The composition of proteins of chemically evoked mutants of TMV RNA.

摘要: The amino acid composition of the protein 29 chemically evoked strains tobacco mosaic virus is reported as a basis for preliminary understanding specific mechanism information transfer from viral ribonucleic to coat protein. About half these mutants showed same wild type. Twelve them 1, 2 or 3 replacements and 16 17 replacements. In few instances exchanges have been located in sequential position. were observed recur frequently, thus 6 replacement one proline by leucine, two identical serine was replaced phenylalanine. showing almost composition. number total acids all studied with nature chemical mutagen did not noticeably affect changes qualitative quantitative terms. only definite correlation that certain major biological change always accompanied alterations.
