Bernard Moss, Aaron Shatkin and colleagues show that messenger RNA contains
a specific nucleotide cap at its 5' end which affects correct processing during
translation.
These discoveries in reovirus
and vaccinia virus were subsequently
found to apply to cellular mRNAs - a fundamental principle of eukaryotic cell
biology. See how useful viruses are?

Georges Köhler and César Milstein isolate the first monoclonal antibodies from clones of cells selected in vitro to produce an antibody of a single specificity directed against a particular antigenic target. This makes it possible to look not only at whole virus particles, but at specific regions - epitopes - of individual virus antigens (Nobel prize, 1984). |
