Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
How can a point mutation alter the final structure of a protein?
In a point mutation, one nitrogen base is substituted for the correct base. Since most amino acids can be coded for by more than one codon, there may be no consequence to this mutation. However, sometimes a point mutation results in an incorrect amino acid being added to the amino acid sequence of the protein. This can cause a change in the shape and therefore function of the protein, which can be a harmful mutation. Two genetic disorders caused by a point mutation are cystic fibrosis and sickle cell anemia.
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. This type of mutation can result in changes to the amino acid sequence of a protein, leading to potential functional consequences.
How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.

What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
Why is it possible for a point mutation to have no effect on an individual's fitness?
A point mutation may have no effect on an individual's fitness if it occurs in a non-coding region of the DNA or if it results in a silent mutation that does not change the amino acid sequence of a protein. In these cases, the mutation does not impact the individual's ability to survive and reproduce, so it does not affect their fitness.
Why is is it possible for a point mutation to have no affect on the protein produced?
A point mutation can have no effect on the protein produced if it occurs in a non-coding region of the gene, such as an intron. In coding regions (exons), silent mutations can also occur where the mutation leads to a codon that still codes for the same amino acid, preserving the protein's function. Additionally, some amino acid substitutions might not impact the protein's structure or function due to redundancy in the genetic code or similarities in amino acid properties.

What does a point mutation cause?
A point mutation is when a single nucleotide switches from G to C or from A to T, or when a single nucleotide is deleted or inserted. It's unlikely for any single mutation to have a significant effect, but the effects that could occur could be anything, ranging from eliminating or altering protein synthesis of a particular protein to altering the regulatory function of a stretch of DNA and thereby affecting the embryological development of an organism.
What is the difference between point and non-synonymous mutation?
A point mutation is a change in a single nucleotide in the genetic code, while a non-synonymous mutation is a type of point mutation that causes an amino acid change in the resulting protein. Non-synonymous mutations can affect the function of the protein, while synonymous mutations do not change the amino acid sequence.

A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
A mutation that involves one or a few nucleotides is called a?
Sorry to burst the persons bubble that said frameshift mutation but its wrong. Point mutation-gene mutation involving changes in one or a few nucleotides. point mutation
Is it possible for a function to have a negative semidefinite Hessian matrix at a critical point?
Yes, it is possible for a function to have a negative semidefinite Hessian matrix at a critical point.
