Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).

Answer: ACh
Explanation:
The Acetylcholine is an organic chemical that plays a major role in the brain and other parts of the body. It functions by transmitting messages from the brain to the various parts of the body.
It also helps in retaining memory as it enhances the alertness when we wake up. This hormone also helps in the sustaining attention and learning memory.
If the neurons stops producing acetylcholine then the brain does not retains information and is associated with memory loss.
Hence, the correct answer is Option B
The primary concern of the scientist in clinical trial is patient safety.
A clinical trial is one of the final stages of any research process according to the requirement. Studies are done to find if the approach of the research and treatment is effective.
Clinical test or trial on human beings is done only after the pre-clinical phase which involves laboratory studies on animals (in vitro) to check the safety and efficiency of the drug. Animals are quite different from humans so human clinical trials are required to be done.
The main aim of clinical trial involves three major things to be considered: if the drug is working, the efficiency of the drug as compared to the currently present drug and most importantly that the drug is safe for human use and the patient is safe after the administration of the drug into the body.
