Should you continue to use genetic engineering?
no you may not even get the results you asked for. the cost is tremendous anyway, the cost may even be the child's life why risk that. take the chance of having a child naturally and save the risks and chances later.
Are farm crops getting more resistant to insects disease and other pests?
Yes and no. More resistance is being both bred and engineered into crops all the time. However, the germplasm pool for the major crop classes such as corn, soybeans and wheat is shrinking all the time which leaves the worldwide supplies at more risk should a disease or insect adapt to existing varieties. This is why plant breeders are frequently trying to find new "landraces" (old original plant forms) of crops to breed into existing germplasm to create more varied resistance.
No list cannot answer but Gregor Mendel is a possible answer. There are many people in the history of genetics
Do Hershey products contain genetic engineering?
Due to pressure from some anti-GMO groups Hersheys has begun transitioning the ingredients in its products to use less and less GMO and hormone augmented products such as getting away from using milk from cows that have been treated with growth hormones to stimulate milk production and switching from high-fructose corn syrup back to simple sucrose sugars. The biggest push has been in products intended for the European market which has overwhelming phobias about anything that might be GMO related even when there is no evidence of harmful effects (and in a few cases actual significant evidence of significant benefits). Some of the changes will definitely result in more healthy products - others are nothing but hype.
Relate the use of genetic engineering to the treatment of human illness such as hemophilia?
Many genetically engineered proteins are used to treat illnesses. For example, factor
VIII, a protein that promotes blood clotting, is now made by genetic engineering and sold
as a drug to hemophiliacs. Genetic engineers are also attempting to replace defective
human genes with healthy ones.
What are genetic materials that cause cancer?
Abnormalities of the genetic materials are the only known cause of cancer. Errors in DNA replication and heritability of the genetic diseases are the cause of cancer during birth stage. Excessive ultraviolet radiation, any harmful infectious agents, tobacco smokes or chemicals are responsible for the abnormalities of genetic materials. Genes which promote cancer are called oncogenes. They are activated in cancer Cells. Tumor suppressive genes are not activated in the cancer Cells. For that reason programmed cell death and hyper active division and growth of Cells cannot be prevented. Inaccurate DNA replication, irregular Cell cycle, damaging the immune system are the major symptoms of cancer.
Its a pedigree. A pedigree shows the inheritance of a genetic disorder within a family and can help to determine the inheritance pattern and whether any particular individual has an allele for that disorder.
Can you identify the part of the cell that contains genetic materials that determine traits?
what part of the cell contains genetic material or genes that determine traits
Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
Is genetic variation always good?
Not all. Certain types of diseases are caused by mutations. Some may seem like bad some may seem as good ones in certain cases. Sickle Cell anemia is a common example where it would be seem as bad in urban areas but in areas with high malaria populations its a good thing.
What are 2 sources of genetic variation in a population?
Any two of:
Mutations
Non-disjunctions during anaphase of meiosis
Polyploidy
Sexual reproduction e.g. crossing-over/recombination during meiosis
IF YOU ARE LOOKING FOR THE STUDYISLAND ANSWER IT IS
a population whose members have many different traits
Should GMO food be served in the school cafeteria?
Opinions about serving food in school cafeterias will vary. Here are some opinions:
No, there are still too many uncertainties about health effects of GMO foods for them to be served to children and teens.
Is schizophrenia a genetic condition?
A combination of genetic and environmental factors play a role in the development of schizophrenia.[2][3] People with a family history of schizophrenia who suffer a transient psychosis have a 20-40% chance of being diagnosed one year later.[23]
Estimates of heritability vary because of the difficulty in separating the effects of genetics and the environment.[24] The greatest risk for developing schizophrenia is having a first-degree relative with the disease (risk is 6.5%); more than 40% of monozygotic twins of those with schizophrenia are also affected.[3] It is likely that many genes are involved, each of small effect and unknown transmission and expression.[3] Many possible candidates have been proposed, including specific copy number variations, NOTCH4, and histone protein loci.[25] A number of genome-wide associations such as zinc finger protein 804A have also been linked.[26] There appears to be significant overlap in the genetics of schizophrenia and bipolar disorder.[27]
How do scientists use genetic markers?
Genetic markers are some of the most important material in the human body. Scientists uses the markers to study a baby's chances of a certain defect. They also study them in the battle against diseases such as cancer.
What are some bad things about animal cloning?
Some bad things about animal cloning is that it messes with nature and the life cycle. It also can harm the original organism and create mutants.
What subjects should you take after 10 for becoming a genetic engineer?
i want to know the answers related to dis question..
Genetic modification is when you take a beneficial gene, a bit of DNA, from one species and add it to the DNA sequence of another species. The genetically modified subject will use the gene and benefit from it, for example to grow better fruit or be resistant to disease, or to produce insulin.
The above process has been done for thousands of years by a bacteria called Agrobacterium which causes a plant root disease called "Agrobacterium Root Gall" The disease causing genes can be replaced with other sequences of DNA which the bacteria then inserts into the plant for them. There are many different ways, but this is the most common.
Genetic manipulation is also done in medicine and agriculture. In agriculture, it is most commonly done to create crops that are resistant to synthetic herbicides or to create crops that produce a substance that kills insects when they eat the plant.
Hemophilla is genetic disorder that is?
Hemophilla is a genetic disorder in which there is absence of clotting factor viii, leading to defective clot formation, petechiae bruising and gum bleeding. Treatment is by injecting factor VIII concentrate
James Watson and Francis Crick discovered that DNA was structured as a double helix. In 1962, their discovery won them a shared Nobel Prize (with Maurice Wilkins).
What diseases can be treated with chelation therapy?
Edetate calcium disodium (EDTA calcium) and dimercaprol (BAL) are given through an intravenous line or in shots, while succimer (Chemet) and penicillamine (Cuprimine, Depen) are taken by mouth.
The use of an antibiotic resistance gene on a plasmid used in genetic engineering makes?
direct selection possible
What is the purpose of cloning plants?
Tissue culture cloning is the process of taking small parts of specimen plants and creating unlimited numbers of exact genetic copies asexually in a sterile lab setting. This process has been adapted to create genetically altered commercial food and medicinal crops.
