Summary
This document describes the structure and properties of various RNA types including messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). It explains the roles of these different RNA types in cellular processes, specifically protein synthesis. Understanding these structures and functions is crucial in molecular biology.

Ribosomal RNAs (rRNAs) and transfer RNAs (tRNAs) exhibit substantial secondary structure, as do some messenger RNAs (mRNAs). ❑ Messenger RNA (mRNA) mRNA- single strand that carries messages from the DNA in the nucleus to the ribosomes in the cytosol ❑ Ribosomal RNA (rRNA) is a single strand in globular form, rRNA binds with proteins to make up ribosomes ,these all come together and form a complex that can read messenger RNAs and translate the information they carry into proteins. ❑ Transfer RNA (tRNA) tRNA- is a cloverleaf shaped single strand that carries amino acids to the ribosome and helps to assemble them in the correct order
