Las pruebas de PCR (reacción en cadena de la polimerasa) son una forma rápida y muy precisa de diagnosticar ciertas enfermedades infecciosas y cambios genéticos. Las pruebas detectan el ADN o el ARN de un patógeno (el organismo que causa una enfermedad) o células anormales en una muestra.
6 de mar. de 2023 · The polymerase chain reaction is a nucleic acid amplification testing procedure that consists of denaturing, renaturing, elongating, and amplifying a short segment of DNA or RNA. This is implemented by incorporating DNA I polymerase, which is derived from Thermus aquaticus, also known as Taq polymerase.
La reacción en cadena de la polimerasa, o PCR, es una técnica para hacer muchas copias de una determinada región de ADN in vitro (en un tubo de ensayo en lugar de un organismo). La PCR depende de una ADN polimerasa termoestable, la Taq polimerasa, y requiere de cebadores de ADN diseñados específicamente para la región de ADN de interés.
24 de ago. de 2021 · The polymerase chain reaction (PCR) test for COVID-19 is a molecular test that analyzes your upper respiratory specimen, looking for genetic material (ribonucleic acid or RNA) of SARS-CoV-2, the virus that causes COVID-19. Scientists use the PCR technology to amplify small amounts of RNA from specimens into deoxyribonucleic acid (DNA), which is ...
28 de feb. de 2022 · A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or...
PCR (polymerase chain reaction) tests are a fast, highly accurate way to diagnose certain infectious diseases and genetic changes. The tests work by finding the DNA or RNA of a pathogen (disease-causing organism) or abnormal cells in a sample.
17 de ago. de 2020 · Sometimes called "molecular photocopying," the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA.
