What are the severe complication associated with DNA damage?

DNA is a molecule which carry genetic informations  in living organisms. DNA molecule contains such instruction which are require for an organism to reproduce and survival of organism. DNA also controls all the traits which we inherit from our parents. DNA is hereditary material because it store all the information and pass this information from one generation to other generation. DNA as hereditary material transfer genetic information.



Life without DNA:


Concept of life without a DNA is nothing because without DNA , living organism can not grow.


A cell without DNA do not have any capacity to do any kind of function because DNA gives instruction to genes to make proteins . DNA is used to identify pathogens, identifying human migration patterns, tracing the diseases.



DNA damage:


DNA damage is the changes which occur in DNA and  cause cellular injuries  in body and stop reproduction.This is a very severe phenomena .DNA damage effects the normal functioning of replicative cells and also effects the rate of apoptosis. DNA damage and mutation are connected to each other. The DNA damage caused by ultraviolet radiation is very common. 


DNA damage leads to accumulation of adult stem cells in body.DNA damage within a cell is called metastasis. DNA damage associated with X-rays is very common.






DNA damage causes:


  • Mutagenic chemicals
  • High energy radiations
  • DNA damage from UV radiation
  • Chemotherapy
  • Exposure to genotoxic agents


DNA damage symptoms:


  • High blood pressure
  • Color changes like grey hair
  • Wrinkles on body
  • Getting older very fast


Diseases which are associated with DNA damage:


  • Xeroderma pigmentosum
  • Ataxia telangiectasia
  • Bloom’s and Werner’s syndrome
  • Hereditary non polyposis colon cancer
  • Li-Fraumeni syndrome
  • breast cancer


These are some disorders which are associated with the DNA damage.


Our DNA is the main molecule for our traits and if DNA is damage then our whole system of body is completely disturbs because life does not exist without DNA.

  An infective agent that typically consist of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host. u   Latin word u   Meaning poison u   Smaller than bacteria u   Smaller than the smallest cell Can you find the size of viruses? u   The name virus was given by Beijernick in 1898 u   He studied filtered  plant juices and    found that  they caused  healthy plants to    become sick . 1.       Viruses have non- living structures 2.       Non cellular structure 3.       Contain a protein coat called the capsid 4.       Viruses have nucleic acid core containing DNA or RNA 5.       Capable of reproducing only when inside a host cell 6.       Most viruses infect only specific host...

  Green tea has been credited for centuries with significant medicinal properties. Recent studies have confirmed its many benefits, and have attested to the importance of this ancient plant in the longevity of those who drink it often.   Originally from China, where it has been consumed for millennia, green tea did not make its way to the  rest of the world until just a few centuries ago. Unlike other teas, and as a result of being air -dried  without fermentation, it retains its active elements even after being dried and crumbled. It offers meaningful health benefits such as     Controlling cholesterol Lowering blood sugar levels Improving circulation  Protection against the flu Promoting bone health Protection against certain bacterial infectious Protection against UV damage Cleansing and diuretic effects          White tea, with its high concentration of polyphenols, may be even more effective ag...
