Summary Introduction
To review:
The common structural features that all tRNA molecules have.
Introduction:
The tRNA (transfer ribonucleic acid) helps in decoding of messenger RNA, which lead in protein synthesis. The molecule of tRNA was discovered by Paul. C Zamecnik. It is also known as an adaptor molecule.
