Based on the 20 amino acids found in proteins, there are 6840 possible variations in a polymer composed of just three amino acids.
<h3>What are amino acids?</h3>
Amino acids are the molecules from which protein molecules are made from.
There are 20 common amino acids from which protein molecules are built up from.
The amino acids are joined one to another in the protein by peptide bonds.
In a polymer composed of three amino acids, the possible variations are calculated by permutation.
The possible variations are 20 permutation 3.
nPr = n!/(n - r)!
where n = 20 r = 3
nPr = 20!/(20 - 3)!
nPr = 6840
Therefore, there are 6840 possible variations in a polymer composed of just three amino acids.

Answer:
The correct answer is - 2 type A : 1 type AB : 1 type B
Explanation:
The pattern of the inheritance in the ABO blood group system is the example of the multiple alleles and codominance. There are three alleles in this sytem that determines what blood group would be in an indvidual that are; IA, IB, and IO. The allele IO is a recessive allele to both IA, and IB alleles whereas IA and IB are show codominance when present in heterzygous condition.
Genotype of a person with “A” blood group can be IA
IO or IA
IA but as it is given that the mother of the male with A bglood group is O blood group which means there must be a IO allele would be present in the male too so the genotype would be IAIO.
The genotype of AB blood group mother would be IAIB as shows codominance. so the cross between these woulde be as follows:
IA
IO x IA
IB
Gametes :
IA IO
, and IA IB
IA IO
IA IAIA IAIO
IB IAIB IBIO
phenotypic ratio = 2 A group : 1 AB group : 1 B group
Answer:
The amino acids are important for the growth of almost all the organisms from the yeast to humans. While culturing yeast at the lab conditions, proper growth media is required.
The yeast is not able to make leucine. When this yeast is grown in the YPD plate, the growth of yeast is supported. The YPD consists of peptones, glucose and yeast extract. This media is enriched with all the components required for the yeast growth. The SD plate is also known as synthetic plate that do not contain the essential amino acids and consists of only nitrogenous bases. The mutant yeast will unable to grown in this media as leucine is not available. The mutant can be grown on this plate if the plate is supplied with the external media consisting of leucine and other essential amino acids.
Its .. Nervous tissues i think i still remember cause i had this question on an exam and i got it right lol ..
- But hoped i helped you out any .. if anymore help is need just ask me then .
