A mutation
Which is worse chromosome mutation or point mutation?
Chromosome mutations are generally considered more severe than point mutations because they involve changes in a larger portion of genetic material, potentially affecting multiple genes and leading to more significant impacts on an organism's phenotype. Point mutations, on the other hand, involve changes in a single nucleotide and may have smaller-scale effects.
Do mutations always cause pheynotypic changes?
No, because of the redundancy in the genetic code (several base triplets or codons code for the same amino acid) a point mutation, for instance, (a change in one base) may have no effect on the amino acid sequence in the protein, and so no effect on the expressed phenotype.
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.
Why is point mutation dangerous?
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.
What cell mutation does not impact the phenotype of the organism because the protein remains unchanged?
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.
Could a mutation affect phenotype?
Yes, a mutation can occur without affecting the phenotype at all. For example, a point mutation may change a nucleotide in a codon, but sometimes, the codon can still code the same amino acid, so the mRNA strand can still make the same protein.
Why does an insertion mutation usually cause defects during protein synthesis than a point mutation?
Insertion mutations can affect many amino acids in the protein.An insertion mutation usually causes more defects during protein synthesis than point mutation because an insertion mutation will affect many amino acids in the protein.
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.

What is a mutation that affects the gametes of an organism?
A point mutation is a mutation that can affect the gametes of an organism. This type of mutation involves a change in a single nucleotide in the DNA sequence, which can result in altered genetic information being passed on to offspring.
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.
How many amino acids are affected from point mutation?
A point mutation can affect the protein in a different ways. If the point change causes a silent mutation then it doesnt affect at all. When the point nucleotide change make a different amino acid, then it may alters the function of protein. If it make to forma a stop codon (TAA, TAG, TGA) then the protein synthesis stops at the point where it is changed.
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
