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 would be the effect of a mutation that changed the c of the anticodon to a g?
The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
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.
When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
Why tyrosine is simple amino acid?
It is an nonessential amino acid but I would not call it's structure that simple.
How would the amino acid sequence produced by the mutant strand compare to the amino acid sequence produced by series 1?
one amino acid in the sequence would change
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.
What happens if only one amino acid is coded incorrectly?
If an amino acid is coded incorrectly, then it would change the entire structure of the DNA and could possibly cause a mutation
How can a single point mutation cause a change in the amino acid?
Be cuz he has a lumpy tummy.
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.

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.
Do transcription and translation change from amino acid to nucleic acid?
no
What would be the effect of a mutation that changed the c of the anticodon to a g?
The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
What is meant by a hydrophobic amino acid how does it behave around water?
A "hydrophobic" amino acid is an acid that "fears" water. When in contact with water, the hydrophobic amino acid will cause that section of protein to stay away from water.
Which amino acid cause curly hairs?
Cysteine.
What is a genetic mutation that does not result in a change in the amino acid sequence of the resulting protein?
It is neutral mutation. Codons are made up of 3 base pairs. This gives 64 different combinations, but there are only 20 amino acids, so some different codons will code for the same amino acid. When the base pair that is changed doesn't cause a change in the amino acid it codes for, then ultimately nothing happens
