Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
Explanation:
The tropical rainforest is made up of a dense network of trees, shrubs and vegetation.
This zone on earth is the most biodiverse on the earth surface. It receives the highest insolation of all places on earth and so radiant energy here is very high.
- Due to this, the net productivity is very high.
- This implies that a wide range of food is available to support the diverse organisms.
- Also, the wet and dry seasons provides a very conducive weather for most organisms to survive.
Tundra and deserts have low precipitation and the conditions are very harsh.
