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.

Why was using reverse transcriptase necessary for finding a way to make artificial insulin?
Scientists had to convert information from amino acids to nucleic acids.
What is e 471?
Mono- and diglycerides of fatty acids
The simplest form of a protein is called?
Amino Acids
What type of substance have a pH between 1 and 6?
Acids.
1 glycerol plus 3 fatty acids equals what?
a fat molecule, or a lipid. Two common fats formed are saturated and unstaurated
A codon is a triplet base sequence?
mRNA
What do organisms use to translate codons into amino acids?
tRNA
All triplet combinations of U C A and G except four code for amino acids What do these four code for?
Start and stop codons
How do nucleic provide nucleic acids with specific codes?
Nucleotides are merely the building blocks of nucleic acids like DNA and RNA. The specific order of these nucleotides are read in triplet form (AAC, ATA, etc.) as codons (which code for amino acids), and the combinations of these codons make up genes (which code for proteins).
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 3 codons do not carry amino acids?
There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).
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.
Which type of RNA has amino acids covalently attached?
tRNA - Transfer RNA tRNA binds amino acids through a two step "charging" reaction and brings those amino acids to the ribosome. The reaction is catalysed by the enzyme aminoacyl transferase. There are many different tRNA molecules, at least one for each amino acid, but not necessarily one for every triplet codon. The triplet codons are groups of three RNA bases on mRNA that code for a specific amino acid in a protein, and are matched to the complementary anticodon in tRNA. Through "wobble" it is possible for one tRNA molecule with a single anticodon to bind two triplet codons on mRNA, with a single non Watson-Crick base pair (usually the third base). Without this "wobble", there would have to be 61 different tRNA molecules (there are 64 possible triplet codons, but three of then signal termination and are not recognised by tRNA). With the "wobble", there could be as few as 20, one for each amino acid.
What are the Triplet codes of three bases are the genetic codes used in transmitting genetic information necessary for?
Codons code for a particular amino acid with a triplet of DNA nucleotides.There are 20 amino acids, and 4 nucleic acids. Using a single base you could only code for 4/20, with two bases 16/20, 3 bases 64/20. Therefore 3 bases are necessary to encode all of the possible amino-acids.
The codes for amino acids are called?
codons
Why the sequence of codons should be triplet but not doublet or quadraplet?
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.
