DNA replication A. is constantly happening in a cell. B. does not require proteins. C. occurs in the cytoplasm of the cell. D. occurs in G1 of interphase. E. takes place in the nucleus of the cell. Describe the process of DNA replication. ...
For example, if a cell has 2 picograms of DNA before the S phase, it will have 4 picograms after replication. However, the number of chromosomes remains the same; they are simply duplicated. 4. Conclusion: The stage in which DNA replication takes place is the S phase of interphase. ...

These extracts also assemble purified DNA into pseudo-nuclei, structures closely resembling normal interphase nuclei. In this paper we show that although less than 60% of purified DNA is assembled into pseudo-nuclei, DNA replication takes place only within these pseudo-nuclei. Further,...
Just as in prokaryotes, several proteins load onto the origin of replication in a specific order to control replication initiation in eukaryotes. In eukaryotes the cell cycle consists of a “rest” period called interphase, alternating with mitosis, the process of cell division (see Fig. 10.29 fo...
(CSFV), although this restriction does not affect virus entry. In the case of HBV, SERINC5 interferes with the glycosylation of the HBV envelope glycoproteins, thereby suppressing virion production [21]. In the case of CSFV, SERINC5 inhibits virus replication by enhancing MDA5-mediated type I ...
To solve the question, we need to identify the correct answers for X and Y based on the information provided about DNA replication and the cell cycle in eukaryotes.1. Understanding the Cell Cycle: - The cell cycle consists o
