✍️ Sample MCAT Questions & Answers

1. In Merton's strain theory, an individual who rejects both the cultural goals of society and the legitimate means to achieve them, then substitutes new goals and means, is classified as a:

✓ Rebel

Rebels reject society's goals and means and actively seek to replace them with alternative ones, as seen in revolutionary social movements.

2. Which step of fatty acid synthesis requires the direct input of CO₂ (as bicarbonate)?

✓ Carboxylation of acetyl-CoA to malonyl-CoA

Acetyl-CoA carboxylase adds CO₂ to acetyl-CoA to form malonyl-CoA, the activated two-carbon donor for fatty acid chain elongation.

3. Which memory category would explicit memory fall into?

✓ long-term memory

Explicit memory, also known as declarative memory, refers to memories that are consciously recalled, such as facts, events, and concepts. This type of memory is a component of long-term memory, which has a vast capacity and can store information for extended periods, ranging from minutes to a lifetime.

4. Which protein secondary structure is stabilized by hydrogen bonds between residues distant in primary sequence?

✓ Beta sheet

Beta sheets form hydrogen bonds between backbone atoms of strands that are far apart in the primary sequence, while alpha helices bond residues close together (i and i+4).

5. Which scientific method step follows hypothesis formation?

✓ Experimentation and testing

After forming a hypothesis, the next step is designing and conducting experiments to test whether the hypothesis is supported by evidence.

6. During eukaryotic RNA processing, which modification is added to the 5' end of pre-mRNA?

✓ A 7-methylguanosine (m7G) cap

A 7-methylguanosine cap is co-transcriptionally added to the 5' end of pre-mRNA, protecting it from exonucleolytic degradation and facilitating ribosome recognition for translation initiation.
