Answer #1

Ans - Coronaviruses recognize a variety of host receptors, infect many hosts, and are health threats to humans and animals. The receptor-binding S1 subunit of coronavirus spike proteins contains two distinctive domains, the N-terminal domain (S1-NTD) and the C-terminal domain (S1-CTD), both of which can function as receptor-binding domains (RBDs). S1-NTDs and S1-CTDs from three major coronavirus genera recognize at least four protein receptors and three sugar receptors and demonstrate a complex receptor recognition pattern

1. Multiple choice: Self-reactive B cells can be eliminated from the repertoire at several stages of B cell maturation, including immature B cells that have already emigrated from the bone marrow into the circulation. This latter stage of tolerance induction is critical because: A. Not all self-antigens are expressed or present in the bone marrow during B cell development. B. Immature circulating B cells are more sensitive to antigen stimulation than the developing B cells in the bone marrow. C....
