You’d like to understand how cell metabolism occurs when DNA is unwound during S phase. Indeed, DNA replication typically does not occur at the same time as RNA transcription. So, how do cells produce the RNA they need to make metabolic proteins when DNA replication is happening? The quick...

It is the time during which a cell performs its function. Interphase also is when preparations for cell division, including DNA replication and replication of organelles, occur. During interphase, the nucleus does not undergo any visible changes in structure and the chromosomes are long and thin....
In which stage of mitosis does DNA replication occur? Which stage of mitosis is most often associated with the beginning of cytokinesis? 11) What is cytokinesis? A) The stage of the cell cycle that happens before the cell is ready to divide its DNA B) The ...
DnaA protein overproduction abolishes cell cycle specificity of DNA replication from oriC in Escherichia coli Initiation of DNA replication from oriC in Escherichia coli takes place at a specific time in the cell division cycle, whether the origin is located on a chromosome or a minichromosome, and...
SARS-CoV-2 RNA genome2 reveals multiple opportunities for antiviral therapeutic targeting, which are all being relentlessly pursued as it can be expected that a cocktail of compounds acting at different steps of the viral life cycle will be needed to efficiently suppress viral replication in vivo....
Alternatively, hapten-binding fragments can be produced through the application of recombinant DNA technology or through synthetic chemistry. Preferred cell lines, obtainable through the methods of the present invention, are those which produce antibody capable of binding to an antigen present on liver...
This result alone gives a hint of the general impediment imposed over cell metabolism by a pressure of 10 MPa, suggesting that critical metabolic pathways for cell replication and survival were impaired. Clusters of ortholo- gous genes (COG) upregulated under pressure were predominantly ...
What protein unwinds and separates DNA strands in DNA replication? What part of the cell contains DNA and RNA and is responsible for growth and reproduction? Which of these processes does not occur in the nucleus? A) DNA replication B) Transcription C) Translation ...
Which of the following does not occur during DNA replication? a. One new strand is formed by continuous synthesis while the other new strand is formed in fragments. b. Cellular processes proofread new strands to check for errors. ...
