| In the study
of DNA, medical science is making new discoveries and advancements.
The human body is made to withstand a series of overlapping mechanisms
to cope with the after-effects of detrimental environmental exposure.
According to scientists, these molecular pathways are managed
by genetics. As a result, genes may consist of thousands of diminutive
variations with either more or less enzyme or protein production.
These disparities contribute to the human body’s diversity and
define the various susceptibilities of chronic diseases.
For instance, one researcher has found a potential
hereditary component to nicotine addiction. The correlation
between genetics has been linked to the inability to quit smoking
cigarettes. The clinical trials found that certain smokers experienced
more pleasure from the inhalation of nicotine than other individuals.
The finding was traced to the brain's genetic differences along
with the way the reward pathway is mapped to release dopamine.
Current trials have theorized that the DNA
repair capacity may be regulated by the process known as genetic
control. The theory explains how certain people are more susceptible.
The process works when the genetic control helps maintain the
integrity of genes. The genes are perpetually repaired of the
damage that occurs to DNA (exposure to harsh chemicals (nicotine)
ultra-violet rays). When an error transpires during the repair
system, DNA damage may trigger unstable genes and a heightened
risk of cancer.
In conclusion, researchers have found that
certain patients have stronger DNA repair functions than other
people. With the new breakthrough in medical science, physicians
may be able to diagnose patients at an earlier age who are at
higher risk of acquiring cancer. As a result, customized medical
therapies could be prescribed to prevent individuals at the
highest risk of cancer from exposure. |
