Fundamental genetics Welcome to your Fundamental genetics 1. Auxotrophic mutants are Able to grow on minimal medium Are the mutants produced after the transfer of the genetic material from donor to recipient Fail to grow unless and until supplied with one or more specific nutritional factor The one who posses the antibiotic resistance plasmid None of the above. None 2. Which of the following is not an autosomal disorder? Cystic fibrosis Phenylketonuria Pseudoachondroplasia Red-Green colourblindness None 3. Which of the following is NOT TRUE about the genetic transfer between eukaryotes and prokaryotes? In both the groups, genetic transfers requires the donor and recipient individuals Physical contact between is essential Equal amount of the nuclear material is contributed by both the participants None of the above None 4. Which of the following is CORRECT about the organelle genome? DNA is organised at the Nucleolar Organiser regions DNA is organised at nucleoid region Organeller genome shows histone associated coiling Histone associated coiling is observed in cpDNA but not in the mtDNA None 5. Which of the following is true about genome sequencing and mapping, Genome sequencing can identify the genes, their function as well as define their position Most of the genes identified by the genome sequencing are of unknown function Gene mapping helps to associate the phenotypic data with the gene sequences All of the above 2 & 3 None 6. Which of the following is not true about the gene inheritance All autosomal and sexual chromosomal allele pairs inherit independently Organelle genes inherit independent of nuclear genes Meiosis leads to equal distribution of all the genetic material from the genome between gametes Recombination may lead to the violation of mendelian laws of segregation None 7. None 8. None 9. What is plasmid? Plasmid is a self replicating extrachromosomal DNA commonly present in bacteria It can self replicate but it does not have its own origin of replication It has its own origin of replication It can recombine with the chromosomal DNA All of the above 1, 3, & 4 None 10. Advantage/s of using bacterial system as a model for genetic studies is /are? Bacteria are fast dividing They take little space to grow They are convenient for mutagenesis All of the above None Please fill in the comment box below. Time's up
