Protein synthesis
Protein synthesis is the creation of proteins via translation on a ribosome, involving mRNA, tRNA and rRNA.
mRNA
mRNA is a copy made of the DNA by RNA polymerase II and spliced to take out all the introns. This is a single polynucleotide strand that have codons made up of Adenine, Guanine, Cytosine and Uracil and instead of a deoxyribose in the sugar phospate backbone there is a ribose molecule.
