Glossary Term
General term for a piece of DNA or RNA corresponding to a gene or sequence of interest, that has been labelled either radioactively or with some other detectable molecule, such as biotin, digoxygenin or fluorescein. As stretches of DNA or RNA with complementary sequences will hybridize, a probe will label viral plaques, bacterial colonies or bands on a gel that contain the gene of interest.

Research record from Langmuir, 2026-03-16. PMID 41839765.
Glossary Term
An RNA molecule that does not contain protein-coding sequence information and constitutes the majority of the cellular RNA (~80%). This nucleic acid associates with multiple proteins to form ribosomes, which are the organelles that drive mRNA-directed protein synthesis.
Pruebas

Pruebas
The determination of the amount of SARS-related coronavirus RNA (including but not limited to SARS-CoV, SARS-CoV-2, and/or other SARS-like Coronavirus) in a biological sample.
Pruebas
The determination of the amount of SARS-related and/or MERS Coronavirus RNA which includes but not limited to SARS-CoV, SARS-CoV-2, other SARS-like Coronavirus, and/or MERS-CoV in a biological sample.

Pruebas
The determination of the amount of severe acute respiratory syndrome coronavirus 2 in a sample.
Glossary Term
A point mutation occurring within the protein-coding region of a gene, and which codes for the same amino acid as expected.
Pruebas
The determination of the amount of small-colony variant Pseudomonas aeruginosa present in a sample.
Indicadores
Tumor-associated oncofetal glycoprotein 72 (TAG-72) is a high molecular weight (220-400 kD) complex expressed by a wide variety of human adenocarcinomas. This antigen is expressed by a majority of invasive ductal breast carcinomas, and most colon, pancreatic, gastric, esophageal, lung (non-small cell), ovarian and endometrial adenocarcinomas, and on normal secretory endometrium, but not on other normal tissues. It is not expressed by leukemias, lymphomas, sarcomas, mesotheliomas, melanomas or benign tumors. The monoclonal antibodies against TAG-72 have been widely employed for the immunohistochemical analysis of adenocarcinomas as well as for radioimmunoscintigraphy and radioimmunoguided surgery.
Glossary Term
A class of short adaptor RNAs that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. Each transfer RNA comprises a three-nucleotide sequence that is complementary to the triplet nucleotide coding sequence of an mRNA, conferring specificity to the amino acid being incorporated into the assembling protein.
