Fundamental genetics Welcome to your Fundamental genetics 1. The total length of the DNA in each human cell is 2 meters 2X10 13 meters 1 meter 0.0006 mm None 2. Set of the environment-phenotype relations for a given genotype is termed as, Epigenetics Epistasis Norm of reaction Epimutations None 3. How many DNA molecules are present in one chromosome 1/2 1 2 None of the above. None 4. Allelic variation contributes to continuous as well as discontinuous variation in the population, True False 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. 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 7. 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 8. In WZ pattern of inheritance male parent bear the ZZ pair of chromosomes and female parent bear the WZ pair. True False None 9. 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 10. Wild type allele can be dominant or recessive to the mutant allele. True False None Please fill in the comment box below. Time's up
