Hace 3 días · PCR, o la reacción en cadena de la polimerasa, es una reacción química que los biólogos moleculares utilizan para amplificar (crear copias) fragmentos de ADN. Esta reacción permite que unos pocos fragmentos de ADN se repliquen en millones o miles de millones de copias.
Hace 2 días · Polymerase chain reaction (abbreviated PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied in greater detail.
Hace 4 días · La crisis pandémica ha acercado al dominio público términos y conceptos hasta ahora exclusivos del ámbito científico-técnico. Uno de ellos es la PCR, iniciales de polymerase chain reaction («reacción en cadena de la polimerasa»).Pero la PCR es mucho más que una técnica diagnóstica aplicada a muestras tomadas mediante el incómodo exudado nasofaríngeo para detectar el maldito SARS ...
Hace 2 días · In this video, we will introduce the basics of the Polymerase Chain Reaction, or PCR. We’ll review the history of PCR, typical components and principles of the reaction, polymerases available, PCR reaction types, and the various applications of this widely used molecular biology technique.
Hace 3 días · Reverse transcription polymerase chain reaction (RT-PCR) first uses reverse transcription to obtain DNA, followed by PCR to amplify that DNA, creating enough to be analyzed. RT-PCR can thereby detect SARS-CoV-2, which contains only RNA. The RT-PCR process generally requires a few hours.
Hace 5 días · To prepare such a long DNA duplex incorporating the guest-modified adenosines, we considered employing a polymerase chain reaction (PCR)-mediated substitution system (Figure 6b). (17) This method, which utilizes a chemically modified primer, was expected to provide the amplified DNA sequence while substituting the designated position with the guest-modified adenosines.
Hace 5 días · The DNA amplification method has contributed to remarkable developments in biotechnology and molecular biology. The most basic and oldest method of DNA amplification, the polymerase chain reaction (PCR), has been used for various purposes, such as gene cloning, disease diagnosis, and bacterial or viral detection, in the fields of medicine, agriculture, environment, and food.
