA. [3] Amplified RNA and DNA can be used for a variety of applications, such as genotyping, sequencing, and detection of bacteria or viruses. [4] There are two different types of amplification, non-isothermal and isothermal. [5]

  4. Reverse transcriptase - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcriptase

    A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes.

    The first called IgM is highly effective at neutralizing viruses but is only produced by the cells of the immune system for a few weeks. The second, called, IgG is produced indefinitely. Therefore, the presence of IgM in the blood of the host is used to test for acute infection, whereas IgG indicates an infection sometime in the past. [ 8 ]

  6. Polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Polymerase_chain_reaction

    A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.

  7. Gain-of-function research - Wikipedia

    en.wikipedia.org/wiki/Gain-of-function_research

    In virology, gain-of-function research is usually employed with the intention of better understanding current and future pandemics. [4] In vaccine development, gain-of-function research is conducted in the hope of gaining a head start on a virus and being able to develop a vaccine or therapeutic before it emerges. [4]

  8. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    Reverse transcribing viruses replicate their genomes by reverse transcribing DNA copies from their RNA; these DNA copies are then transcribed to new RNA. Retrotransposons also spread by copying DNA and RNA from one another, [ 66 ] and telomerase contains an RNA that is used as template for building the ends of eukaryotic chromosomes .

  9. Northern blot - Wikipedia

    en.wikipedia.org/wiki/Northern_blot

    The northern blot, or RNA blot, [1] is a technique used in molecular biology research to study gene expression by detection of RNA (or isolated mRNA) in a sample. [ 2 ] [ 3 ] With northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression rates during differentiation ...
