MCQs-Biology-Basics in agricultural biology Welcome to your Basics in agricultural biology 1. Which of the following is not the essential trait oil crop improvement? Seed yield Total oil content Early maturity Amino acid content None 2. Which of the following category of plants have more evolutionary advantage? Cross pollinating plants, because it helps in creating newer genetic variability Self pollinating plants, because the genome stays uncontaminated with the foreign DNA Vegetatively propagating plants Plants with longer lifespan None 3. In which crop higher amylose and amylopectin is desirable trait? Pulses Oilseeds Cereals Cotton None 4. Which of the following proteins are involved in the degradation of the other proteins? Ubiquitins Receptor kinases Ion transporters Histone proteins None 5. Silent mutation is Incorporation of chemically different amino acid in a protein Incorporation of chemically same amino acid in a protein Premature protein Structurally different protein None 6. In cross breeding which of the following increase the probability of obtaining targeted phenotype? Using genetically different parents Crossing between two F1 plants Large F2 population Intragenic crossing None 7. What is IPM Integrated pest mantainance Integrated pest management Innovative plant mutagenesis None of the above None 8. Phenotypic markers are? Morphological traits associated with agronomically important trait Any modified phenotype is a phenotypic marker Any mutational change without visible alterations None of the above None 9. Different colours of flower are because of… Anthocyanins Carotenoids Chlorophylls Proteins None of the above I and II None 10. The full form of the TILLING is Transcriptional initiation lipid layering and integration Topology illustrating infographics Targeting induced local lesion in genome None of the above. None 11. What is genetic recombination? Broken DNA after repair sometimes generate newer genetic combinations Homologous chromosome cross over that leads to new genetic combination Non homologous end joining repair mechanism also leads to the genetic recombinations All of the above None 12. Which of the following may not be considered as phenotypic marker? Dwarfness Silent mutation in DNA polymerase Yellow green leaf color Curly leaves None 13. What is the scientific name of rice Oryza sativa Triticum aestivum Brassica juncea Vigna radiata None 14. Why linolenic acid can not be stored for longer time? Because of the inefficient storage methods Residual impurities affect the quality of the linolenic acid It oxidises rapidly It is highly flammable None 15.
