Contribution of genetic factors to dental caries risk

Dental practioners found that there is a contribution of genetic factors to dental caries risk. They would find value in understanding the genetic contribution to caries risk for at least 2 reasons. First, they would be able to explain to patients that some forms of decay are more strongly associated with inherited risk. This would help explain for both the patient and dentist why persons with similar behavioral risks (ex- tooth brushing frequency or dietary habits) have different caries rates. Dental caries is a multi factorial infectious disease, with many contributory environmental factors, there is also strong evidence for a genetic component in the etiology of this disease. With information from human genome and other related technologies like microbial genomics wi...

Genetic Variation Essay Sample

Genetic Variation Essay Sample Genetic variation has many important parts to it, a big portion being mutation. A mutation is a change in the nucleotide sequence of DNA dealing with its genes and alleles. A point mutation is a change in a single base in a nucleotide sequence.

Substitution is the replacement of one nucleotide and its partner with another pair of nucleotides. A frame shift mutation occurs whenever the number of nucleotides inserted or deleted is not a multiple of three. While dealing with mutations, several characteristics must also be included. These are randomness, non-

I will explore this by using economic, entrepreneurial, as well as a recent Wall Street Journal article entitle, ‘Can Entrepreneurship be taught?’ “It is well established that, while only a small proportion of all entrepreneurial firms grow rapidly, this small minority delivers a disproportional economic impact relative to their numbers.

A Genetic Disorder: Tay-Sachs Disease Essay Sample

A Genetic Disorder: Tay-Sachs Disease Essay Sample             Most infants born with normally developed motor functions have the ability to synthesize specific enzymes necessary for a healthy growth process. But babies inflicted with a rare genetic disorder called Tay-Sachs disease experience motor dysfunction due to the continuous degradation of their central nervous system. This disorder is detectable prior a child’s birth, and it is possible to compute for the probability of a newborn phenotypically manifesting the disease.

Drug Addiction: Are Genes to Blame? Drug addiction is a widely misunderstood condition. The timeless nature versus nurture debate is often brought up when discussing drug dependence.
