The correct sequence of code transfer during polypeptide formation is DNA
→
mRNA
→
tRNA
→
amino acids. This is known as the Central Dogma of Molecular Biology. The information in DNA is carried by messenger RNA to the site where proteins can be made, which is the ribosome. The ribosome uses the information brought in by mRNA, according to which tRNA brings in the correct amino acid in the respective sequence, eventually forming the polypeptide.
