Which type of mutation will have the most evolutionary consequence?
A frameshift mutation will have the most serious effects.A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.Divisible by three is important because the cell reads a gene in groups of three bases.Each group of three bases corresponds to one of 20 different amino acids used to build a protein.If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
Which is more harmful frameshift mutation or point mutation?
point mutations include substitutions insertions and deletions of single nucleotides in DNA. insertions and deletions have a greater effect on proteins than do substitutions because insertions and deletions affect every amino acid that is specified by the nucleotides that follow the point mutation. in contrast a substitution affects a single amino acid. a change in more than one amino acid is more than likely to alter the ability of the protein to function normally than is a change in a single amino acid
What is the impact of a frameshift mutation, where one or more pairs of nucleotides are removed from a gene, on the resulting protein product?
A frameshift mutation, where nucleotides are removed from a gene, can change the reading frame of the gene. This alters the sequence of amino acids in the resulting protein, leading to a non-functional or abnormal protein. This can have serious consequences on the protein's structure and function, potentially causing genetic disorders or diseases.
What are two types of frame shift mutations?
"I believe there is insertion and deletion, (one kind), and substitutions. (the second kind)" This answer is incorrect, the two types of frameshift mutation are insertion and deletion, these both alter the translation reading frame. A substitution point mutation in DNA is referred to as a single-nucleotide polymorphism and does not result in any change to the translational reading frame. insections and deletions are two types of frameshift mutations
9 a DNA segment is changed from -aattagaaatag- to -attagaaatag- this is a?
This mutation represents a deletion of a single nucleotide (A) in the DNA segment. Deletions involve the removal of one or more nucleotides from the DNA sequence, leading to a change in the genetic code. In this case, the deletion results in a frameshift mutation, causing a shift in the reading frame of the genetic code downstream of the deletion site.
Would a frame shift mutation or a substitution impact a protein structure more?
A frameshift mutation typically has a more significant impact on protein structure than a substitution mutation. This is because a frameshift alters the reading frame of the genetic code, leading to a completely different and often nonfunctional protein due to changes in the entire amino acid sequence downstream of the mutation. In contrast, a substitution mutation changes only one amino acid, which may have a minor effect on protein function or structure, depending on the specific amino acid involved and its role in the protein.
In what type of mutation is one base left out?
A one base left out mutation is called a deletion mutation. This type of mutation involves the loss of one or more nucleotides from a DNA sequence, which can lead to a frameshift mutation if not in multiples of three.
What are types of point mutation?
The types of point mutations are: base-pair substitution, insertions, deletions, and frameshift mutations. In base-pair substitution, one nucleotide and its corresponding partner are replaced with another pair of nucleotide. In insertion, nucleotide pairs are added to a gene. In deletion, nucleotide pairs are taken out of a gene. Frameshift mutation happens as a result of insertion or deletion when more or less than three (or a multiple of three) nucleotide pairs are added to or taken from a gene.
Is this mutation caused by a point mutation or frameshift mutation celiac disease?
Celiac disease is primarily associated with specific genetic variations in the HLA-DQ genes, particularly HLA-DQ2 and HLA-DQ8, rather than being caused by a point mutation or frameshift mutation. These variations are typically due to small insertions or deletions that can alter the amino acid sequence, but the disease is more strongly linked to these haplotypes than to a single mutation type. Therefore, while mutations can play a role in the genetic predisposition to celiac disease, it's not accurately characterized solely as a point or frameshift mutation.

Are point mutations more harmful than frame shift mutations?
It depends on the specific context. Point mutations typically involve a change in a single nucleotide, which may or may not lead to changes in the corresponding amino acid. Frame shift mutations, on the other hand, involve the insertion or deletion of nucleotides that can disrupt the reading frame of the gene, potentially leading to more drastic changes in the resulting protein. So, in general, frame shift mutations could be considered more harmful as they have the potential to alter multiple amino acids downstream of the mutation site.
Why does a deletion mutation usually cause more effects during protein synthesis than a mutation?
A deletion mutation typically removes one or more nucleotides from the DNA sequence, which can disrupt the reading frame of the codons during protein synthesis, leading to a frameshift mutation. This alteration often results in a completely different and nonfunctional protein, as the downstream amino acid sequence is altered. In contrast, a point mutation (such as a substitution) may only change a single amino acid or have no effect at all if it occurs in a non-coding region or results in a synonymous codon. Thus, deletions generally have more severe consequences for protein function than point mutations.
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.

What is the difference between a nonsense mutation and a frame shift mutation?
A point mutation is where a single letter is the only thing changed in the DNA sequence. Lets say your phone number (or DNA code) was 483-1839 and you mistakely told someone that your phone number was 483-1835. that one digit is enough to make that person dial the wrong number (or cause a mutation in DNA.) For example suppose your DNA sequence was ACT GCT, a point mutation would just be a change in one of those bases (or letters), so it could end up something like : ACT ACT.EX: GTA CTG CAA-----> (point mutation) -----> GTA GTG CAAA frameshift mutation is generally much more serious and will cause a change all the way down a DNA sequence, making each codon (or every group of three bases) a different sequence, not just in one point or base like a point mutation, that would only slightly change the sequence of a single codon. A frameshift mutation happens not when a DNA base is simply changed, but when a whole base is added or deleted from the sequence of DNA. For example lets suppose your DNA sequence is GTA CCT AGG. In a frameshift mutation a whole base would be added somewhere in that sequence, making it look something like this: GTAT CCT AGG. Since it is impossible though to have 4 bases in a codon, your body would automatically shift every letter down one, even to the next codon in the sequence, to make room for this new base. In the end the final product would look something like this: GTA TCC TAG (with the left over G being the first base in the next codon, and so on).EX: CAG TTC CTG GAA -----> (frameshift muation) -----> CAG TTA CCT GGAAs you can see the frameshift mutation would leave the mutated DNA vastly more different from its parent DNA (that it was replicated from), then a point mutation would, though in both cases the DNA would still be different/mutated. This is because the codons would be more considerbaly changed with the frameshift (where now the sequence in every codon in different), rather than in a point mutation (where only one of the codons would be different).Hope this helps all you HS Bio 1 people like myself out there, or anyone else studying this subject.-- K.J.S
