RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. A strand of RNA can be thought of as a chain with a nucleotide at each chain link. RNA can also be called a helix. RNA is also single stranded. There is three types of RNA...
- mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.
- tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
- rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
