WebMay 6, 2024 · RNA is a single-stranded molecule that can complement or "match up" to DNA. A type of RNA called messenger RNA or mRNA reads DNA and makes a copy of it, through a process called transcription. mRNA carries this copy from the nucleus to ribosomes in the cytoplasm, where transfer RNA or tRNA helps to match amino acids to …
