Genomic re-assessment of the transposable element landscape of the potato genome
(Springer, 2020-05)Transposable elements (TEs) are DNA sequences with the ability to autoreplicate and move throughout the host genome. TEs are major drivers in stress response and genome evolution. Given their significance, the development ... -
Genotipificación de variantes de beta-caseína bovina mediante ACRSPCR- RFLP = Genotyping of bovine beta-casein variants by ACRS-PCR-RFLP
(Consejo de Rectores de Universidades Privadas, 2023-10)Las variantes de la beta-caseína bovina pueden clasificarse en dos grupos, tipo-A1 y tipo-A2, según el aminoácido que esté presente en la posición 67 de la proteína (His, tipo A1; Pro, tipo A2)1. En los últimos años se ha ... -
Genotoxic effects induced by Cd+2, Cr+6, Cu+2 in the Gill and Liver of Odontesthes bonariensis (Piscies, Atherinopsidae)
(2016)Genotoxic effects of Cd?2, Cr?6, and Cu?2 on the gill and liver of the Argentinean Silverside (Odontesthes bonariensis) were studied using the comet assay and in relation with the metal tissue accumulation. Fish were exposed ... -
