Virus envelopes are derived from (AnsCellular membranes and are composed of -lipid bilayers (same composition as the cellular membrane from which they were derived) -viral glycoproteins (spikes sticking out of envelope) Viral envelopes are acquired at the cell membrane by a process called (Ans- Budding Budding (Ans- -viral glycoproteins are inserted to membrane -nucleocapsids associate with glycoproteins and get wrapped in membrane Pathway A of budding (Ans- Some nucleocapsids inter...

How are genomes transported into the nucleus? (Ans- RNP (genome + NP + RNA polymerase complex) starts in the cytoplasm after being dumped from the endosome RNP will get into the nucleus with nuclear pore complexes (gateway for entry and exit sites in nuclear envelope) How do visions enter or exit the nucleus through Nuclear pore complexes? (Ans- Nuclear Localization Signals (NLS): anything that needs to enter nucleus must have this signal (to exit cell must have nuclear export signal) ...
