The reason for conducting thorough research on mitochondrial DNA currently is to understand certain hereditary diseases that are transmitted exclusively from the mother to the offspring.

Mitochondrial DNA is unique because it is only inherited from the mother. This means that any genetic mutations or diseases carried in the mitochondrial DNA will be passed down exclusively from the mother to her children. By conducting thorough research on mitochondrial DNA, scientists can gain a deeper understanding of these hereditary diseases and how they are transmitted.

Option 1 is the correct answer because it correctly identifies the importance of studying mitochondrial DNA in order to understand diseases that are inherited exclusively from the mother`s side. This research can provide valuable insights into the causes and potential treatments for these diseases.

Options 2, 3, and 4 are incorrect. Option 2 incorrectly mentions respiratory diseases without specifying the exclusive maternal transmission. Option 3 suggests studying diseases caused by lifestyle, which is not directly related to mitochondrial DNA. Option 4 mentions diseases inherited exclusively from the paternal side, which is incorrect since mitochondrial DNA is not inherited from the father.

Alert - correct answer should be None.
