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 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.
What factor causes the greatest change in gene pools?
Environmental factors cause the greatest change in gene pools. some of these factors are radiation,pollution,food supply,population,predators,and camouflage. Of these factors the most important to today's gene pool is radiation because it causes mutation in the chromosomes and can completely change an organism.
Does gene mutation affect metabolism?
yes and no,some mutations are only inward and affect inward organisms. Some are only outward like apperacance.
What is the difference between gene and chromosomal mutation?
A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome. A chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement The differences between Gene mutation and Chromosome mutation are ; 1- Chromosome mutations involve changes in the structure of a chromosome OR the loss or gain of a chromosome while Gene mutations involve a change in the nucleotide -base sequence of a gene on a DNA molecule. 2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome while a chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement 4-gene mutation is just a substitute in any old random nucleotide for any old random nucleotide chromosome mutation is missing of chromosome or +1 chromosome (down's syndrome).
Can a mutation of one nucleotide on a gene be fatal to the individual that carries it?
in some cases it could be. depends on the mutation and the gene.
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.
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.
Name 2 major types of mutation?
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......

What are the factors that cause evolution to occur?
The two main factors are mutation and natural selection.Mutations are random changes in our DNA that cause changes. Some of these changes are bad, some are neutral, and some are good.This is where natural selection comes in. If the mutation is bad, then that organism is less likely to mate and pass down the gene. The organism dies along with the mutation that made it less fit. If it is neutral, which is what most mutations are, then nothing happens. If it is good, then the organism is more likely to survive and pass down the gene which will then propagate through the species.
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
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).
What is a X linked carrier homozygous?
An X linked carrier is one who carries a mutation in a gene found on the X sex chromosome. A carrier of the trait doesn't display phenotypic symptoms of the disease or mutation but can transfer the mutation in that gene to their offspring (ex: the carrier of a premutation that when transferred to the offspring via the X chromosome will cause the full mutation associated with that gene). A person could be a homozygous carrier if for instance, she were female (two X chromosomes) and carried the premutation associated with the disease. Some diseases need both alleles of the gene to be mutated. If only one allele is mutated (heterozygote) that person may be a carrier for that mutation and can thus pass on that mutation to their children.
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.
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.
Why do gingers exist?
you were born that way ....and the mutation of a gene that makes like 10 % of the population to be that way. It's a recessive gene, so in some hundreds of years it is possible to have a "ginger extinction".
