Genetic Engineering

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.

what part of the cell contains genetic material or genes that determine traits

If a population dwindles, there is low genetic variation and a species may risk extinction.

technology

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.

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

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.

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]

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.

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.

i want to know the answers related to dis question..

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).

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.

direct selection possible

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.

Bacterial genomes are relatively small and some (eg. E. coli) are very well characterised. Also, most bacteria have a very short generation time so any DNA that is inserted can be multiplied quickly.

Ribosomes are the organelles that read coded genetic messages. Ribosomes can be found in all living cells.

In meiosis I, segregation of chromosomes...that is, separating off into pairs, allows for crossing over to occur. Crossing over is one mechanism responsible for gene recombination to occur, and genetic recombination is one way that variations in traits increase.

5' end (nucleotides are added from 3' toward 5')

The premise of the question is flawed. Unless they are identical twins, siblings DO NOT receive the same genetic material from their parents. Normally, children receive 50% of the genes of each parent to create a new 100% combination. So you and your sibling have both inherited 50% of your father's DNA, for example, but you didn't get the same identical 50% as your sibling unless you're identical twins.

Natural hair loss is known as androgenetic alopecia and, according to the American Academy of Dermatology, is the most common cause of baldness. The gene can be inherited from either your mother's or father's side of the family, though you're more likely to have it if both of your parents had hair loss. There are also good hair supplements out there like Reloxe that could help people with hair loss problem. You can learn more of it here: http://www.reloxe.com
