What impact could a point mutation do?
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
How many amino acids would this protein have if a mutation occurred and the 7th dna base pair of the dna strand was changed from a-t to t-a?
There would be no change in no. of amino acids as this mutation is miscense mutation, no . of amino acids changes with frame shift mutations .
Most genetic disorders results from a mutation that changes the amino acid sequence in a?
Protein
What is a A genetic mutation that does not result in a change in the amino acid sequence of the resulting protein is called?
a silent mutation.
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.

Which type of mutation does not change the amino produced?
Well consider the substitution of one hydrophillic amino acid for another hydrophillic amino acid. This type of mutation changes nothing but a molecular marker. or Silent

Describe 4 ways mutation can occur without change its phenotype?
The phenotype will not be affected with silent mutation and synonymous mutation. It also can be mutated in a coding region that changes the amino acid or changes the protein to be folded.
What is a Missence mutation?
A mutation that causes the code for the wrong amino acid (apexvs.com)
What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.

What produces a nonsense mutation?
A nonsense mutation is a genetic mutation in a DNA sequence that leads to the appearance of a stop codon where previously there was a codon specifying an amino acid. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop codon, which is also called nonsense codon because it does not code for an amino acid and instead signals the end of protein synthesis. Therefore, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, this premature stop codon results in the production of a shortened, and likely nonfunctional, protein.
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
