C. is the correct answer - <span>The sequence of amino acids in the polypeptide chain
Amino acids are subunits of proteins, they are the monomer ( building blocks) of proteins also called polypeptides. Each protein has a unique set of amino acids chain that make them distinctive.</span>
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
Messenger RNA<span> (</span>mRNA) is the RNA that carries information from DNA to theribosome<span>, the sites of protein synthesis (translation) in the cell. The coding sequence of the </span>mRNA<span> determines the amino acid sequence in the protein that is produced.</span>
D, because they produce the food for the consumers, like grass.
