There are two types of endoplasm reticulum(ER), they are rough ER and smooth ER. If a strand of mRNA is lucky enough to go through rough ER (called that because of the ribosomes on the walls of the canal) it can start, and complete the process of translation immediately. If an unlucky strand of mRNA goes through smooth ER, it passes into the cytoplasm. There, tRNA combines with the single strand of mRNA on a free-floating ribosome to form polypeptides (and to complete the process of translation). But how? Amino acids have a trio of tRNA on them. tRNA is just three nitrogenous bases. When mRNA is on the ribosome, it is understood that the nitrogenous bases are set into groups of three. These are called codons. Codons are already pre-determined by a triplet that was formed by the original DNA. This is called a DNA triplet. The amino acid and tRNA, which are already attached to it, are called an anti-codon, because they combine with the
