How does RNA leader sequence affect Trp operon syst

Biology
1 answer:
Luda [366]4 years ago
3 0

Answer:

The base pairing of complementary regions of RNA leader sequence determines if the transcription will be attenuated at the end of leader sequence or will continue for structural genes.

Explanation:

The RNA leader sequence of trp operon is the site where the transcription is initiated.  

When tryptophan levels are high, translation of sequence 1 of the leader sequence is followed by base pairing between the complementary 3 and 4 regions of the leader sequence. The base pairing forms a terminator like attenuator and stops the expression of structural genes.  

When tryptophan is not present, ribosome pauses at tryptophan codon of region 1 of the leader sequence. Hence, the regions 2 and 3 of the leader sequence base pair and prevents the formation of attenuator by not allowing the region 3 to pair with region 4.

You will research major earthquakes and pick one to answer the following questions:
levacccp [35]
Research major earthquakes on google, or another website. I would go with question 1, Where is your earthquake? I would do the Haiti earthquake where the earthquake is in Haiti. Do more research on Google, because I cannot provide you with a link to an article because Brainly will not allow me to do so. Just research "major earthquakes" in Google and you will be good to go. Hope this helped!
