how many possible combinations of amino acids are there?
527885
In general there are combinations of aminoacids. This number grows very, very fast. In fact, exponentially fast. The possible combinations of 300 aminoacids (a middle-size protein), for example exceed .

How many possible combinations can arise? The fusion of two gametes (each with over 8 million possible chromosome combinations from independent assortment) produces a zygote with over 64 trillion diploid combinations (this is without considering crossing over!)

['When it comes to protein, there are 20 different amino acids that make up each molecule of protein, and these are split into 2 categories: Non-Essential Amino Acids and Essential Amino Acids (EAAs)', 'There are two main categories (or sources) of proteins – animal and plant based.']

Consider the possible combinations when that sperm cell is united with an egg cell that is also 1 of 8,000,000 combinations. The resulting diploid zygote is one of over 64,000,000,000,000 possible combinations of the genes of the two parents.

1 Answer. Between two amino acids , one water molecule is eliminated and a peptide bond is formed. When 500 amino acids are joined to form a polypeptide , 250 molecules of water will be removed.

There are 20 different amino acids which make up proteins. Each amino acid consists of a central carbon. The central carbon is bonded to an amine group ( NH2 ), a carboxyl group (COOH), a hydrogen atom and an R group.

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. The simplest, and smallest, amino acid is glycine for which the R-group is a hydrogen (H). ... This chart shows the chemical structures of the 20 amino acids that make up proteins.

In this example, there are four possible genetic combinations for the gametes. With n = 23 in human cells, there are over 8 million possible combinations of paternal and maternal chromosomes.

The three-letter nature of codons means that the four nucleotides found in mRNA — A, U, G, and C — can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
472235
The genetic code consists of 64 triplets of nucleotides. These triplets are called codons. With three exceptions, each codon encodes for one of the 20 amino acids used in the synthesis of proteins. That produces some redundancy in the code: most of the amino acids being encoded by more than one codon.
150704
Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.

256 That is correct. In a tetranucleotide block where the nucleotides can appear more than once and the order is random, there can be 256 possible combinations.
275875
-- we're in a position to answer your original question. With 8 items on your menu, the number of possible combinations will be 28 = 256. And if you bought all 8 items, and tried to arrange them in different orders on your tray, the number of arrangements ('permutations') would be 8! = 40320.

The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Answer and Explanation: For any group of 6 numbers and letters, there are a possible 720 different permutations or combinations that can be made.

How many possible gamete combinations are there for an organism that has a diploid number of 8? 24 = 2 X 2 X 2 x 2 = 16 different combinations.

Twenty-two amino acids are naturally incorporated into polypeptides and are called proteinogenic or natural amino acids. Of these, 20 are encoded by the universal genetic code. The remaining 2, selenocysteine and pyrrolysine, are incorporated into proteins by unique synthetic mechanisms.
