Yes, each amino acid is encoded by three bases in the mRNA molecule, however not all bases in the mRNA encode for an amino acid. For example; UAG, UGA and UAA are termed stop codons which do not encode for an amino acid, but rather signal for translation to stop and cause the ribosome to dissociate from the mRNA. Also, all bases after the stop codon or before the start codon (AUG) will not code for amino acids.
No, multiple codons can code for the same amino acid due to redundancy in the genetic code. This redundancy is known as degeneracy and helps protect against mutations causing significant changes in the resulting protein.

The unique 3 base pair structure for an amino acid is called?
The unique 3 base pair structure for an amino acid is called a codon. Codons are specific sequences of three nucleotides in mRNA that correspond to a particular amino acid during protein synthesis.
Does every codon represent an amino acid?
No, not every codon represents an amino acid. There are several codons known as "stop" codons (UGA, UAA, UAG) that do not code for an amino acid; instead they code for the termination of translation.
Are amino acids only represented by one codon?
No, amino acids can be represented by multiple codons. This is due to the redundancy in the genetic code, where different codons can code for the same amino acid.
Why is it possible for an amino acid to be specified by more then one kind of codon?
There are 64 possible codons but only 20 amino acids, this means that some amino acids have multiple codons that can code for them. This redundancy in the genetic code helps to protect against errors during transcription and translation.
What codons specify the amino acid arginine?
AGG, AGA, CGA, CGC, CGU, and CGG specify arginine.
Amino acid coded for by the codons UUU or UUC?
Phenylalanine is the amino acid coded for by the codons UUU or UUC.
What amino acid is coded for by the codon AUC?
The codon AUC codes for the amino acid isoleucine.
What amino acid is coded for by this sequence before the mutation?
The amino acid coded for by the original sequence can be determined based on the codon table. The sequence is comprised of sets of three nucleotides that correspond to specific amino acids, so you would need to convert the sequence into codons and then use the table to identify the amino acid coded for by those codons.
Can an amino acid be coded for by more sequence of three nucleotides?
Yes, an amino acid can be coded for by more than one sequence of three nucleotides. This is due to the degeneracy of the genetic code, where some amino acids are encoded by multiple codons.
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.
Are amino acid that are represented by one codon?
Yes, there are two amino acids that are represented by a single codon. Methionine is coded for by the start codon AUG, and tryptophan is coded for by the codon UGG.
How many codons would be needed to construct a protein that is composed of 45 amino acids?
You would need 135 codons for a protein composed of 45 amino acids. This is because each amino acid is coded for by a sequence of three nucleotides (codon), so you would need three codons for every amino acid.
Interpret the genetic code to determine the amino acid coded for by the condon ccu?
The link below includes a table of codons and their respective amino acids. You can use this to determine the amino acid coded by any three nucleic acid bases. Read down, then across, then find the one you want from that block of four. In the case of CCU, the amino acid is proline.
List the amino acids in the order they would appear in the polypeptide coded for by the mRNA?
The order of amino acids in a polypeptide is determined by the sequence of codons in the mRNA. The genetic code determines that specific codons correspond to specific amino acids. The mRNA is read in sets of three nucleotides (codons), each of which codes for an amino acid, resulting in the correct sequence of amino acids in the polypeptide.
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.
Which amino acid was never coded for?
Several amino acids are not coded for in biology. 20 are. The two standard amino acids are selenocysteine and pyrrolysine. Then there are the numerous non-standard amino acids, which include hydroxyproline and selenomethionine.
The unique 3 base pair structure for an amino acid is called?
The unique 3 base pair structure for an amino acid is called a codon. Codons are specific sequences of three nucleotides in mRNA that correspond to a particular amino acid during protein synthesis.
