MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When are the chances of mutation increased?
A
When we are exposed to carcinogens and certain types of radiation
B
When you are exposed to radiation
C
I dont know
Explanation: 

Detailed explanation-1: -Ionizing radiation damages the genetic material in reproductive cells and results in mutations that are transmitted from generation to generation.

Detailed explanation-2: -Exposure to carcinogens can either directly [7] or indirectly [1, 8] induce DNA damage. Subsequent repair mechanisms may result in alterations in DNA sequences, i.e. mutations [2, 9]. Induced mutations may be initiating events in cancer causation, when the damage is fixed within oncogenes or tumour suppressor genes [10].

Detailed explanation-3: -When ionising radiation acts upon gonads or germ cells, it may cause damage to the genetic material (mutations) which can lead to genetically induced diseases (hereditary defects).
