Nucleotide sequences of similar size from the coliphage R17 genome
Abstract
A sequence of 33 nucleotides from the coliphage R17 RNA genome was determined. It constitutes the main component of a mixture of fragments that migrate together on electrophoresis in a separation according to molecular weight. Fragments of comparable chain length from 3' end of RNA from coliphage R17, from a region preceding and overlapping the coat-protein cistron ribosome binding site and from the beginning of the A-protein cistron, were also found and characterized. ;Hairpin'-like secondary structures are proposed for the longer fragments, one of which appears to have a tetranucleotide excised in the loop region.
