7*) Knowing that there are 20 different possible amino acids that can be used at each position in a polypeptide, calculate the number of different polypeptides that could theoretically be produced for a protein that is 180 amino acids in length. Do you expect to find all these possible protein sequences produced in nature? Please explain your answer.
Neutral Amino Acids
Amino acids which do not have any charge on them are neutral amino acids.
Globular Protein
The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than other types which might not exhibit solubility. Many classes of the fold are found in globular proteins, which render them a sphere shape. Globular fold containing proteins usually are referred to by the term globin.
Dimer
Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodimer, the non-identical dimers are called heterodimer. The method by which dimers are formed is known as “dimerization”.
Dipeptide
A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.

8*) Determine whether the following statements are true or false, and explain your answer in one sentence.
a) The rate law for an overall reaction 2A (g) → B (g) is: Rate = k[A]^2
b) The rate law for an elementary step 2A (g) → B (g) is: Rate = k[A]^2
c) The rate of an overall reaction is the rate of the slowest elementary step within its mechanism.
