Junior Scientific Officer (BS-16), AFIP, Ministry of Defence (Case No. 117/2026)

FPSC Junior Scientific Officer (BS-16) - AFIP

The Armed Forces Institute of Pathology (AFIP) in Rawalpindi, functioning under the Ministry of Defence, is Pakistan’s premier tertiary-care diagnostic and medical research facility. The post of Junior Scientific Officer (BS-16) (Case No. 117/2026) recruits specialized scientific personnel across molecular diagnostics, clinical genomics, and biochemical investigation.

Official Syllabus Specification

The FPSC examination for Case No. 117/2026 consists of a single 100-mark MCQ objective screening test:

Part-I: English (20 Marks)

• Grammar Usage: Tenses, prepositions, subject-verb agreement, and articles.
• Sentence Structuring: Identifying grammatical flaws, modifying phrases, parallel structures, and academic sentence completion.

Part-II: General Science / Specialized Bioscience Test (80 Marks)

Candidates are tested on graduate (BS 4-Year / M.Sc.) curriculum:

1. Biochemistry: Amino acids, protein structure hierarchies, enzyme kinetics (Michaelis-Menten kinetics), glycolysis, Krebs cycle, oxidative phosphorylation, lipid metabolism.
2. Human Physiology: Homeostasis, blood cell lineages, renal clearance mechanisms, respiratory gas exchange, neuromuscular transmission, and cardiac cycles.
3. Immunology: Humoral vs. cell-mediated immunity, MHC class I and II complexes, antibody structures (IgG, IgM, IgA, IgE, IgD), immunological techniques (ELISA, Western Blot, RIA, Immunohistochemistry).
4. Mycology: Fungal taxonomy, medically significant fungi (Candida, Aspergillus, Cryptococcus), mycotoxins, diagnostic fungal culture media (SDA), and antifungal modes of action.
5. Biological Databases: Primary vs. secondary databases, NCBI Entrez, GenBank accession formats, UniProtKB, Protein Data Bank (PDB), EMBL-EBI.
6. Evolutionary Biology & Phylogenetics: Sequence alignment (global vs. local, Needleman-Wunsch, Smith-Waterman), scoring matrices (PAM, BLOSUM62), neighbor-joining and maximum likelihood phylogenetic tree reconstruction.
7. Genomics & Transcriptomics: Sanger sequencing principles, High-Throughput / Next-Generation Sequencing (Illumina, Nanopore), RNA isolation, cDNA synthesis, real-time quantitative PCR (RT-qPCR).
8. Structural Bioinformatics & Proteomics: Secondary structure prediction (Chou-Fasman, GOR), tertiary structure homology modeling, Ramachandran plot analysis, mass spectrometry (MALDI-TOF, LC-MS).
9. Molecular Docking & Drug Discovery: Lead compound identification, structure-based vs. ligand-based drug design, binding energy calculations, hydrogen bonding and electrostatic interactions.
10. DNA & RNA Structure: Double helix dimensions (Watson-Crick model), major and minor grooves, A, B, and Z DNA conformations, mRNA, tRNA hairpin loops, rRNA assemblies.
11. Chromosomes & Chromatin: Nucleosome core octamer (H2A, H2B, H3, H4), linker histone H1, euchromatin vs. heterochromatin, telomeres, and centromeric repeats.
12. Denaturation & Renaturation: DNA melting temperature ($T_m$), factors influencing $T_m$ (GC content, salt concentration), hyperchromic shift, and $C_0t$ kinetic curves.

High-Yield Preparation Topics

• PCR and Primer Design: Melting temperatures, primer dimer formation, annealing temperatures ($T_a = T_m - 5^\circ\text{C}$).
• Enzyme Inhibitors: Distinguishing competitive, non-competitive, and uncompetitive inhibition using Lineweaver-Burk plots.
• Biochemical Assays: Standard clinical laboratory diagnostic principles utilized in tertiary diagnostic centers like AFIP.
