  **SAQ** 1. **Genetic Code and Wobble Hypothesis for Codon-Anticodon Interactions**    **Genetic Code**:    - The genetic code is a set of rules by which information encoded in DNA or mRNA sequences is translated into proteins by living cells. It is universal, nearly identical among all organisms, and consists of 64 codons.    - Codons are sequences of three nucleotides, each codon specifies a particular amino acid.    - There are 61 codons for amino acids and 3 stop codons (UAA, UAG, UGA) which signal the termination of protein synthesis.    **Wobble Hypothesis**:    - Proposed by Francis Crick, the wobble hypothesis explains the flexibility in the base-pairing rules between the 5' base of the tRNA anticodon and the 3' base of the mRNA codon.    - The third base of the codon (3’ end) and the first base of the anticodon (5’ end) can form non-standard pairings, allowing a single tRNA to recognize multiple codons....

  ## SAQ ### 1. Define a balanced diet. Discuss protein-energy malnutrition with the nutritional importance of proteins. **Balanced Diet:** A balanced diet provides all essential nutrients in the right proportions to maintain health, growth, and proper body function. It typically includes: - Carbohydrates: for energy. - Proteins: for growth, repair, and enzyme production. - Fats: for energy, cell function, and absorption of vitamins. - Vitamins and minerals: for various biochemical functions. - Water: for hydration and physiological processes. - Fiber: for digestive health. **Protein-Energy Malnutrition (PEM):** PEM occurs when there is a deficiency of proteins and calories in the diet. It is prevalent in developing countries, particularly among children. PEM manifests in two major forms: - **Kwashiorkor:** Characterized by edema, an enlarged liver, skin lesions, and hair changes. It results from protein deficiency with adequate caloric intake. - **Marasmus:** Characterized by seve...
