<u>Option: D</u>
<u>Explanation:</u>
A kind of design for observational study is understood as a cross-sectional framework. In a cross-sectional analysis the investigator simultaneously tests the participants in the study's result and exposures. Through cross sectional studies one can estimate the prevalence of disease.
A cross-sectional analysis, for instance, could be used to assess whether vulnerability to specific risk factors would correlate with specific outcomes. For illustration, a researcher may gather cross-sectional data about past smoking habits and current lung cancer diagnoses.
The answer is 3’-tactttaggatc-5’. This is complementary to 5'-augaaauccuag-3' of the mRNA. It is important to note that RNA has no thiamine but instead has uracil (Thymine is a methylated form of Uracil.). The other principles on bae pairing apply where C pairs with G, and U with A. Thiamine is used in DNA because it gives it more stability than uracil does.
