The correct answer is 3.15 ×10 ^ -7 m which is the length of the protein molecule.
According to the question the diameter of the hydrogen atom is, 1.05 * 10 ^ - 10 meters. A protein molecule is 3000 * 1.05 * 10 - 10 (or, 3 * 10 3 * 1.05 * 10 - 10) meters long.
=(3 * 1.05)^(10 - 10 * 10 3)
= (3.15 *^ 10 (- 10 + 3))
=3.15 *^ 10 -7meters
The protein molecule has a length of 3.15 * 10 - 7 meters.
A protein molecule is composed of a long chain of these amino acids, each of which is linked to its neighbor via a covalent peptide bond (Figure 3-1). Polypeptides are another name for proteins. Each protein has a distinct sequence of amino acids that is identical from one molecule to the next.
