(EnR-B-017 to 021)

Chapter 30:  (Lippincott)

  • No need to do the the structure of DNA as it is not the part of ur syllabus 
  • Start from (III-Steps in ….) pg no 462 to 475
  • Although whole chapter is imp but the most important topics are below:
  •  Replication strand and required proteins ( DNA A , DNA helicase and Single strand binding protein) v.imp
  • Topoisomerases type 1 and 2 (their difference also and their inhibitor green box) and supercoilimg (v.v.imp)
  • Leading and Lagging strand
  • Primase and primosome 
  • DNA Polymerase III ( proofreading and exonuclease activity) imp 
  • DNA ligase 
  • Eukaryotic DNA replication complete 
  • Telomeres and Telomerases v.v.imp (cover entire topic given in eukaryotic DNA replication)
  • Eukaryotic DNA organization 
  • DNA Repair (v.v.imp)

Many mcqs are given from this topic 

  • Cover complete topic all 4 types and their clinical correlates i.e Xeroderma Pigmentosum & Lynch Syndrome (v.v.imp)
  • Exonuclease & Endonuclease imp
  • For Central Dogma Concept You can use medicnetic/ medico express 
  • Fig 30.21, 30.23, 30.24 (v.v.imp)

(EnR-B-022 to 024)

Chapter 31: (Lippincott)

  • No need to do structure of RNA as not a part of syllabus 
  • Start chapter from (III-Prokaryotic) pg no 484 to 493
  • Prokaryotic Gene Transcription 
  • Prokaryotic RNA polymerase 
  • RNA synthesis (Complete)
  • Associated antibiotics (Rifampin and Dactinomycin) v.imp
  • Eukaryotic Gene Transcription
  • Eukaryotic RNA polymerases 1,2,3 
  • Promoters, Transcription factors, Enhancers and Inhibitors associated with RNA polymerase II
  • Post Transcriptional Modification of RNA (v.v.imp)

(EnR-B-025 to 027)

Chapter 32: (Lippincott)

  • Skip initail headings of Genetic code 
  • Start chapter from Mutations 
  • Cover All mutations and their examples given in the text (v.imp)
  • Skip components required for translation and start from Codon Recognition by Transfer RNA 
  • Wobble Hypothesis (v.v.imp) for both written and viva 
  • Steps in translation including initiation (it’s sequences also), elongation and termination 
  • Shine Dalgarno sequence (imp)
  • For Steps of Translation Fig 32.13 is quite helpful 
  • Steps of fig 32.13 and Actions Of 5 Antibiotics given in fig 32.13 (v.imp)
  • Co and Posttranslational modifications ( v.imp)

(EnR-B-028)

Chapter 33: (Lippincott)

Understand Regulatory sequences and molecules first 

  • Regulation Of Prokaryotic Gene Expression (imp)
  • Operon definition
  • Operator and Inducer 
  • Lactose Operon (Lac Operon) it is v.v.v..imp topic (Cover this topic completely including it’s regulation imp) and Fig 33.4 v.v.imp
  • Tryptophan Operon (v imp) complete 
  • Regulation Of Eukaryotic Gene Expression (imp)

Although only 2-3 topics are important from this portion but in LOs it is not clearly mentioned that only that 2-3 topics are included so it is preferable to do this completely at least once with special emphasis on following topics 

  • Messenger RNA editing ( v.imp)
  • Messenger RNA stability 
  • Iron Metabolism (v.v.v.imp & our Proff Seqs) shortlist on fig 33.14 as it is enough
