Influenza viruses bind through hemagglutinin onto sialic acid sugars on the surfaces of epithelial cells
Ans; The nucleus of eukaryotic cells is where DNA is replicated in a normal cell. A DNA virus replicating in this cell would then have to replicate in the nucleus since all the proteins for DNA replication and RNA transcription are there. RNA on the other hand is translated in the cytoplasm by ribosomes on the endoplasmic reticulum. Since RNA viruses don't need to transcribe DNA to RNA (which happens in the nucleus) they can just start the translation process in the cytoplasm.
Proteins, known as motor proteins, move themselves and cargo along the microtubules.
