What else can I help you with?
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
Synthesis of a defective protein may result from an alteration in?
the DNA sequence coding for the protein, leading to a mutation. This mutation can cause a change in the amino acid sequence, affecting the protein's structure and function. Defective protein synthesis can also result from errors in the transcription or translation processes.
Can a point mutation be frameshift mutation?
No
Which sequence best represents the correct order of events involved for this mutation to affect the traits expressed by this cell?
Mutation occurs in the DNA of the cell. Mutation leads to changes in the sequence of amino acids in a protein. Altered protein function affects the traits expressed by the cell.
What is it called when DNA replication messes up?
One ma be born with physical, and or mental illness. Such as fragile X syndrome.
How do you know if a mutation changes the final protein?
You can determine if a mutation changes the final protein by analyzing the DNA sequence to see if the mutation alters the amino acid sequence of the protein it encodes. This can be done through bioinformatics tools or laboratory experiments such as protein expression or functional assays. Additionally, comparing the mutated protein's structure and function to the wild-type protein can also help assess the impact of the mutation.
What describes a mutation that occurs within a gene?
A mutation that occurs within a gene is known as a gene mutation. This type of mutation can involve changes in the DNA sequence, such as substitutions, insertions, or deletions of nucleotides. These alterations can affect the protein encoded by the gene, potentially altering its function, stability, or expression levels. Depending on the nature of the mutation, it may lead to neutral, beneficial, or harmful effects on the organism.
How does a mutation in a gene affct the order of DNA bases?
A mutation in a gene involves a change in the sequence of DNA bases, which can occur through substitutions, insertions, or deletions. This alteration can affect the amino acid sequence of the protein encoded by the gene, potentially altering its structure and function. Depending on the nature of the mutation, it can lead to beneficial, neutral, or harmful effects on the organism. In some cases, mutations can also disrupt regulatory elements, affecting gene expression.
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.
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
Gene mutation in which only 1 condon is affected?
A point mutation, specifically a substitution mutation, is when only one nucleotide base is altered in a gene sequence, affecting one codon. This can result in a change in the amino acid encoded by that codon in the mRNA, impacting the protein produced by the gene.
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
What is a chromosomal mutation?
A chromosomal mutation is a change in the structure or number of a chromosome. This can involve rearrangements, deletions, duplications, or inversions of genetic material within a chromosome. These mutations can lead to genetic disorders or affect an individual's development and health.
Do mutations always alter the encoded protein structure and function?
No. Since a mutation in the DNA may not necessarily result in a change to the encoded amino acid in the protein sequence, it is entirely possible. Further, the protein function will likely not change when an amino acid is replaced with one of similar chemical properties. Sometimes it does, sometimes it doesn't. This is the field that molecular evolutionary biologists study.
If a nucleotide pair were removed from a gene what would be affected?
If a nucleotide pair were to be removed from a gene, it would cause a frameshift mutation. This would alter the reading frame of the gene, leading to a change in the amino acid sequence of the protein encoded by that gene. This could potentially result in a nonfunctional or altered protein.
When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
What is a A genetic mutation that does not result in a change in the amino acid sequence of the resulting protein is called?
a silent mutation.
