WebCell cycle checkpoints. A checkpoint is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues and "decides" whether or not to move forward with division. There are a number of checkpoints, but the three most important ones are: start subscript, 1, end subscript. start subscript, 1, end subscript. /S transition. WebThe life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis.

WebProkaryotic and eukaryotic cells make up prokaryotes and eukaryotes, respectively. Prokaryotes are always unicellular, while eukaryotes are often multi-celled organisms. Additionally, eukaryotic cells are more than 100 to 10,000 times larger than prokaryotic cells and are much more complex. The DNA in eukaryotes is stored within the nucleus ... WebEukaryotic cells have 10–10 000 times as much DNA as bacteria, yet they are not vastly more sensitive to DNA damage, despite the general similarity of their repair mechanisms. The eukaryotic secret lies in its control of the cell cycle to block DNA replication until the damage is repaired. Cell cycle arrest after detection of DNA damage ... join by tenon and mortise
