How does genetic mutation occur?
Gene mutations may occur in at least three Ways: they can be inherited from a parent, or acquired during a person's lifetime - See Epigenetics - or acquired during a person's lifetime - see Strontium 90.
What is time complexity of genetic algorithm?
The answer to this question depends on several things, the most important of which is the fitness evaluation. I'm going to ignore evaluation- you must determine this for yourself based on your application. Some of the things the effect the time complexity are:the data structures used to represent the individuals and the population, the genetic operators used, and the implementation of the genetic operators. Roulette wheel selection, for example, can be anywhere from O(n^2) when done naively, to O(log(n)), or even O(n) using something like Vose Alias Algorithm. The simplest case- roulette wheel selection, point mutation, and one point crossover with both individuals and populations represented by fixed length vectors- has time complexity O(gens * (mut + cross + select)) where gens is the number of generations, mut is the complexity of point mutation (n*m with n the size of the population and m the size of the individuals), cross the time complexity of crossover (n*m again), and select the time complexity of selection (n in the case of an efficiently done roulette wheel). Therefore, the time complexity of a simple Genetic Algorithm is O(gens*n*m) as this is the dominating term. I'm sure a much better explanation can be found in the literature.
Do you Think there should be any limitations on genetics engineering Give reason to support your position?
Yes!! Genetic engineering is defined as the direct manipulation of an organism's genes. Though I do believe there should be some limitations on what we do with genetic engineering, it can cure so many genetic disorders and illnesses. Keep in mind that nearly EVERY human disorder has an underlying genetic cause. For instance, people with Sick Cell Anemia have a point mutation in the gene that codes for hemoglobin. This mutation results in abnormal function of the hemoglobin in their blood cells, which causes the cells to turn sickle shaped when they are deoxygenated. It shortens life expectancy to mid 40s, and can cause very painful and potentially lethal complications. However, with genetic engineering we could insert a functioning copy of the gene into a patient's bone marrow cells, and they would be able to produce normal blood cells. In a few months after all their defective sickle blood cells died off, they would be free of the disease. However, I think use of genetic engineering to change a human's appearance, intelligence, or behavior is too much.
What evidence support the concept of the universal genetic code?
AnswerThe universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. From a religious point of view, it could also be said that the creator god designed a successful genetic code and chose to use it universally. So, the genetic code does not actually prove or disprove evolution versus religion. But it proves the Theory of Evolution to be the best scientific explanation ofr life on earth.
The projection of a point onto a line is a?
Point.
How can a point mutation alter the final structure of a protein?
In a point mutation, one nitrogen base is substituted for the correct base. Since most amino acids can be coded for by more than one codon, there may be no consequence to this mutation. However, sometimes a point mutation results in an incorrect amino acid being added to the amino acid sequence of the protein. This can cause a change in the shape and therefore function of the protein, which can be a harmful mutation. Two genetic disorders caused by a point mutation are cystic fibrosis and sickle cell anemia.
Define a genetic mutation and state the types of genetic mutations?
Point mutation: single nucleotide is replaced with another. ex: sickle cell anemia.
How point mutation frame shift mutation and meiosis contribute to genetic variation?
Nicely. Do your project on your own!
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.
Is Huntington's Disease a gene mutation?
No, it's caused by a single point mutation of a gene.
What diseases are thought to be caused by point mutation?
Sickle cell anemia.
The substitution of one base for another during DNA replication is an example of?
Mutation occurs where one DNA nucleotide base is changed in the process of DNA replication. These mutations may or may not cause genetic disorders or other observable changes in the organism, but they play a huge role in evolution, cancer, and immune system development.
What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.
What result when a misreading occurs in the copying of DNA?
A mutation, usually a point mutation (where a single 'letter' in the genetic code is changed).
What would happen if UV exposure caused a point mutation where a single base was changed within your DNA sequence?
It would depend upon type and location of point mutation .
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
A change in a single nucleotide in DNA-?
A mutation
