A change to one amino acid in a protein can result from a mutation in the DNA sequence that codes for that protein. This can occur through various types of mutations, such as a missense mutation, where a single nucleotide change leads to the substitution of one amino acid for another. Depending on the properties of the new amino acid, this alteration can affect the protein's structure and function, potentially leading to changes in biological activity or stability. In some cases, such changes can have significant impacts on an organism's phenotype or health.

Which amino acid chain will be formed by the codon AAU?
There would be no change. Both UAC and UAU indicate a tyrosine to be the next amino acid in a polypeptide.Sources:uauuac-biochemistry
What change to this sequence would indicate a silent mutation?
A silent mutation occurs when a change in the DNA sequence does not alter the amino acid sequence of the resulting protein. This can happen through a substitution of a nucleotide that still codes for the same amino acid due to the redundancy of the genetic code. For example, if the original sequence is "GAA" (which codes for glutamic acid) and it changes to "GAG," this would represent a silent mutation since both codons code for the same amino acid. Thus, the change in the sequence that doesn't affect the protein's amino acid sequence indicates a silent mutation.
Which type of mutation would only affect one amino acidwhich type of mutation would only affect one amino acid?
A missense mutation is the type that would only affect one amino acid in a protein sequence. This occurs when a single nucleotide change in the DNA sequence results in the substitution of one amino acid for another in the corresponding protein. This alteration can potentially impact the protein's function, depending on the role of the altered amino acid. Other mutations, like silent or nonsense mutations, do not affect the amino acid sequence in the same way.
What would be the amino acid code for GAG?
The amino acid code for the mRNA codon GAG corresponds to the amino acid Glutamic acid (Glu). In the genetic code, GAG is one of the codons that specifies this particular amino acid.
What type of mutation in the DNA leads to a single change in the amino acid sequence of the protein?
Yes, it already has by changing the amino acid you have a mutation. That one amino acid counld be in the active site of an enzyme and that one amino acid being changed could result in loss of function or reduction in function of the enzyme. Sickle cell animea is caused by a single such amino acid substiution.
Infer why base substitutions in the third position are least likely to cause a change in the amino acid for which it coded.?
In figure 12.14 it shows that sometimes when you change the third base it will still code for the same amino acid. This is because since there is already 2 bases that are correct, even if the third base would change it would still code for the same amino acid.
How can a single point mutation cause a change in the amino acid?
Be cuz he has a lumpy tummy.
What happens if only one amino acid is coded incorrectly?
If only one amino acid is coded incorrectly in a protein sequence, it may result in a missense mutation. This could potentially lead to a change in the structure and function of the protein. The impact of the mutation would depend on the specific amino acid involved and its location within the protein.
What would happen if the concentration of a particular amino acid is greater than the Tm?
If the Tm for a particular amino acid has been exceeded, all the filtered amino acid will fail to absorb. This will cause the excess to secrete into the filtrate.
Which amino acid chain will be formed by the codon AAU?
There would be no change. Both UAC and UAU indicate a tyrosine to be the next amino acid in a polypeptide.Sources:uauuac-biochemistry
Why is it that some point mutations can cause severe genetic diseases while others have no noticeable effects?
There are three main types of point mutations: nonsense, missense, and silent. Nonsense mutations code for a stop instead of the intended amino acid, which cuts short the protein and can cause problems. Missense mutations code for a different amino acid than the one intended and can cause problems. Silent mutations, on the other hand, can, while they make a change in a specific base, still code for the same amino acid. Also, they could code for a different amino acid but cause no change in the overall function of the protein. In this case, there would be no noticeable effects due to the mutation.
How does a mutation change a codon for one amino acid into a different codon for the same amino acid?
A mutation can change a codon for one amino acid into a different codon for the same amino acid through a process called silent mutation. This type of mutation occurs when a change in the DNA sequence does not alter the amino acid that is coded for, resulting in the same protein being produced.
Do transcription and translation change from amino acid to nucleic acid?
no

Which amino acid cause curly hairs?
