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.
Is amino acid the basic unit of life with respect to chemistry?
Well, there are technically four macromolecules essential to life...they are the lipids, nucleic acids, proteins, and carbohydrates. Amino acids correspond to the proteins, so yes, they are a basic unit of life. However, they are not the only basic unit, because there are others. See, life could not exist as we know it without amino acids, but couldn't with justamino acids as well.
Why does mrna mutation affect the amino acid sequence?
The codon UGU codes for the amino acid Cysteine. The codon UGG codes for the amino acid Tryptophan. Therefore the mutation will cause the amino acid Cysteine to be replaced with Tryptophan. These amino acids are quite different, and the final shape of the protein could be changed as a result. This could affect the function of the protein.
How do you extract amino acids from plants?
by decomposing its proteins. A protease enzyme which cleaves peptidic bonds non-specifically could be used.
What is the maximum number of amino acids that could be coded for by a sextion of mrna with the sequence guucagaacugu?
A codon is three bases long - so this section of mRNA would have 4 codons; UGA-UUC-AGU-AAC.Each codon relates to a specific amino acid (but several codons can code for the same amino acid, for example both UUU and UUC code for the amino acid Phenylalanine).Normally if you have four codons, such as this section of mRNA, the maximum number of amino acids you could have would be four. However, the first codon in this section, UGA, is actually a STOP codon. This means that when the ribosome reaches this codon, no further amino acids will be joined.This means that no amino acids could be coded for with this section of mRNA. (If the order of the codons was reversed, making the STOP codon last, then the answer would be three).
Could a compound that contains carbon hydrogen and oxygen be a protein?
No, proteins are chains consisting of amino acids. Amino acids contain nitrogen.
How many amino acids could be found in the human body?
There are twenty common protein amino acids in your body, of which half can be formed in the cells. The remainder need to be consumed in our diet, as our body cannot make them, yet they are still vital. There are 2 other amino acids very ocassionally used in proteins (only one in humans) meaning that are 21 different protein amino acids in humans. Some biological pathways use other types of amino acids not found in proteins. There are at least six additional ones found in humans, but it would be difficult to determine an exact number.

Do amino acids consist of the amine group?
In short, no. Amino Acids are made up of molecules. Groups of amino acids form proteins. DNA is made up of nucleotides. (Similarly to Amino Acids, nucleotides are made up of molecules.)
What is the theoretical number of different proteins that you could make from 50 amino acids?
20^50
Is hydrogen present in amino acids?
Yes Amino acids are made up of an amino group which has 2 hydrogen atoms and a carboxyl group which also has 2 hydrogen atoms. It then has other groups attached to it which could have many many more hydrogen atoms added to it
Who discovered that a variety of amino acids and organic acids could be produced in the laboratory in a reducing atmosphere with electrical sparks?
the answer is Stanley Miller
How can only four bases in RNA carry instructions for 20 different amino acids?
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.
Why is it possible to have thousands of different types of proteins with only 20 amino acids?
There are many different combinations of amino acids and proteins and peptide bonds.
What does the body do with excess amino acids?
Deamination occurs. An amine group is removed from the amino acids, making ammonia. This ammonia is then converted to urea in the ornithine cycle. Search for 'deamination' on Wikipedia. That should cover it :)
Are amino acids harmful to people under eightteen?
Acids are harmful to everyone! They will tear up your stomach lining and everything else in your digestive system. Amino acids are even worse because they are very acidic and foreign, and your body can't handle them. Amino acids are also the building blocks of cancer, so even if you could survive ingesting them, you will contract cancer in less than 5 years.
