If there was a chain of seven amino acids, how many possibilities are there for different proteins?
Alex17521 [72]
The diversity of proteins is caused by the mRNA codons and DNA. 
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG) 
with that, they only come in 3 nucleotide increments. which is a codon 
one you have a codon, it goes thru tRNA to come out with an amino acid and a bunch of amino acids makes a polypeptide or protein 
It all depends on what the DNA's code says to make... 
DNA says AUG, RNA makes that UAC which is the amino acid tyrosine

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation
