Cell The Unit of Life Test No-15 August 5, 2017admin0 Comments CategoriesCell The Unit of Life NEET Foundation Class VIII-Botany-Cell The Unit of Life 1. Organelles involved in the protection of cell from microbes and effect of H2O2 respectively are Lysosomes and glyoxysomes Peroxysomes and glyoxysomes ER and golgi complex Lysosomes and peroxysomes 2. The protein necessary for the organization of ribosomal subunits are synthesized by Golgi complex Peroxysomes Ribosomes Smooth endoplasmic reticulum 3. Chromsomes are the Physicasl basis of heredity Physical basis of life Chemical basis of heredity Dynamic centres of the cell 4. Ends of chromosomes exhibiting polarity and offering stability are known as Knobs Chromomeres Satellites Telomeres 5. Size of chromosome can be measured easily in Metaphase S-phase Telophase Interphase 6. V- shaped anaphasic chromosome is Metacentric Sub-metacentric Acrocentric Telocentric 7. Histone octamer acts as the core of the nucleo-some. The type of histone which is not a component of octamer? H2A H2B H4 H1 8. Number of H1 proteins associated with a 10 nucleosomes in chromatin fibre is 9 10 11 12 9. A chromosome with centromeres and arms in 1:1 ratio is Metacentric Sub metacentric Acrocentric Telocentric 10. The ratio between Histone ‘2’ and Histone ‘!’ associated with eukaryotic DNA, respectively ? 2:01 1:02 1:04 4:01 11. Chromosome morphology can be best studied during Inter phase and prophase Prophase and Metaphase Metaphase and Anaphase naphase and Telophase 12. The ratio of H1 and H3 proteins in chromatin is 1:02 2:01 1:01 1:04 13.
