Produced during ATP synthase in the mitochondria
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
Answer:
Moistening food and helping to create a food bolus so food can be swallowed easily
Answer:
Well for the onion peel, since its a plant cell...it shall gain water from the solution as it has a lower water potentail,and hence increase in size, becoming turgid and tight, with the cell wall exerting pressure to stop it from bursting.
For the RBC, its an animal cell, and shall also gain water, but since there is no cell wall to support it, it shall soon gain so much water that it shall burst becuase of the pressure, through lysis, and shall die.
Note, the plant cell does not die.
Answer:
Explanation:
This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.
There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.
