🎯 Exam Strategy

Guaranteed Marks Plan

How to approach each part of the ICB exam for maximum marks.

Part A
25 MCQs × 1 = 25 marks
Target: 20–23 / 25
  • Central Dogma of Molecular Biology 8/8
  • BLAST vs FASTA — differences & use cases 8/8
  • Needleman-Wunsch vs Smith-Waterman 8/8
  • DNA structure — bases, bonds, anti-parallel 7/8
  • GenBank / UniProt / PDB — which database stores what 7/8
  • PAM vs BLOSUM substitution matrices 7/8
  • PCR steps & applications 6/8
  • UPGMA vs NJ — phylogenetic tree construction 6/8
  • Open Reading Frame (ORF) definition & finding 6/8
  • Homology, Analogy, Ortholog, Paralog definitions 5/8
Part B
5 Questions × 8 = 40 marks
Target: 32–40 / 40
QUnitExpected Topic
21U1Central Dogma + DNA replication steps with diagram
22U2Perform Needleman-Wunsch alignment with full scoring matrix 🔥
23U2/U3BLAST algorithm explanation OR database searching strategy 🔥
24U3/U4Genomics + phylogenetic tree construction (UPGMA)
25U4/U5Phylogenetics OR Protein Structure OR Drug Discovery pipeline
Part C
1 Question × 10 = 10 marks
Target: 8–10 / 10

Choose 1 of 2 questions. Typical options:

Q.26
Smith-Waterman local alignment — full DP matrix + traceback 🔥 OR Complete genomics pipeline from sequencing to annotation
Q.27
Phylogenetic tree from distance matrix using UPGMA — show all steps OR Structural bioinformatics — protein secondary/tertiary structure & prediction methods
💡 ICB Exam Secret: Always show your SCORING MATRIX table for alignment questions. Even partial/wrong final alignment earns marks for a correct DP table. Draw each cell fill-in step clearly.
