DNA is made up of molecules callednucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
There are 4 types of RNA, each encoded by its own type of gene:
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.
snRNA - Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in eukaryotes. (Not found in prokaryotes.)
