In all organisms, most of the traits are determined by proteins, synthesized by specific gene sequences, such as eye color, height, or hair color. Thus, the correct word to complete first statement is 'proteins.'

DNA is genetic material of all living organisms and viruses (except RNA viruses) that store genetic information. It is known as blueprint for proteins as it has instructions required for the protein synthesis. Thus, the correct word to complete second statement is 'DNA.'
