There are 20 common amino acids (pre-modification). In a set of any four, each one could be one of 20, meaning there are 204 possible combinations: 160,000.
If the question was meant to be "how many amino acids can be made from 4 triplet codons then the answer would still be exactly the same. Even though there are 4 bases, meaning there are 64 different codes possible, there are still only 20 amino acids available.
If the question was meant to be "how many amino acids can be made from 4 bases" you can only make one (which could be any of 20 different residues), as you need three bases to code one amino acid.
See the related question below for a listing of the types of amino acids.

How many nitrogen bases signal for four amino acids?
Four amino acids are coded by a sequence of 12 nitrogen bases. This is because each amino acid is represented by a codon, which consists of three nitrogen bases. Therefore, to represent four amino acids, you need 4 codons, leading to a total of 4 x 3 = 12 nitrogen bases.
How are codons used in polypeptide formation?
Four 'types' of nucleotide bases - when they are read three-at-a-time - this is considered to be a triplet-codon. Triplet codons are individually related to one specific amino acid, a polypeptide being a short protein.
How many codons are needed to specify 2 amino acids?
each codon have 3 nitrogenous bases . 3 nitrogenous bases = 1 amino acid or say 1 codon =1 amino acid ,so 2 codon = 2 amino acid
Why are there 20 amino acids in a protein?
There are 64 DNA codons (possible sequences of the 3-letter nucleotide bases A - adenine, T - thymine, which is replaced by U - uracil in RNA, C - cytosine and G - guanine) but only 20 possible amino acids because of the possibility of mutations that would replace one nucleotide base with another. For example, both AAA and AAG code for the production of lysine. This means that if a codon sequence was originally AAA and a mutation or an error in copying the DNA strand placed guanine in place of the final adenine, lysine would still be coded for. Though there are many possible errors that would cause an incorrect amino acid to be produced - for example, if cytosine was in place of the final adenine, asparagine would be coded for - having more than one codon per amino acid reduces the chances of a wrong amino acid being produced.
Is thymine an amino acid?
No, it is NOT, although it is often claimed to be. It is a sulfonic acid, but NOT an amino acid. Why not, you may ask? This is due to the scientific definition of how an amino acid has to be composed: Amino acids are defined as organic acids with an amino group (-NH2) and a carboxy group (-COOH) attached to a chain of carbon atoms of varying length. A look a the structural formula of taurine shows that this is clearly not the case: The hydroxy group (-OH) as well as the doubly bonded oxygen are attached to a sulfur atom and not to a carbon atom.
When the four DNA bases are combined in triplets different what of the protein are called for?
When the four DNA bases are combined in triplets, different amino acids are called for. Each triplet of bases, called a codon, corresponds to a specific amino acid, which is part of the protein synthesis process.

How many molecules of water are formed when four amino acids join?
Three water molecules are formed when four amino acids join together through a process called condensation or dehydration synthesis. Each amino acid has a carboxyl group (-COOH) and an amino group (-NH2), and when they combine, a water molecule is removed for each bond formed between the amino group of one amino acid and the carboxyl group of another.
How many nitrogen bases signal for four amino acids?
Four amino acids are coded by a sequence of 12 nitrogen bases. This is because each amino acid is represented by a codon, which consists of three nitrogen bases. Therefore, to represent four amino acids, you need 4 codons, leading to a total of 4 x 3 = 12 nitrogen bases.
How many symbols are in the genetic code?
there are 64 codon for diffrent amino acids in human being and three amino acid codon for a specific amino acid eg AUG stand for methionin amino acids ADENINE URACIL GUANIN
How are codons used in polypeptide formation?
Four 'types' of nucleotide bases - when they are read three-at-a-time - this is considered to be a triplet-codon. Triplet codons are individually related to one specific amino acid, a polypeptide being a short protein.
How does changing the sequence of nitrogen bases affect the protein that is produced?
You have four nitrogenous bases. They are adenine, guanine, cytosine and thiamine. They can denote only four amino acids. In next step you can put the same four bases. Now you get 4 * 4 = 16 base sequences. You need total 22 such sequences to denote twenty amino acids and two for start and stop gene. So nature has to take the third base pair added to the sequence. Now that you have 4 * 4 * 4 = 64 sequences. They are enough to denote the 22 sequences that you need. So three such base sequences is called as codon. Now you have 64 such codons. Some of them may denote the same amino acid. Now by changing the base pair may lead to denoting the different amino acid. That will lead to changing the sequence of amino acid in protein molecule. By changing the single amino acid in the protein, you get different type of protein. It can lead to formation of antibody against that particular protein.
How many distinct dipeptides can be made from the four amino acids leucine histidine alanine and valine?
There are a total of 16 possible dipeptides that can be formed from combining the four amino acids (4 amino acids * 4 amino acids = 16 dipeptides).
What are the four amino acids called?
There are actually 20 different amino acids, each one distinct in an R-group side chain. Did you mean what are the four parts of amino acids called? Because if so, they would be an amine (N) terminus (The NH2), carboxyl (C) terminus (The COOH), an H group of just a hydrogen atom, and an R group which is unique for each amino acid and identifies it from other amino acids. These four groups are bound to a central carbon atom. H O H\ / // N--C---C H/ \ \ R OH
How many codons are needed to specify 2 amino acids?
each codon have 3 nitrogenous bases . 3 nitrogenous bases = 1 amino acid or say 1 codon =1 amino acid ,so 2 codon = 2 amino acid
Excluding the stop sequence how many nucleotides are necessary to code for a polypeptide that is 100 amino acids long?
300 nucleotides are needed to code for a polypeptide that is 100 amino acids long, because each amino acid is coded for by a sequence of 3 nucleotides (codon), and there are 100 amino acids in the polypeptide.
