E. coli cells grown on 15N medium are transferred to 14N medium and allowed to grow for two more generations (two rounds of DNA
replication). DNA extracted from these cells is centrifuged. What density distribution of DNA would you expect in this experiment? A) one high-density and one low-density band
B) one intermediate-density band
C) one high-density and one intermediate-density band
D) one low-density and one intermediate-density band
Plant cells and animal cells undergo the same cellular processes during mitosis.
The centrioles absent in the plant.
Animals cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
<em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each new nuclei.</em>
<span>Tetraphenylcyclopentadienone has five conjugated aromatic rings. Its structure suggests that it is highly conjugated. With this structure, it absorbs the energy from wavelengths of colors other than violet and reflects the energy from violet wavelengths.</span>
