Research record from J Clin Med, 2026-06-10. PMID 42355677.
Glossary Term
A sequence of single-stranded RNA, that is 20-25 nucleotides in length, which is transcribed from DNA but is not translated into a protein. This nucleic acid may regulate the transcription or translation of other genes.
Artículo
Research record from Lancet Rheumatol, 2026-08-27. PMID 42660164.
Glossary Term
Amplification of several targets in a single reaction using multiple primer pairs, each distinguishable by fluorescent channel or melting profile. Multiplexing raises information per sample but makes channel allocation, dye compatibility, and competition between targets key selection criteria.
Glossary Term
Any transmissible change in the genetic material of an organism, which can result from radiation, viral infection, transposition, treatment with mutagenic chemicals and errors during DNA replication or meiosis. The effects of mutation range from single base changes to loss or gain of complete chromosomes. As many of the simpler alterations to DNA may be repaired, such changes are only heritable once the change is fixed in the DNA by the process of replication. Mutations may be associated with genetic diversity or with pathologies including cancer.

Research record from Mol Cell Pediatr, 2026-04-08. PMID 41949810.
Glossary Term
Laboratory procedure in which single stranded nucleic acids are allowed to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. By this means the degree of sequence identity can be assessed and specific sequences detected. (From Biology-online)
Glossary Term
A statistical method to test if observations are significant or due to chance. It proposes that no statistical significance exists in a set of given observations and attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
Glossary Term
A small-scale mutation in which a single nucleotide is exchanged for another. Mutagenic chemicals and mistakes in DNA replication may result in point mutations.
