Answer:

A. centrosome

Explanation:

  • The centrosome is known as the main microtubule-organizing center in the animal cells. 
  • The centrosome constitutes of two centrioles and is surrounded by the pericentriolar material which is nothing but a structured matrix of proteins. 
  • It is the center through which the microtubules emerge.
  • In animal cells, the centrosome is associated with the formation of spindle fibres.

kumpel [21]

The correct option is D.

Cellular respiration is the process by which the body breaks down the sugar molecules that are eaten in food with the aid of oxygen and covert them into energy, carbon dioxide and water are also produced as by products. Cellular respiration and fermentation are both involved in the breaking down of sugars but cellular respiration occurs in the presence of oxygen while fermentation occurs in the absence of oxygen. Carbon dioxide is breath out by the lungs during cellular respiration.

From the sequencing of the human genome, we believe that there are approximately 21,000 protein-coding genes in the genome, of w
Nadusha1986 [10]

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.
