E)DNA, genes, carbon dioxide, amino acids

Question

Quizplus · Accepted Answer

The correct order from largest to smallest is DNA (which is made up of genes), genes, amino acids, and carbon dioxide. DNA is larger than individual genes, which are made up of sequences of nucleotides. Amino acids are smaller than genes, as they are the building blocks of proteins, which are created from the sequence of amino acids coded for by genes. Carbon dioxide is the smallest molecule on the list. DNA is the largest molecule on this list, followed by genes which are smaller segments of DNA. Amino acids are the building blocks of proteins and are smaller than genes. Carbon dioxide is the smallest molecule on this list. Therefore, the correct order from largest to smallest is DNA, genes, amino acids, carbon dioxide.
