There are 64 DNA codons (possible sequences of the 3-letter nucleotide bases A - adenine, T - thymine, which is replaced by U - uracil in RNA, C - cytosine and G - guanine) but only 20 possible amino acids because of the possibility of mutations that would replace one nucleotide base with another.
For example, both AAA and AAG code for the production of lysine. This means that if a codon sequence was originally AAA and a mutation or an error in copying the DNA strand placed guanine in place of the final adenine, lysine would still be coded for. Though there are many possible errors that would cause an incorrect amino acid to be produced - for example, if cytosine was in place of the final adenine, asparagine would be coded for - having more than one codon per amino acid reduces the chances of a wrong amino acid being produced.
Proteins can include up to 20 different amino acids because there are only 20 L-α-amino acids available to create them.
Chains that are less than 40 amino acids long are generally referred to as "polypeptides" or "peptides". Chains over 40 amino acids long are generally called proteins.
because there are four different nucleotides possible to make up a three-codon amino acid. 4x4x4 aka,(43) is 64
because thats just the way it is and has to be
Amino acids.
Melamine is a protein, which is made of amino acids.
Proteins are formed from the basic units called as amino acids. There are 20 amino acids in the body of human being. You have over 300 amino acids found in the nature.
Even with 20 amino acids, there can be innumerable combinations. Since amino acids can be repeated in the polypeptide chain, it is easy to create a variety of proteins. It must also be taken to account that just one protein is made from around 50 amino acids minimum, which greatly increases the diversity of the protein. Even with just 50 amino acids, the different arrangements can be 3.04*1064, which is a significant amount of proteins that can be made from arrangements of just 50 amino acids.
20 amino acids make up all the proteins in your body.
A protein is a chain of amino acids. Small chains of amino acids are called polypeptides. If the chain is over 20 amino acids long, it is called a protein.
Protein molecules are digested by protease enzymes into one of 20 individual amino acids.
There are nine essential amino acids. A protein is considered to be complete if it contains all nine of these amino acids.
Answer 1The 20 amino acids are the building blocks of proteins.Answer 2You might consider it a protein because it makes up a protein, but it is not actually a protein.
there is only 20 amin acid in our bodies but we only use 11 of them
The number of amino acids/protein differ largely and is characteristic for each protein separately. A protein is composed of amino acids, and the function of the protein depends of the type and order of the amino acids. Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of protein from just the same 20 amino acids.The simplest protein of life, ribonuclease, contains 124 amino acids. The "average" protein, though, contains several thousand amino acids, but those several thousand comprised only about 20 different kinds of amino acids.
It would take 19 peptide bonds to make a protein of 20 amino acids.
No. A protein is defined by its function, as much as its structure. A chain of two amino acids would have no protein-like functions. The smallest known protein is a chain of 20 amino acids, but most have many more, and sometimes consist of multiple chains of amino acids.
Proteins are polymers of amino acids. The monomer of proteins is amino acids. Chains of amino acids are polypeptides and are called proteins if there are more than 20 amino acids in the chain.
amino acids are the monomers for protein
The way you stated your question doesn't make any sense. Proteins are a combination of "amino acids". Amino acids are monomers of proteins. There are 20 amino acids that arrange themselves differently to make a single protein.
