When when a mutation results in no significant change in the production of a of a functional protein?
When a mutation does not change the result of a normal production of a protein is called harmless. This is because it does no harm to the individual.
What else can I help you with?
A random change in the base sequence of DNA resulting in the production of a defective protein is called?
A random change in the base sequence of DNA resulting in the production of a defective protein is called a mutation. Mutations can lead to changes in the amino acid sequence of a protein, affecting its structure and function.
A mutation in which a single base is added to or deleted from DNA is called what?
A mutation in which a single base is added to or deleted from DNA is called an insertion or deletion mutation, also known as an indel mutation. This can lead to a shift in the reading frame during translation, causing significant changes in the resulting protein sequence and potentially leading to functional consequences.
How does a frameshift mutation impact the function of a protein?
A frameshift mutation can change the reading frame of a gene, causing a shift in the way the genetic code is read. This can lead to a different sequence of amino acids being produced, which can alter the structure and function of the protein. This can result in a non-functional or dysfunctional protein being produced.
What small-scale mutation would be most likely to have a catastrophic effect on the functioning of a protein?
A single-nucleotide substitution causing a missense mutation that changes a critical amino acid in the protein's active site or functional domain is most likely to have a catastrophic effect on the protein's function. This type of mutation can disrupt the protein's structure or its ability to interact with other molecules, leading to severe functional impairment.
What happens in a substitution mutation and how does it impact the genetic code?
In a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can change the amino acid that is coded for, potentially altering the protein that is produced. This can lead to changes in the genetic code, which may result in a different protein being produced or a non-functional protein.
What happens if a ribosome does not read in frame?
If a ribosome does not read the genetic code in the correct reading frame, it can lead to a "frameshift" mutation, where the entire genetic code downstream of the mutation is read incorrectly. This results in the production of a non-functional or truncated protein. Frameshift mutations can have significant effects on the structure and function of the resulting protein.
What is truncation mutation?
Truncation mutation is a type of mutation that results in the premature termination of the protein synthesis process. This leads to the production of a truncated or incomplete protein which may be nonfunctional. Truncation mutations can have serious consequences on the structure and function of the protein.
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.
WhIch best describes the initial change cause by a DNA mutation?
A DNA mutation can lead to changes in the sequence of nucleotides in the DNA, which can alter the instructions for building proteins. These changes can result in the production of a faulty protein or a non-functional protein, which can affect the normal functioning of cells and potentially lead to disease or other conditions.
A random change in the base sequence of DNA resulting in the production of a defective protein is called?
A random change in the base sequence of DNA resulting in the production of a defective protein is called a mutation. Mutations can lead to changes in the amino acid sequence of a protein, affecting its structure and function.
One disadvantage of a genetic mutation in a human cheek cell is that?
It may result in the production of a defective protein
A mutation in which a single base is added to or deleted from DNA is called what?
A mutation in which a single base is added to or deleted from DNA is called an insertion or deletion mutation, also known as an indel mutation. This can lead to a shift in the reading frame during translation, causing significant changes in the resulting protein sequence and potentially leading to functional consequences.
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. This type of mutation can result in changes to the amino acid sequence of a protein, leading to potential functional consequences.
What could be a harmful mutation?
A harmful mutation is one that can disrupt the normal functioning of a gene, leading to the production of a non-functional or altered protein. This can result in diseases or disorders, such as cancer, cystic fibrosis, or sickle cell anemia. Harmful mutations can also impact an individual's ability to survive and reproduce.
How does a frameshift mutation impact the function of a protein?
A frameshift mutation can change the reading frame of a gene, causing a shift in the way the genetic code is read. This can lead to a different sequence of amino acids being produced, which can alter the structure and function of the protein. This can result in a non-functional or dysfunctional protein being produced.
What small-scale mutation would be most likely to have a catastrophic effect on the functioning of a protein?
A single-nucleotide substitution causing a missense mutation that changes a critical amino acid in the protein's active site or functional domain is most likely to have a catastrophic effect on the protein's function. This type of mutation can disrupt the protein's structure or its ability to interact with other molecules, leading to severe functional impairment.
How might protein synthesis execute differently if a mutation occurs?
A mutation can alter the sequence of DNA, causing changes in the mRNA produced during transcription. This can result in the insertion, deletion, or substitution of amino acids in the protein sequence during translation. These changes can impact the structure and function of the protein, potentially leading to a non-functional or altered protein being produced.
