Transfer RNA
Transfer RNA is an adaptor molecule composed of RNA, typically 73 to 93 nucleotides in length, that is used in biology to bridge the three-letter genetic code in messenger RNA with the twenty-letter code of amino acids in proteins. The role of tRNA as an adaptor is best understood by...

 (tRNA). Through his later work, he is credited as the inventor of antisense therapeutics. Throughout his career, Zamecnik earned over a dozen US patents for his therapeutic techniques. Up until his death in 2009 he maintained a lab at MGH where he studied the application of synthetic oligonucleotides (antisense hybrids) for chemotherapeutic treatment of drug resistant and XDR tuberculosis in his later years.

After retiring from Harvard Medical School he continued his research at the Worcester Foundation for Biomedical Research with his former colleague Dr. Hoagland. When the foundation merged with the University of Massachusetts Medical School in 1997, Dr. Zamecnik moved his laboratory to MGH, where he continued to work until several weeks before his death.
