mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.
Antibodies in vivo. Antibody-based therapies have recently been studied. They ar\ne often the focus of attention in chemistry topics. It is a topic that should be developed very much. They are not generated by AI.
