If we take duplet code for four bases then would be 16 codon which are not enough for 20 amino acids If the code is triplet it will give 64 codons their will be excess of 44 codon and therefore more then one codons are present for same amino acid. The excess will be still greater if more then three letter words are used. In the quardruplet code there will be 256 possibilities which is not possible. It was proved by NIRENBERG, KHORANA & HOLLEY(1968), they used in vitro system for the synthesis of a polypeptide using an artificial mRNA molecule.
What else can I help you with?
Define triplet code?
Triplet code refers to the sequence of three nucleotides (codons) in DNA or RNA that specify a particular amino acid during protein synthesis. Each triplet in the sequence corresponds to a specific amino acid, allowing the translation of genetic information into proteins.
What are the complement of the codons and are found on the opposite side of he rna?
tRNA (or transfer RNA) molecules contain an anti-codon loop that contains within it a triplet complementary nucleotide sequence to that of the codon. This triplet is called the anti-codon
The triplet codes needed to specify a specific polypeptide chain are found in the?
The triplet codes needed to specify a specific polypeptide chain are found in the mRNA (messenger RNA) during the process of translation. These triplet codes, known as codons, determine the sequence of amino acids that will be incorporated into the polypeptide chain.
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
How many codons are needed to code for a protein that has 50 amino acids?
Since each amino acid is encoded by a specific triplet of nucleotides (codon), you would need 50 codons to code for a protein that has 50 amino acids. Each codon corresponds to one amino acid, ensuring the correct sequence is produced during protein synthesis.
Define triplet code?
Triplet code refers to the sequence of three nucleotides (codons) in DNA or RNA that specify a particular amino acid during protein synthesis. Each triplet in the sequence corresponds to a specific amino acid, allowing the translation of genetic information into proteins.
The order of bases in a molecule of mRNA is determined by the sequence?
The base sequence of mRnas is 'determined by the base sequence of nucleotides in Dna.' The base sequence is transformed into information via the triplet codons of The Genetic Code.
A codon is a triplet base sequence?
mRNA
The triplet code means that 64 codons translate into only 20 amino acids. What are the additional 44 codons used for?
The triplet code means that 64 codons translate into only 20 amino acids. The additional 44 codons are not used for anything, but they are rather a redundancy in the code.
What are the complement of the codons and are found on the opposite side of he rna?
tRNA (or transfer RNA) molecules contain an anti-codon loop that contains within it a triplet complementary nucleotide sequence to that of the codon. This triplet is called the anti-codon

The triplet codes needed to specify a specific polypeptide chain are found in the mRNA (messenger RNA) during the process of translation. These triplet codes, known as codons, determine the sequence of amino acids that will be incorporated into the polypeptide chain.
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 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.
Nucleotides are used to make up units of three?
Absolutely Yes, Life Depends Upon It. Nucleotides grouped in 3's are called ' triplet codons '. The four nucleotides, ATC&G, read as triplet codons, determine the order of amino-acids that are sequentially added to a nascent (growing) protein chain. See Proteins and Dna.
What is the importance of the codons in protein synthesis?
A codon is the triplet sequence in the messenger RNA (mRNA) transcript which specifies a corresponding amino acid (or a start or stop command). An anticodon is the corresponding triplet sequence on the transfer RNA (tRNA) which brings in the specifieds amino acid to the ribosome during translation. The anticodon is complementary to the codon, that is, if the codon is AUU, then the anticodon is UAA. No Thymine's in mRNA. It's replaced by Uranine
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
Where are serine and alanine located in the protein chain?
Wherever their associated triplet codons occur within the associated mRna's.
