[Primary structure of a fragment of cDNA from phage fr]. / Pervichnaia struktura fragmenta kDNK faga fr.

The nucleotide sequence of a 1392 bp fragment of phage fr cDNA has been determined. The fragment contains 3'-terminal part of the A-protein gene, the complete coat protein gene, and beginning of the replicase gene. A comparison between the sequences of the corresponding genes and regulatory regions from the phage fr and MS2 genomes reveals 320 base changes.
