chemical digestion
Large food molecules are first broken down into smaller molecules through hydrolysis reactions. Enzymes facilitate this process by catalyzing the breakdown of bonds within the large molecules. The resulting smaller molecules can then be absorbed and utilized by the body for energy or building processes.
RNA contains nucleotides, which are the building blocks of RNA molecules. Nucleotides are connected in a specific sequence to form the RNA molecule.
DNA determines the sequence of the amino acids (building blocks) in a protein. The sequence of nitrogen bases in the DNA determines the sequence of amino acids in a protein.

Transcription.
The correct sequence of increasing organization from smallest to largest is: atoms, molecules, cells, tissues, organs, organ systems, and organisms. This hierarchy illustrates how matter is organized in biological systems, starting from the basic building blocks and culminating in complex living entities.

RNA molecules are produced by copying part of the nucleus sequence of DNA into a complementary sequence in RNA.
Protein molecules are made up of amino acid units, which are linked together in a specific sequence to form a polypeptide chain. The unique sequence of amino acids in a protein determines its structure and function.
Proteins are polymers of amino acids. The instructions for protein synthesis are contained within the genes (on DNA). This instructions are read from an mRNA at the ribosomes to produce the correct sequence of amino acids - a protein.
