How is it possible for gene with a mutation in coding region to encode a polypeptide with the same amino acid sequence as the nonmutant gene?
If the mutant codon still codes for the same amino acid (a silent mutation).
For example:
GUU, GUC, GUA and GUG all code for the amino acid Valine.
So if the mutation changed the codon from GUU to GUA - Valine would still be produced and therefore the polypeptide will be identical.
What else can I help you with?
Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
What kind of mutation is tag ctt ggc at?
The sequence "tag ctt ggc" provided does not represent a specific mutation. A mutation would involve a change in a specific base or bases within a DNA sequence. Without further context or details, it is not possible to determine the type of mutation.
What is a mutation in a DNA sequence called?
a change in the DNA sequence is a mutation, so I'm not sure what you're asking
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
How do you make a 10 codon sequence for a polypeptide?
To create a 10 codon sequence for a polypeptide, you would need to transcribe a DNA sequence into an mRNA sequence. Each codon consists of three nucleotides. Look for the start codon (AUG) to begin the sequence and then continue adding codons until you have 10 in total.
If an enzyme is absent during polypeptide production a mutation can occur?
Yes, if an enzyme necessary for polypeptide production is absent, the process may be disrupted. This could potentially lead to errors in translation, such as misincorporation of incorrect amino acids, which can result in a mutation in the polypeptide sequence.
Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
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.
What kind of mutation is tag ctt ggc at?
The sequence "tag ctt ggc" provided does not represent a specific mutation. A mutation would involve a change in a specific base or bases within a DNA sequence. Without further context or details, it is not possible to determine the type of mutation.
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 the effects of mutation?
A mutation is a permenent in DNA sequence of a gene,mutation in a gene's DNA sequence can alterthe aminoacid sequence of the protein encodedby the gene.
How can a mutation in DNA base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
Can a point mutation be frameshift mutation?
No
What is a mutation in a DNA sequence called?
a change in the DNA sequence is a mutation, so I'm not sure what you're asking
Is A polypeptide is a sequence of proteins or amino acids?
A polypeptide is a chain of amino acids linked together by peptide bonds. It is not a sequence of proteins, but rather a precursor to protein formation. When a polypeptide chain folds into a specific structure, it becomes a functional protein.
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
