When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells. Why?
Homework Answers
Strain specific assembly of TMV in vivo is due to RNA and not due to coat protein and that is why reassembled virus sare giving rise to A strain virions as RNA Is of A strain and it is mixed with coat protein of stain B so it won't make B virions unless and until the RNA is from B strain.

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...

Is option 1 false because immortalisation requires whole
episomal form of EBV and 9 proteins and here we are transfecting
with only one protein 2? However, I read in an article that
"Lymphoblastoid cell lines (LCLs) are human B cells latently
infected and immortalized by Epstein-Barr virus (EBV). A mini-EBV
plasmid that consists of less than half the EBV genome can still
immortalize B cells in vitro." which...

1. Griffiths (1928) mixed heat-killed 'THIS' bacteria with 'IIR' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 's bacteria from the dead mouse. How can you explain this phenomenon? When 'R' and 'strains were mixed, the DNA from 'IS' bacteria with the gene responsible for forming capsules transferred to the 'R' bacteria. The gene cause 'R' to transform into...
