How can only four bases in RNA carry instructions for 20 different amino acids?

∙ 11y ago
The properties of proteins are determined by the order in which different amino acids are joined together to produce polypeptides.
The genetic code is read three letters at a time, so that each "word" of the coded message is three bases long.

∙ 12y agoan amino acid is decoded by 3 nucleotides - so in theory we could encode 43 = 64 different amino acids.
But nature has decided to give some of this 64 tripletts the same meaning and so we get by with 20 biogen amino acids. The advantage with only 20 amino acids is, that only about 70% of all mutations will have an effect in protein folding.

∙ 14y agoRNA is made up of amino acids (just like DNA) so they carry the codes by just simply containing the different amino acids.

How can only 4 bases in rna carry instructions for 20 amino acids?
Transfer RNA comes in sets of three bases. You can arrange four different things into a large number different sets of three. Each combination of bases in Transfer RNA codes for a different amino acid.
How many bases are needed to make 3 amino acids?
One codon is 3 bases long - this codes for one amino acid. Therefore you would need 9 bases (3 codons) to make 3 amino acids.
How many amino acids can a sequence of DNA bases code for?
20
How does ethanol denature proteins?
Proteins can be denatured by: - high temperatures (which break weak intermolecular bonds between the amino acids, and making the protein denature) - acids or bases (which react with the NH2 and/or the COOH group of the amino acids in the protein, affecting the proteins shape) - by heavy metals - by some organic solvents (which do as acids and bases) - amongst others...
How can there be so many different types of proteins when there are only 23 different amino acids?
Proteins are really very diverse in terms of their amino acid composition. Proteins are coded in the DNA, the sequence of DNA (A, T, G, C) determines the fate of amino acids that join together to form a protein. so the bases of the DNA can make a diverse group of proteins. normally proteins from a same family (for example antibodies or kinases) share a conserved domains or amino acids although they differ in their specificity and function.
How many amino acids can a sequence of 24 DNA bases bases code for?
20
Instructions on dna that code for specific proteins or traits?
Yes. The sequence of nitrogen bases in DNA determines the sequence of amino acids in a protein. The sequence of amino acids determines the structure and function of a protein.
If each triplet of nitrogenous bases three bases on DNA codes for a specific amino acid how many amino acids will your original DNA model code for?
There are 64 different triplet combinations of base pairs, which code for 22 different amino acids.
How can only 4 bases in rna carry instructions for 20 amino acids?
Transfer RNA comes in sets of three bases. You can arrange four different things into a large number different sets of three. Each combination of bases in Transfer RNA codes for a different amino acid.
Nucleic acids can be distinguished from proteins by?
Nucleic acids are the building blocks of DNA and RNA.The five nucleic acids are:3 pyrimidine bases: Cytosine and Thymine (or Uracil in RNA) next to2 purine bases: Adenine and Guanine. None of them contains an amino group which is essential in protein formation of amino acids.Proteins are built of the building blocks called amino acids. (there are about twenty different amino acids)
How many bases needed to specify three amino acids?
i think nine bases are needed for three amino acids because i think it takes three bases to make one amino acid
What do three bases form?
amino acids
What determines the sequence of amino-acids in a protein?
The DNA carries the instructions for protein synthesis. These instructions are copied onto mRNA, which then travels to the ribosome. At the ribosome, the mRNA is translated into the correct sequence of amino acids.
How many bases are required to be in a codon to specify twenty different amino acids?
There are a total of three bases that make up a codon.
Why must bases be grouped in triplents in order to represent amino acids?
Because to make up a codon you need to have amino acids which consist of three bases.
Amino acid as acids and bases?
Amino acids are organic molecules which proteins are build from. There are twenty. However there is two amino acids which are acidic: Aspartic acid and glutamic acid.
How many amino acid sequences can be made from four amino acids?
There are 20 common amino acids (pre-modification). In a set of any four, each one could be one of 20, meaning there are 204 possible combinations: 160,000. If the question was meant to be "how many amino acids can be made from 4 triplet codons then the answer would still be exactly the same. Even though there are 4 bases, meaning there are 64 different codes possible, there are still only 20 amino acids available. If the question was meant to be "how many amino acids can be made from 4 bases" you can only make one (which could be any of 20 different residues), as you need three bases to code one amino acid. See the related question below for a listing of the types of amino acids.
