Gene mutations can be caused by various events, including exposure to radiation, such as ultraviolet light or X-rays, which can damage DNA. Chemical agents, known as mutagens, like those found in tobacco smoke or certain industrial chemicals, can also lead to mutations by altering the DNA structure. Additionally, errors during DNA replication or repair processes can result in spontaneous mutations. Lastly, viral infections can integrate their genetic material into a host's DNA, potentially causing mutations.

Is pku a point shirt or a frameshift mutation?
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
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.
How can mutation be formed?
A gene mutation occurs when there is a permenent change on one's DNA. They can be inherited by the parent or form in someone's life due to enviromental changes or problems. They pass on from generation to generation. Gene mutations can be good or bad.
Is cystic fibrosis a candidate good for gene therapy?
Yes, cystic fibrosis is a candidate for gene therapy. Gene therapy offers the potential to correct the underlying genetic cause of the disease, which is a mutation in the CFTR gene. While there have been some promising developments in gene therapy for cystic fibrosis, further research and clinical trials are needed to fully assess its effectiveness.
What does spontaneous gene mutation mean?
Genes are a few pieces along a chromosome. When a cell divides, the chromosome is copied. Some time the copy is not exact. Have you ever copied something and ever made a mistake? A gene might have an extra instruction added or an instruction deleted. Sometimes, a gene will be duplicated. Frequently the mistake causes the death of the cell. Sometimes it gives an organism an advantage of some type. Some people in parts of Russia can not catch AIDS due to a mutation. At one time such changes were called spontaneous. Now it is suspected such changes are caused by mistakes in copying.
Is mutation dominate or recessive?
it depends on what mutation you speak of. some are and some are not.
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 is a mutation of a single gene?
by what protocol we can mutate a single gene from leishmania BY ANOTHER PERSON - The answer is POINT mutation. I'm doing the worksheet too LOL hahah everyone is doing miggis homework huh === Too bad I can't find the rest of the answers for that homework D: But yea it is Point Some genetic disorders result when a mutation causes the product of a single gene to be altered or missing. ~From my science book o-o lol
Is infertility a gene mutation?
No infertility is not caused by a gene mutation. Infertility is the inability to conceive a child or carry a pregnancy to term. It may be caused by a variety of factors including: Damage to reproductive organs Hormonal imbalances Chromosomal abnormalities Environmental factors Lifestyle choicesIn some cases infertility may be caused by a gene mutation but this is rare. In general gene mutations are a contributing factor rather than the sole cause of infertility.
A mutation in a gene may not affect an individual's phenotype because?
the mutation may occur in a non-coding region of the gene, resulting in no change to the protein produced. Additionally, the mutation may be silent, meaning it does not alter the amino acid sequence of the protein. In some cases, the organism may have redundant genes that compensate for the mutation, allowing it to function normally.
What is the function of mutated gene?
to enable mutation in adapting the host to its changing environments, and so keep up with natuaral selection. A mutation of a gene is a gene that is expressed differently from the majority of the species. Some mutations are harmful; ie: cancer, and some are helpful whilst others are niether harmful nor beneficial (ie: the gene for ginger hair).
When one pair of bases is replaced in a gene it is called?
It is called a point mutation. Depending on where the bases are, as far as in the codon, some are not harmful.
Can a mutation of one nucleotide on a gene be fatal to the individual that carries it?
Yes, a mutation of one nucleotide on a gene can be fatal if it leads to a non-functional protein being produced, causing a critical biological process to fail. Mutations that disrupt essential cellular functions can lead to severe health problems or death.
How many copies of an allele need to be present for someone to have cystic fibrosis?
Both cystic fibrosis and sickle cell anemia are single mutation diseases - one mutation in a single gene is enough to cause the disease. However, for cystic fibrosis both alleles of the gene must be mutated for the disease to develop. For sickle cell anemia, only one allele can carry the mutation and some signs of the disorder will be present. Having two alleles with the mutation causes much more significant disease.
