So the correct answer is Either an insertion or a deletion of a base. So the correct answer is Either an insertion or a deletion of a base.

It depends on the nucleotide sequence and the kind of insertion or deletion that has occurred.
. A frameshift mutation is anything that puts the regular order of 3 nucleotides a codon out of its norm. A frameshift mutation could result from A a base insertion only B a base deletion only C a base substitution only D deletion of three consecutive bases E either an insertion or a deletion of a base. A frameshift mutation occurs when nucleotides are inserted into or deleted from the DNA and cause a shift in the reading of mRNA codons.
Gene mutations textbfGene mutations Gene mutations. Circle each correct answer. The gene expression is performed by codons either by insertion or deletion of a base which can change the reading frame of sequencehence the frameshift mutation occurs.
A Deletion frameshift mutation occurs when one or more nucleotides in a nucleic acid are deleted causing a shift in the nucleic acids reading frame or reading frameshift. Either an insertion or a deletion of a base. Either an insertion or a deletion of a base.
O A tRNA B DNA C ribosomes. Frameshift mutations are insertions or deletions of nucleotides in DNA that change the reading frame the grouping of codons. A frameshift mutation could result from a.
A mutation that results in a change in the codon reading pattern could result from the deletion or insertion of a base. If these things happen then you get a frameshift. A frameshift mutation can throw off all of the nucleotide that follow in a DNA sequence making them particularly likely to lead to significant.
A frameshift mutation could result from a. This occurs in the gene - not outside of the coding sequence. A a base insertion only B either an insertion or a deletion of a base 0 a base substitution only CD a base deletion only Which component is not directly involved in translation.
Question 49 15 points Which of the following types of mutations could result in a frameshift mutation. 1 frameshift mutation is another name for this mutation. Frameshift mutations caused by indel mutations meaning insertion or deletion mutations.
Deletion of three consecutive bases. These mutations shift the way the DNA is read. 17 in human NOTCH2 genes were not found because they were not annotated in Ensembl release 88 30 in mouse 31 in zebrafish and 2 in fruit fly Table 1For each pair of duplicates we searched for.
A base insertion only. Caused by mutagens that can either come in the form of radiation or chemicals produce a permanent alteration of one gene. Mutations summary table.
There is no difficulty with the ribosome A-site nor does the presence of a single extra nucleotide automatically increase polypeptide length. Single change in DNA code produces stop codon prematurely terminates protein synthesis. Deletion is a more typical method for causing a frameshift mutation which causes an altered reading frame.
The sequence of three nucleotides of either DNA or RNA is known as a codon. ATG AAA A TT CTG CCC T. Correct option is D The sequence of three nucleotides of either DNA or RNA is known as a codon.
A base substitution only. Insertion and deletion result in a frameshift mutation. A base deletion only.
A frameshift mutation is a mutation caused by an insertion or deletion which causes a shift in the translational reading frame. Frameshift mutations can either result in an abnormally long or prematurely truncated protein. Frameshift mutations have a more dramatic effect on the polypeptide.
We identified in total 80 pairs of duplicate genes with frameshift mutations between them in these species see Materials and Methods. But also that following infection by PrP Sc PrP deposition can be found in extraneural tissues such as heart. Likewise insertions deletions and point mutations can all generate a nonsense codon mutation directly.
View the full answer. Frameshift mutations are deletions or additions of 1 2 or 4 nucleotides that change the ribosome reading frame and cause premature termination of translation at a new nonsense or chain termination codon TAA TAG and TGA. This is also known as a.
How does a frameshift mutation in the gene coding for the enzyme hexosaminidase A result in Tay-Sachs disease. Mistake in the DNA code one of the DNA base pairs is changed. Loss of a single basepair perhaps the A in bold.
A point mutation could result from A a base insertion only B a base deletion only C a base substitution only D deletion of three consecutive bases E either. Step 1 1 of 4. Which of the following can result in a frameshift mutation.
Addition of one or more nucleotide base pairs into the DNA sequence. The gene expression is performed by codons either by insertion or deletion of a base which can change the reading frame of sequencehence the frameshift mutation occurs. Frameshift mutations are the result of insertions or deletions that alter the reading frame of the triplet codons thereby altering translation and altering the structure and function of the protein product.
The mutation results in incorrect synthesis of.
