These
instructions that produces a specific protein is called the Gene. A gene is a region
of DNA that encrypts purpose. A chromosome comprises of a long strand of DNA that
involves many genes. A human chromosome can contain up to 500 million base pairs
of DNA that has thousands of <span>genes.</span>
Answer:
A plant cell
Explanation:
In the given question, a stage of a cell has been described during cell division.
The characteristic of this cell division are:
1. Nuclei are formed at opposite poles- shows that it is the stage of cell division
2. The formation of cell plate- the cell plate is formed in the middle of the cell which indicates that the cell is a plant cell.This cell is a plant cell as the cell plate is formed only in the plant cells and not in the animal cell in which the contractile rings are formed.
Thus, A plant cell is correct.
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.
