Fundamental genetics Welcome to your Fundamental genetics 1. New alleles formed as a result of the mutation in the gene can cause protein molecule to, Function more Function less Lose function Gain new function None 2. Which of the following best describe the role of genes in biology? They can replicate but do not play any role in the structural organisation of an individual They can replicate and carry necessary information required for the unique structural organization In the constantly changing environment they can mutate and help in evolution 2 & 3 None of the above None 3. Which of the following is possible through controlled mating studies? Identification of Genes and their alleles Identification of the relative chromosomal locations of the genes Inheritance pattern of the genes All of the above None 4. Which of the following is not an autosomal disorder? Cystic fibrosis Phenylketonuria Pseudoachondroplasia Red-Green colourblindness None 5. What are prototrophic bacteria? Prototrophic bacteria can grow on minimal medium Prototrophic bacteria are those which require the medium supplemented with special growth promoting nutrients The bacteria those require antibiotics for growth. All of the above I and II None 6. Set of the environment-phenotype relations for a given genotype is termed as, Epigenetics Epistasis Norm of reaction Epimutations None 7. Which of the following is NOT true about the Sutton-Bovery theory of chromosomes? Mendel’s observations were matching with the behaviour of the chromosomes during meiosis Sutton-Boveri theory suggests that genes are located on the Chromosomes Suttone-Bovery theory was proved with the direct evidence None of the above None 8. Davis U tube experiment suggested that Auxotrophic mutants always have the capability to revert back to the wild type For genetic transfer the physical contact between two bacteria is essential When two auxotrophic bacterial cells were mixed Wild type bacteria could grow in the minimal medium because of “cross feeding” No physical contact is required for the genetic transfer between two bacteria None 9. In which of the following organism, the process of conjugation was discovered? Escherichia coli Neurospora crassa Bacillus thuringiensis Bacillus subtilis None 10. Correct sequence of mitotic division is Prophase - Metaphase - Anaphase - Telophase Anaphase- Prophase - Telophase- Metaphase Metaphase - Telophase - prophase - Anaphase None of the above None Please fill in the comment box below.
