Career.
In 1957 together with Andrey Nikolayevich Belozersky (Андрей Николаевич Белозерский) he conducted comparative analysis of bacterial DNA and RNA, and predicted existence of messenger RNA. He gave the first qualitative description of the structure of high-polymer RNA (1959–61). In 1963 he discovered structural transitions of ribosomes and formulated one of the principles of structure of ribosomes. He discovered artificial ribosomal self-assembly (1963–66) and proposed a molecular mechanism of the ribosome role in protein synthesis (1968). He conducted extra-cellular protein synthesis on modified ribosomes — non-enzymatic translation (together with L.P. Gavrilova) (1970–74).
In 1957, he defended his Candidate's Dissertation.
In 1962, he defended his doctoral dissertation.
