Why do RNA viruses replicate in cytoplasm? How is transcription different in eukaryotic and prokaryotic cells? Why is DNA replication important? Why is interphase the longest phase of the cell cycle? What are the main differences between eukaryotes and prokaryotes?
Bacteria reproduce bybinary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). What can reproduce sexually or asexually?
Why are viruses not classified as prokaryotes or eukaryotes? How are RNA and DNA used to make proteins? How are viruses different from eukaryotic cells? Describe how most eukaryotic genes are controlled Why is methionine formylation in prokaryotes?

[139–146]. AsChlamydia, these viruses can undergo an alternative infection cycle, entering a quiescent state (latency), with low grade viral infection that does not cause cell lysis, from which they subsequently can be reactivated. However, the cell type in which this occurs is usually not ...
