Classification
Nouns denoting substances.
Examples
- The ribosomes in the cytoplasm use the RNA transcript for protein synthesis, where they translate the genetic code into a sequence of amino acids.
- Scientists discovered that some viruses use RNA as their genetic material rather than DNA.
- The RNA molecule plays a crucial role in the translation of genetic information from DNA to proteins in the cell.
- Researchers have been studying the structure and function of RNA molecules to better understand their role in cellular processes.
- The RNA world hypothesis proposes that RNA was the first molecule to store and transmit genetic information in the early stages of life on Earth.
