We have developed a method for introducing mutations into the adenovirus type 2 genome at predetermined sites. Specific mutations are introduced into segments of the viral genome cloned in bacteria by using plasmid vectors. The chimeric DNA is used to construct viral mutants by cotransfection with two viral DNA segments derived from both ends of the viral genome, each of which has overlapping s...

VA RNA(I) is a non-coding adenoviral transcript that counteracts the host cell anti-viral defenses such as immune responses mediated via PKR. We investigated potential alternate secondary structure conformations within the PKR-binding domain of VA RNA(I) using site-directed mutagenesis, RNA UV-melting analysis and enzymatic RNA secondary structure probing. The latter data clearly indicated that...
