Fundamental genetics Welcome to your Fundamental genetics 1. Which of the following is the correct sequence of the chromosomal packaging ? Nucleosome - Solenoid - Supercoil - Chromosome Supercoil - Nucleosome - solenoid - Chromosome Chromosome - Solenoid - supercoil - nucleosome Supercoil - Solenoid -Nucleosome- Chromosome None 2. Which of the following is not related to the study of the genetics? Certain diseases running in the family. Farmers know which crop grows best in their farm Flowers attract the insects Gene None 3. None 4. How many DNA molecules are present in one chromosome 1/2 1 2 None of the above. None 5. In which of the following organism, the process of conjugation was discovered? Escherichia coli Neurospora crassa Bacillus thuringiensis Bacillus subtilis None 6. 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 7. Which of the following scientific approach used by Mendel was/were crucial in his experimentation? Using a pea plant for experimentation because it has short life span Obtaining a pure line for each characters in the beginning of the studies Counting the number of progenies with associated characters All of the above 2 & 3 None 8. 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 9. 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 10. Which of the following is NOT the contribution of the Mendel, Discovery of the patterns of the inheritance Proposed the concept of genes that govern the specific character in plant Identification of the sex linked characters like flower color in pea Proposed alternative forms of the genes None Please fill in the comment box below.
