Non-chordata (animals without backbone) - General characters and classification up to classes (salient features of classes of Invertebrate phyla not to be given) with suitable examples of the following phyla: Protozoa, Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca and Echinodermata. Chordata (Animals with backbone) - Fundamental characters and classification of chordata up to subphyla - Hemichordata, Urochordata, Cephalochordata and Vertebrata with suitable examples. Subphylum Vertebrata - Salient features with examples of (i) Subphylum Pisces: Class Chondreichthyes and Class Osteichthyes); (ii) Superclass Tetrapoda: Amphibia, Reptilia, Aves and Mammalia. Differences between non-chordates and chordates.

Brief account of moriculture: definition, methods (row and pit systems) and its importance. Types of silk - mulberry and non-mulberry (Tasar, Eri and Muga). Diseases of mulberry silkworm - Pebrine, Muscardine or Calcino, Flacherie and Grasserie (Listing of diseases and causative organisms only).

Aquaculture: Definition. Areas - fin fisheries and shell fisheries. Pisciculture: definition, capture fisheries and culture fisheries. Inland fisheries - procedure. Monoculture, monosex culture and polyculture (composite fish farming) - meaning with examples.

Dairy: Definition. Types of indigenous cattle with examples based on utility - draught, milching and dual purpose (Cow breeds - Sindhi, Sahiwal, Amrithmahal, Hallikar, Ongole and Haryana; Buffalo breeds - Murrah, Surti, Mehsana and Nagpuri). Examples of high yielding exotic breeds (Holstein, Red Dane, Jersey and Brown Swiss). Nutritive value of milk. Utility of cattle - biogas, leather, gelatin and organic manure.

Poultry: Definition. Types of indigenous fowls with examples based on utility - layers, broilers and dual purpose (Aseel, Chittagong, Ghagus, Basra and Kadaknath). Examples of exotic breeds (White Leghorn, Cornish, Rhode Island Red Plymouth Rock and Newhampshire). Giriraj - origin and salient features.
Nutritive value of egg. Diseases ( Respiratory mycoplasmosis, Fowl pox candidiasis, Raniketh and Fowl cholera) - Mentioning of diseases and causative organisms only.

Vermiculture: Definition and procedure. Vermicompost - degradation of organic wastes and role of Earthworm in soil fertility.

Molecular Biology: Nucleic acids: DNA - Occurrence, DNA as the genetic material (with the experiment of Avery as evidence), chemical composition, structure (Watson - Crick model), Semiconservative method of replication. RNA - Occurrence, chemical composition, brief account of structure and functions of genetic RNA, rRNA, mRNA and tRNA (clover - leaf model).

Gene: The gene, the genetic code and genetic control of protein synthesis - Concept of gene (prokaryotic and eukaryotic), genetic code and its characteristics, genetic control of protein synthesis (transcription and translation) and Lac operon concept.

Biotechnology: Introduction: Scope of biotechnology.

Genetic Engineering: Introduction; Tools used in genetic engineering - Vectors (plasmid - pUC18), Enzymes (REN and Ligase), Host cell (E.coli) and Bioreactors.
Recombinant DNA technology and its applications: Insulin synthesis to be used as an example.
A brief account of: DNA fingerprinting, Gene therapy, Human genome project, Monoclonal antibodies.
