The paper requires students to answer all questions, covering fundamental concepts in microbial genetics. Question One (18 marks) focuses on defining key terms such as Merozygote, Constitutive, Transposons, Restriction enzyme, Introns, and Okazaki fragment. It also requires students to differentiate between the genetic materials of prokaryotic and eukaryotic cells and to draw and label the structures of tRNA and rRNA. Question Two (22 marks) delves into the AMES test, asking for a full description of its principles, aided by labeled drawings, for the detection and isolation of mutant bacteria. Additionally, it requires a discussion of DNA repair mechanisms. Question Three (20 marks) addresses DNA as an informational molecule, asking for a historical account from 1928, 1944, and 1952 to prove this concept. It also requires descriptions of aspects of gene structure and the genetic code, including degeneracy, sense codon, exons, antisense strand, and leader sequence. Question Four (15 marks) requires a comprehensive description of the entire process of protein synthesis, supported by labeled structures such as tRNA. Finally, Question Five (25 marks) focuses on bacterial genetic information transfer, requiring descriptions of conjugation (F+, HFr, and F'), transformation, and transduction. The examination aims to comprehensively assess students' knowledge of microbial genetics and genetic recombination.Item Introduction to Microbiology: MIC 211, Degree Examinations June 2023(University of Fort Hare, 2023-06) Ntozonke, N.; Nontongana, N.; Ngwenya, E.G.Item Mendelian Genetics and Chromosomal Inheritance: MIC 212, Degree Examinations June 2023(University of Fort Hare, 2023-06) Ngwenya, E.G.; Nontongana, N.; Ntozonke, N.
