Identify Application of biology in genetic engineering?
Genetic engineering is the artificial transplantation of Heriditary material[genes] of an organism. Genetic engineering is one of the most important field of biology.It has produced such varieties of plants and animals which can fulfill the requirements of food for 1 arge population. Genetic engineering is very important in the diagnosing of heriditary diseases e.g=Haemophilia, colour blindness e.t.c
What is ment by genetic mutation?
A mutation is any change to a strand of DNA which is passed on to an organism's offspring.
DNA mutations are caused usually by chemical interactions or radiation (natural and manmade), and most are harmless.
The only ones which cause serious defects (that I know of) are changes to sperm or egg cells, stem cells (which might ultimately be responsible for the DNA and development of an entire region of your anatomy) and changes which cause cancer.
If a fetus or embryo is exposed to intense radiation, they will be at high-risk for harmful genetic mutations because their body is still developing, whereas an adult will be relatively immune since most of the time if a strand of DNA in a cell is damaged the cell just dies and is replaced.
What would happen if crossing over didn't happen during meiosis in humans?
There would be less genetic variation in humans
Why genetic engineering superior to selective breeding?
Genetic modification (GM) is designed to produce desired characteristics in a plant or animal by splicing a gene that has the desired characteristic directly into the genetic code of that plant or animal. It is much faster than selective breeding
What are the disadvantages of Southern blotting?
it is a labours process
it is timeconsuming process
it required more amount of dna require 3microliter dna per sampel
it is costly
Disadvantages of genetic testing?
1- Even if an abnormal gene is present, there is no proven way to eliminate cancer risk.2- You may test positive for a gene that indicates a genetic disorder but never develop it.
3- You will face emotional distress once you find out the results. This can also affect your family and friends emotionally.
4- Negative test results may provide a false sense of security, because you may think you have no chance of getting breast cancer, which is not true.
How does meiosis create genetic diversity?
Disregarding coding errors and mutations etc.
You start with 46 chromosomes - half go to each gamete. Each one has a choice. So you have 2 to the 23 power possibilities.
that is more than 8,000,000 ... all different.
How does crossing over explain genetic variability?
Normally the genes on a chromosome are inherited as a complete set. If you get that chromosome you get all the genes on it. In the process of crossing over similar sections of DNA are swapped from one chromosome to another. This means that different pairings of genes will be inherited together going forward.
In the Indirect ELISA ,
What leads to genetic variation in a population?
Random mutations in an organism's DNA after reproduction.what lead to variations
Is sociopath a genetic behavior?
Yes, that's part of it. But there are other factors. Some of these are not yet known, but it is known that starting in infancy, some babies begin to develop neurologically in a very abnormal manner. First off, whereas most people have specific areas in one or the other hemisphere of the brain that handle various tasks, the sociopath has them scattered randomly in both hemispheres, so that memory and information are broken into small pieces; this is why their speech is often wildly contradictory. And even worse, the areas of the cerebral cortex that normally handle emotional information do not work at all, for reasons unknown, so they never develop at all, remaining as they were in infancy. Other areas process this information but in such a different way that it is incomprehensible to people who are not sociopaths, and vice-versa. The actual structure of the brain can be lopsided. Overall, it is believed that the condition is congenital but that extremely intensive therapy of an entirely different sort than usual and starting in childhood can at least keep the sociopath from causing massive damage to other people, and possibly even alleviate some of his/her own misery.
What causes a genetic disorder?
the genes are passed from both mother and father to the fetus, this is the cause of some genetic disorders, nothing can be done about this because all genes are hereditary, good along with the bad.
Is huntingtons a chromosomal or a genetic disease?
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington'
It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
What are five types of genetic engineering?
The three types of genetic engineering are:
Do you think the cloning of humans should be legal?
Cloning of animals is legal, but cloning of humans is considered to be a taboo and is not legal.
What are some advantages and disadvantages of mining engineering?
disadvantages of mining is that the chemicals used to extract the minerals will go down lakes which well put a big impact on the environment
UPDATE
This answer needs a slight correction. Chemicals are NOT used to extract minerals during mining in the United States. In some instances in South America, chemicals are used to "cluster" ores together, but this practice is not used in the United States. "Pollution of streams" that occurs in the United States is usually from the natural acidity of the geologic formations. Mining companies in the United States are required by federal law to take steps to decrease the drainage of acidic strata, so water pollution is not as prevalent as believed.
How do you get rid of love handles if you are doing your ab workouts religiously?
How does genetic engineering affect a cell's characteristics?
Allows scientists to induce a cell to make needed chemicals.
What are the disadvantages of the ELISA test?
two advantages are you don't need to use radioactive substances and it five accurate results
highly sensitive and specific
not needing radioisotopes (radioactive substances) or a costly radiation counter (a radiation-counting apparatus)
What is the scientific name for a human cell?
The scienific name for cheek is Prezwaregalopigas or Stratified (stacked) Squamous (flat) Epithelium (external covering cells)
Does sperm transport genetic material?
Sperm contributes one half of the genetic material,the egg supplies the other half.This is the main reason why sexual reproduction is used by most organisms. It creates diversity in species that make it more resilient to changing conditions.
What is jellyfish genes used for?
Jellyfish genes are used within genetically engineering certain foods. The jellyfish genes are added to wheat to make the wheat glow when it needs water.
A bacterium has one that holds its genetic material?
yes. it has only one chromosome that holds its genetic material, however they may also have plasmids that contain genetic material
What are the sources of genetic variation?
Mutation is the ultimate source of all genetic diversity. Viruses that infect bacteria are bacteriophages. A mutation within a gene that will insert a premature stop codon in mRNA would result in a shortened polypeptide chain.
