Assuming you do not have a typo in your question, a codon is a triplet of adjacent nucleotides in the messenger RNA chain that codes for a specific amino acid in the synthesis of a protein molecule.

A sequence of 3 bases which specifies a particular amino acid during protein synthesis is called a codon

it is located on mRNA

it is always complementary to the genetic code (a sequence of 3 bases in DNA)

A codon is a sequence of three nucleotides. Each codon represents a particular amino acid, or a stop or start signal. Most amino acids can be represented by two or more different codons. The order of the codons determines the order of the amino acids in a protein, which determines the three dimensional structure of the protein, which determines the function of the protein.

Codon refers to a specific sequence comprising 3 adjacent bases found on various strands of DNA or RNA. It helps in the provision of genetic code information for a given amino acid.

How many codons are in aaaugcucguaa?

There are four codons in AAA UGC UCG UAA. A codon is a sequence made of three nitrogenous bases. Codons have particular features, making it possible for them to be start codons, stop codons, introns, or exons.


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.


Are amino acid that are represented by one codon?

yes, but there are amino acids can be represented by many codons.


How do amino acids specify codons?

Nucleutoides.


If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?

A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.


How many codons would be needed to construct a protein that is composed of 45 amino acids?

Each aminoacid is codified by three codons, so by multiplying the 60 by 3, the answer is 180 codons (not counting the stop codon).
