CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe temperature dependence of the T4 DNA ligase-catalyzed joining of plasmid DNA linearized by the action of HaeIII, EcoRI and PstI restriction endonucleases has been investigated by electron microscopy analysis. The extent of joining is maxi mal at 40 and decreases with increasing temperatures following sigmoid - like curves. The temperature at which 50% of the maximal reaction is still observable increases going from DNA termini without single-stranded overlaps (produced by HaeIII) to termini with four nucleotides overlap, composed only by two A and two T (produced by EcoRI) to termini with four nucleotide overlap, composed by A, T, G and C (produced by PstI).
