How many natural occurring amino acids does the genetic code allow for?
There are 64 possible triplets. At least one of the triplets needs to be a stop codon, so theoretically 63 different amino acids can be coded for. In practice, there's some redundancy, and in humans all codons are either stop codons or translate to one of twenty amino acids.
Is it impossible for an amino acid to be specified by more than one codon?
No, it is possible for an amino acid to be specified by more than one codon due to the redundancy in the genetic code. This phenomenon is known as degeneracy.
Are some aminoacids not specified by any codons?
No, all 20 standard amino acids used in protein synthesis are specified by at least one codon. Each codon on the mRNA corresponds to a specific amino acid during translation, as determined by the genetic code.
A codon is a triplet base sequence?
mRNA
How many codons are needed to specify three amino acids 6 or 9?
Three amino acids can be specified with at least 9 codons. Each amino acid is specified by a sequence of 3 nucleotides called a codon, so 3 amino acids would require 3 codons (3 codons for each amino acid = 9 codons total).

How do amino acids specify codons?
Nucleutoides.
How many codons specify the twenty types of amino acids?
There are 61 codons that specify the twenty types of amino acids, since multiple codons can code for the same amino acid due to the redundancy of the genetic code.

No, it is possible for an amino acid to be specified by more than one codon due to the redundancy in the genetic code. This phenomenon is known as degeneracy.

No, all 20 standard amino acids used in protein synthesis are specified by at least one codon. Each codon on the mRNA corresponds to a specific amino acid during translation, as determined by the genetic code.
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.
How many amino acids can a sequence of DNA bases code for?
20
The sequences of amino acids that make up a protein molecule are specified by?
The sequences of amino acids in a protein molecule are specified by the genetic code present in an organism's DNA. The information from DNA is transcribed into RNA, which is then translated by ribosomes into the specific sequence of amino acids that make up the protein. Each set of three nucleotides in the RNA sequence, called a codon, corresponds to a specific amino acid.
A codon is a triplet base sequence?
mRNA
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.
What 3 codons do not carry amino acids?
The three codons that do not carry amino acids are UAA, UAG, and UGA. These codons are known as stop codons and signal the end of protein synthesis.
How do the nitrogen bases along a gene serve as a genetic code?
Nitrogen bases along a gene form codons, which are three-base sequences that code for specific amino acids during protein synthesis. This sequence of codons provides the genetic instructions that determine the sequence of amino acids in a protein. The genetic code is universal, meaning that the same codons code for the same amino acids in nearly all organisms.
