No they are not. For a codon, there are 4^3 = 64 codon combinations, but only 20 [common] amino acids. The 4 represents the 4 nitrogenous bases, and the ^3 represents the arrangement into a codon (3 bp).
An example of an amino acid that is specified by more than one amino acid is Alanine, which is specified by any of the following combinations: GUU, GUC, GUA, GUG.
Because most amino acids have more than one codon, the genetic code is called "degenerate".

What amino acids are coded for by the mRnas?
mRNAs code for the 20 standard amino acids found in proteins. Each group of three nucleotides on the mRNA (codon) corresponds to a specific amino acid, as determined by the genetic code.
If you have aaaacugag as your mRNA what amino acids will that code for?
The mRNA sequence aaaacugag would code for the amino acids lysine-leucine-arginine. Each set of three nucleotides (codon) in the mRNA corresponds to one specific amino acid in the genetic code.
Monomer of proteins?
The monomer of proteins are amino acids. Amino acids are organic compounds that contain an amino group (-NH2) and a carboxyl group (-COOH), along with a side chain group that gives each amino acid its unique properties. Proteins are made up of long chains of amino acids linked together by peptide bonds.
How may different dipeptides are possible from the combination of two amino acids?
There are 400 possible dipeptides formed from the combination of 20 common amino acids (20 x 20 = 400). This is because each dipeptide consists of two amino acids and each amino acid can be paired with any of the other 20 amino acids.
What chain is proteins in?
Proteins are first produced as polypeptide chains. This is known as the primary structure of the proteins. Polypeptide or protein chain comprised of amino acids connected each other with peptide bonds.
What amino acids are coded for by the mRnas?
mRNAs code for the 20 standard amino acids found in proteins. Each group of three nucleotides on the mRNA (codon) corresponds to a specific amino acid, as determined by the genetic code.
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
If you have aaaacugag as your mRNA what amino acids will that code for?
The mRNA sequence aaaacugag would code for the amino acids lysine-leucine-arginine. Each set of three nucleotides (codon) in the mRNA corresponds to one specific amino acid in the genetic code.
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.
How do nucleotides in the RNA molecule code for various amino acids How many nucleotides code for one amino acid?
Each nucleotide is made up of an organic base, a pentose sugar and a phosphate. Nucleotides can be arranged in various different orders and that order dictates which amino acid it codes for, three amino acids code for one nucleotide. Is this enough detail?
How many codons are in 150 amino acids?
There are 150 codons required to code for 150 amino acids in a protein. Each amino acid is coded for by a specific sequence of three nucleotides (a codon) in the mRNA molecule during protein synthesis.
How many codons would be needed if a bacterial protein contains 150 amino acids?
1. the start codon 2. 150 codons, 1 for each amino acid 3. the stop codon The total number of different codons is 64...if this question is asking about unique codons used the answer will depend on which amino acids are in the peptide.
To create amino acids the genetic code requires nucleotides?
Yes, amino acids are the building blocks of proteins and are created through the translation of the genetic code. This process involves the sequence of nucleotides in mRNA being read in groups of three (codons), each of which corresponds to a specific amino acid. This relationship between nucleotides and amino acids is crucial for protein synthesis.
In DNA every three bases is called?
In DNA, every three bases is called a codon. Each codon corresponds to a specific amino acid during protein synthesis.
How many amino acids would be in a protein that is coded by a DNA strand ninety-nine nucleotides long?
There would be 33 amino acids in the protein, as each amino acid is coded for by a sequence of three nucleotides called a codon. Thus, 99 nucleotides would code for 33 amino acids (99 divided by 3).
What does each codon code for?
Each codon codes for a specific amino acid, which is a building block of proteins. The sequence of codons in mRNA determines the sequence of amino acids in a protein. There are 64 possible codons, with 61 coding for amino acids and 3 serving as stop codons to signal the end of protein synthesis.
Why must bases be grouped in triplents in order to represent amino acids?
Bases are grouped in triplets to represent amino acids because each triplet of bases (called a codon) codes for a specific amino acid in the genetic code. There are a total of 64 possible codons (4 bases raised to the power of 3), which is more than enough to code for the 20 amino acids found in proteins. This triplet code allows for redundancy and accuracy in translating genetic information into proteins.
