Real stories from students who achieved their NEET dreams with us
"Molecular biology including DNA replication, transcription, and translation was taught with step-by-step animations. I could visualise every molecular process."
Vaibhav Soni
AIR 234 | AIIMS Delhi
"The molecular biology tuition explained lac operon, genetic code properties, and central dogma with such clarity that these became my highest-scoring topics."
Garima Tiwari
AIR 456 | BHU Varanasi
"I feared molecular biology before Cerebrum. After the tuition, DNA fingerprinting and recombinant DNA technology became topics I actually enjoyed solving."

Molecular Biology revolves around the central dogma of molecular biology: DNA replication, transcription of DNA to mRNA, and translation of mRNA to protein. NEET tests each process in detail, expecting students to know the specific enzymes involved, the directionality of synthesis, and the differences between prokaryotic and eukaryotic mechanisms. DNA replication questions focus on the roles of helicase, primase, DNA polymerase III, and ligase, along with the distinction between the leading strand (continuous synthesis) and lagging strand (Okazaki fragments). Transcription questions test knowledge of RNA polymerase binding to the promoter, the template versus coding strand distinction, and post-transcriptional modifications like 5-prime capping and 3-prime polyadenylation in eukaryotes. A thorough understanding of these processes is non-negotiable for scoring well in this high-weightage chapter.
The genetic code section tests properties such as degeneracy (multiple codons for one amino acid), universality (same code across organisms with rare exceptions), and non-overlapping nature. NEET questions may present an mRNA sequence and ask for the amino acid sequence, or ask about wobble pairing and its significance. The lac operon model of gene regulation is another NEET favourite, with questions testing the roles of the structural genes (lacZ, lacY, lacA), the regulatory gene producing the repressor protein, the operator sequence, and the role of lactose as an inducer. Students must understand both the repressed state (no lactose, repressor bound to operator) and the induced state (lactose present, repressor released). Diagram-based questions showing the operon structure with different components labelled are particularly common and require clear visual understanding.
NEET frequently asks about specific enzymes like helicase, topoisomerase, and ligase.
Diagram-based operon questions appear in most NEET papers.
Translation of mRNA to amino acid sequence is a commonly tested skill.
Differences in RNA polymerase types and post-transcriptional modifications are frequently tested.
