How many different polypeptides of 50 amino acids in length can be made from the 20 common amino acids?

20^50

Explanation:

A protein or polypeptide is a long chain of different amino acids covantently linked together with a peptide bond.

If we have 20 differents amino acids, and you want to generate a protein or a short peptide of just 2 amino acids we can generate 20 * 20 = 400 different proteins having different amino acids combination. It can also be represented as 20^2 =400

So also generating a short peptide of 3 distinct amino from 20 amino acids monomers we get 20^3 = 8000 distinct proteins.

So 20^n proteins can be made from 20 different amino acids.

Therefore making a protein on 50 amino acids long from 20 different amino acids, we get 20^50 distinct proteins.

Answer is 20^50

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
