Answer:
Common examples of social issues: Poverty and Homelessness, Climate Change, Civil Rights and Racial Discrimination, etc.
Explanation:
There's so much more examples of social issues down the list, but that'll take to long, these are enough for now.
Answer:
Nuclear envelop disintegration does not take place before the start of mitosis.
Explanation:
Mitosis is the process in which one cell divides into two daughter cells. In eukaryotes, somatic cells divide by mitosis and are identical to parent cells.
Before the start of mitosis, cells are in the interphase in which the cell's DNA material become double by replicating, cells organelle proliferates and the cell grows in size.
Prophage is the first stage of mitosis in which the genetic material becomes condense to chromosomes, mitotic spindles start developing, the nucleolus becomes disappear and nuclear membrane disintegrates.
Therefore nuclear envelop disintegration occurs during the first stage of mitosis, not before mitosis.
Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
