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.

Which of the following types of mutation resulting in an error in the mRNA just after the AUG start of translation is likely to have the most serious effect on the polypeptide product?
A frameshift mutation, such as an insertion or deletion of a nucleotide, that occurs just after the AUG start codon is likely to have the most serious effect on the polypeptide product. This is because frameshift mutations shift the reading frame of the mRNA sequence, causing all subsequent codons to be read incorrectly, leading to a completely altered polypeptide sequence.
Where do frameshift mutations occur?
Frameshift mutations occur when a nucleotide or nucleotides are inserted or removed from a DNA sequence, resulting in all subequent reading frames (codons) being shifted by an amount not divisible by three (the width of a codon). These shifted frames will code for different amino acids than before, and will result in the creation of a malformed (and with very few exceptions, unfunctioning) protein.
What type of mutation could result in a much shorter protein than the original gene product?
A frameshift mutation, such as an insertion or deletion of nucleotides, can cause a shift in the reading frame of a gene during translation, leading to a premature stop codon. This results in a truncated protein that is much shorter than the original gene product.
A genetic mutation that causes a codon that should code for a specific amino acid to be changed into a stop codon results in a shortened protein product and is known as?
A premature stop codon mutation, also known as a nonsense mutation. This mutation causes the translation of the protein to be halted prematurely, leading to a truncated and often nonfunctional protein product.
Why do you need to purify the PCR product?
Purifying the PCR product helps remove excess primers, nucleotides, and enzymes that can interfere with downstream applications like sequencing or cloning. It also concentrates the PCR product, reducing the volumes needed for subsequent reactions.

What is the difference between a point mutation and an insertion and deletion?
Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur. If a deletion mutation occurs then the code for the protein is disrupted and the protein product is probably going to be useless to the body and may even cause a disease.

What is dominant negative mutation?
A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
What is the product of mutation?
A mutant.
Is it true point mutations that involve the insertion or deletion of a nucleotide change the reading frame of the genetic message?
Yes. Nucleotides are read in triplet code (i.e. AAA, CCC) and each set of three nucleotides represents an amino acid. Therefore if you had a line of nucleotides, and you removed or added one in the line you would be changing how the code is read. Observe if you had ACGAGUGAU. It is read as ACG-AGU-GAU - which represents threonine-serine-aspartic acid. Now, if we remove the first A, the new code is CGAGUGAU to which the reading frame is - CGA-GUG-AU. This would even change the amino acids the code was describing. It is now - Argenine-Valine and an incomplete third code.
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
