This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
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.
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.
Phylogeny of Orthornavirae RNA-dependent polymerase. The five colored branches are the five phyla of Orthornavirae.. Both kingdoms in Riboviria show a relation to the reverse transcriptases of group II introns that encode RTs and retrotransposons, which are self-replicating DNA sequences, the latter of which self-replicate via reverse transcription and integrate themselves into other parts of ...
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]
It is the first step of viral replication. Some viruses attach to the cell membrane of the host cell and inject its DNA or RNA into the host to initiate infection. Attachment to a host cell is often achieved by a virus attachment protein that extends from the protein shell (), of a virus.
The virus then releases its genetic material (either single- or double-stranded RNA or DNA) into the cell. In some viruses this genetic material is circular and mimics a bacterial plasmid . At this stage the cell becomes infected and can also be targeted by the immune system.
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]
