There are certain genetic conditions that predispose a person to high cholesterol notably the group of conditions known as hyperlipidemias. However, eating a healthy diet low in cholesterol and saturated fat and exercising regularly can dramatically improve cholesterol and overall health in nearly all people.

Some woman have a hairy chest. Amounts of hair vary based on genes, removal methods used, and amount of testosterone in their body.
How have scientists used genetic engineering to change horses?
So far all i know is that they use high maitanace machines with studs to increase stamina over extremely long periods of time, like 14 hours a day, 6 days a week, people are arguing that it is animal abuse.
Is Peyronie's disease possibly genetic?
Because of the statistical link that suggests men from the norther Europe (Scandinavian countries and the U.K.) are more inclined to develop Peyronie's disease than those from Asia, Africa or other parts of the world, the genetic factor is difficult to refute. However, men whose ancestors do not hail from northern Europe do develop Peyronie's disease when physical trauma or drug toxicity are significant.
How do genetically engineered drugs help people with hemophilia?
The production of clotting factor proteins (the treatment for hemophilia) has many different parts. While much of the clotting factor protein used to treat hemophilia is recombinant (I'll explain this term in the next paragraph) I feel it important to also point out that a lot of the medications are still plasma derived, basically just separated off from human blood.
The recombinant protein molecules that are used to treat hemophilia (for the sake of the question we'll use the term drug, even though it would more accurately be called a biologic) are created in a lab, not being pulled out of human blood. The molecules themselves are not exactly being genetically engineered either. To produce these protein molecules, specific cells have been genetically engineered to create them and excrete them as a biproduct. These cells are cultured in large vats where the protein molecules are collected.
Advantages to these "recombinant" medications are in the purity and perceived safety. Since the protein molecules are not derived from blood the chance of contamination from a contaminated blood supply can be eliminated. The ability to culture these cells and produce the proteins in this manner also prevent the supply of the medication from relying on the blood supply, which throughout recent history has varied greatly as natural catastrophes, wars, and many other situations may deplete the blood supply.
When I was pregnant I had a period the first month and it was different from all other periods I had previously had, It wasn't as heavy and didn't last as long. However my urine test was positive but I have heard of other friends who had negative results and were in fact pregnant. So I would suggest going to your obgyn for more answers
harshey and chase Martha had given the revolutionary concept dat DNA is d means by wich genetical informations r being transfered from one generation to anothr...by there observation based on VIRUS radioactivational experiment.....
Which is the best university in UK for msc in genetics?
Hard to say unless you've studied at all of them ;)
Oxford / Cambridge is going to be good, but Cardiff is also particularly good.
Is iddm is genetic or niddmis genetic disorder?
IDDM is still idiopathic although the the most likely cause of Type I diabetes is immune sequel. Antibodies that were activated against a viral infection are also capable of crossreacting with similar antigens presented on human cells. These can be autoantibodies for insulin, islet cells of the pancreas or to glutamic acid decarboxylase.
Insulin autoantibodies are predominantly found in younger children (<5 yrs) and is known as micro insulin autoantibodies( MIAA)
For islet cell autoantibodies there are two beta islet cells that show specificity to Type 1 DM. Autoantibodies to IA2 are found in a majority of Type I diabetic patients. IAR (also known as "phogrin") is also a marker on the beta islet cells.
What causes genetic mutations?
Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is an expample of a chemical mutagen
In an individual has no genetic code for phenylalanine?
An individual who cannot produce phenylalanine would not be viable so I believe what you are asking about is Phenylketonuria which is a genetic disorder found is infants who cannot properly digest phenylalanine (they can manufacture it).
Hospitals test for this disorder in newborns because it is imperative to place babies that test positive on a strict diet to prevent the mental retardation that is associated with the disorder. Early intervention results in a nearly normal life.
Is it true that DNA technology used in the Human Genome Project can show whether people are related?
Yes it will reveal the relationship among individuals in the days to come.
One leg has excessive hair growth why?
If one leg has excessive hair growth it could be because of the side a person sleeps on. Hair will grow faster on the body on areas that a person does not sleep on. If a person sleeps on the left side, for example, the left side might have less body hair.
What are the advantages and disadvantages of B.T. Cotton?
- The level of toxin expression can be very high thus delivering sufficient dosage to the pest.
- The toxin expression is contained within the plant system and hence only those insects that feed on the crop perish.
- The toxin expression can be modulated by using tissue-specific promoters, and replaces the use of synthetic pesticides in the environment. The latter observation has been well documented world-wide.
There was also a report in Nature, that Bt maize was contaminating maize in its center of origin.[26] Naturelater "concluded that the evidence available is not sufficient to justify the publication of the original paper."[27] A subsequent large-scale study failed to find any evidence of contamination in Oaxaca.[28]
There is also a hypothetical risk that for example, transgenic maize will crossbreed with wild grass variants, and that the Bt-gene will end up in a natural environment, retaining its toxicity. An event like this would have ecological implications, as well as increasing the risk of Bt resistance arising in the general herbivore population. However, there is no evidence of crossbreeding between maize and wild grasses.
As of 2007, a new phenomenon called Colony Collapse Disorder (CCD) is affecting bee hives all over North America. Initial speculation on possible causes ranged from cell phone and pesticide use[29] to the use of Bt resistant transgenic crops.[30] The Mid-Atlantic Apiculture Research and Extension Consortium published a report on 2007-03-27 that found no evidence that pollen from Bt crops is adversely affecting bees. CCD has since been attributed to a new virus, unrelated to Bt crops.[31]
What are two main ways in which human genetics follows the genetic patterns seen in other organism?
First, meiosis independently assorts chromosomes when gametes are made for sexual reproduction and second, human heredity involves the same relationsips between alleles-dominant and recessive interactions, polygenic traits, and sex-linked genes.
Plants are expected to be genetically engineered to have?
resistance to the elements (such as cold and hail) and pests. Also they're engineered to have a larger crop
Is addison's disease a genetic?
NO, it is not genetic, Although the disease is hell and if you have it, like I do, I feel very sorry for you and please take care of yourself and be sure to carry information on your disease because it is rare that Emergency rooms know anything about this rare disease.
Discuss the issues related to genetic mutations: sexual reproductions, migration and population size
Serum is generally free from blood cellular components but when collecting serum sometimes few cells will be pipetted with the serum & that is the only source of DNA in the serum.
Founder effect refers to the loss of genetic variation when a new colony is established by a very small number of individuals from a larger population. As a result of the loss of genetic variation, the new population may be distinctively different.
Bottleneck effect is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude.
Population bottlenecks increase genetic drift, as the rate of drift is inversely proportional to the population size.
They also increase inbreeding due to the reduced pool of possible mates.
