Living organisms are made up of several organic macromolecules known as biological polymers. For these macromolecules, mark the true statement. * 1 point DNA and RNA molecules are formed by the same nitrogenous bases. Nucleic acids are polymers of monosaccharides with structural functions. Starch and cellulose are proteins used by our bodies as a source of energy. Lipids are compounds formed by fatty acids, which can play important roles as digestive enzymes. Proteins are polymers of amino acids joined by peptide bonds and that can play mainly enzymatic and structural functions.

Hold on to his or her beliefs even if there is no evidence for those beliefs.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
