MCQs-Biology-Basics in agricultural biology Welcome to your Basics in agricultural biology 1. Which of the following is true about fatty acids? Fatty acids are present in the cell wall Fatty acid generally contain more than one carboxylic groups Long carbon chain containing acids These are the highly polar acids None 2. In which crop higher amylose and amylopectin is desirable trait? Pulses Oilseeds Cereals Cotton None 3. What is IPC International pulse corporation Inter parental crosses Integrated pest control None of the above None 4. 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 5. Non-sense mutation Premature termination of translation Premature termination transcription Incorporation of chemically different amino acid in a protein None of the above None 6. What is the scientific name of rice Oryza sativa Triticum aestivum Brassica juncea Vigna radiata None 7. Which of the following is not a physical mutagen Gamma rays X-rays Electron beam Ethyl methane sultanate None 8. 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 9. 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 10. What is the unit of yield? Kg Kg/ha Kgha Kg/annum None 11. 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 12. What is the harvest index? It is the ratio of the grain yield per unit above ground biomass It is the ratio of grain yield and total plant biomass The ratio of plant biomass to the total grain yield It is the maximum yield produced by a cultivar per unit area None 13. Which of the following is not the essential trait oil crop improvement? Seed yield Total oil content Early maturity Amino acid content None 14. What is the difference between two way cross and three way cross? Two way cross is performed between two pure lines and three way cross is performed between F1 plants and a pure line Two way cross is made between two F1 plants, three way cross is performed between F1 plants and a pure line Three way cross offers more genetic variability as compared to two way cross Both are same I and III None 15.
