Hematopoietic stem cells are found in Spleen Bone marrow Lymphoid organs Skin4. Gram-positive bacteria are further classified at generic and species level by analysis of: Cell wall Proteins Cell membranes DNA 5. The change of one conformation of a protein into another is called: Apoprotein transition Apoprotein transversion Allosteric transition Allosteric transversion6. Townsend's cordgrass (Spartina X townsendii) is formed as a result of: Grafts Intergeneric hybridization Cultivars Interspecific hybridization7. The production of a wild-type phenotype in bacteria when two different mutations are combined in a diploid is called: Back-karyotyping Genetic Complementation Gene replacement8. A functional genetic unit within which two mutations cannot complement is called: Cistron Muton Recon Polycistron9. In E. coli the complementation test is done on Heterokaryons Haploids Merozygotes Transformation10.
