A mutation in a gene can change the amino acid sequence of the protein the gene makes. These alterations in the proteins' primary structure may affect the secondary, tertiary, and quaternary structure, all which have to be exact for proper functioning.
The mutation in a gene can also put a STOP message in the sequence so the protein is terminated prematurely, leading to a truncated polypeptide. Some polypeptides simply won't work, and when critical proteins are not functioning, the cell can cease to run metabolic reactions or undergo mitosis. Other polypeptides will become deleterious and directly harm the cell.
Mutations in DNA affect the function of genes in various ways. The proteins which are found in the genes may be prevented from the normal functioning and this may also alter the type of proteins formed among others.
DNA codes for the sequence of amino acids in proteins. If there is a mutation in DNA, it can lead to a DNA sequence coding for the wrong amino acid. When the wrong amino acid goes into a protein, it changes the chain, causing it to function differently or to not function at all.
Cells make mistakes in copying their own DNA, inserting an incorrect base or even skipping a base as the new strand is put together.
When the mutation grows inside of you so does the cell. It becomes bigger and bigger every time the mutation grows i think

DNA can result in dysfunctional protein production?
Yes, errors in DNA can lead to mutations that disrupt the proper sequence of amino acids in a protein, causing it to be dysfunctional. This can affect the protein's structure or function, impacting various cellular processes and potentially leading to health issues.
What happens a DNA nucleotide that contains guanine is accidentally substituted for a DNA nucleotide that contains thymine?
This substitution would result in a mismatched base pair, with guanine pairing with thymine instead of cytosine. During DNA replication, this can lead to a mutation in the DNA sequence if not corrected by the DNA repair mechanisms. The mutation can potentially affect the functioning of the gene where it occurs.
What is most likely affected by a mutation in the DNA binding domain of a steroid hormone receptor?
The choices for this question were as follows:Conformational change of the receptorBinding of the hormone to the receptorTranslocation of the receptor to the nucleusCellular response to the hormoneThe answer is option 4.
What is random errors when DNA is copied called?
It's called a 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.
What is a harmful mutation?
A harmful mutation is a change in the DNA sequence that negatively impacts the functioning of an organism. This type of mutation can lead to diseases, disorders, or other health problems in individuals. Harmful mutations can disrupt normal biological processes and increase susceptibility to various conditions.
DNA can result in dysfunctional protein production?
Yes, errors in DNA can lead to mutations that disrupt the proper sequence of amino acids in a protein, causing it to be dysfunctional. This can affect the protein's structure or function, impacting various cellular processes and potentially leading to health issues.
What are some general effects of a mutation?
Some general effects of a mutation are changes in DNA/RNA sequences and plausibly alteration of the product of a gene or the prevention of a gene from functioning properly.
What happens a DNA nucleotide that contains guanine is accidentally substituted for a DNA nucleotide that contains thymine?
This substitution would result in a mismatched base pair, with guanine pairing with thymine instead of cytosine. During DNA replication, this can lead to a mutation in the DNA sequence if not corrected by the DNA repair mechanisms. The mutation can potentially affect the functioning of the gene where it occurs.

DNA insertion mutations may be caused by the invasion of?
foreign DNA into the genome, such as from viruses or transposons. These foreign DNA elements can disrupt the normal DNA sequence and result in an insertion mutation. Additionally, errors during DNA replication or repair processes can also lead to DNA insertions.
What is it in X-rays that causes damage?
The actual X-ray is what is harmful. This is a high energy wave that can disrupt DNA within cells causing cell damage, mutation or death.
What type of mutation is this during DNA replication a thymine base is removed from the DNA?
A frameshift mutation
What is random errors when DNA is copied called?
It's called a 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 mutation is a change in DNA sequence and what?
A mutation is a change in the DNA sequence that can lead to alterations in the protein produced or affect the functioning of the gene. Mutations can arise spontaneously or be induced by external factors like radiation or chemicals. Some mutations can be harmful, while others may have no effect or even be beneficial.
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.
