What does the tryptophan bind to when it is present in E. coli?

2 answers:

5 0

The tryptophan operon found in E coli is a group of genes that encode the enzyme that E coli use for biosynthesis. The operon can be turned on and off. The operon is regulated and controlled by TRP Repressor. When bound to tryptophan, the trp repressor blocks the expression of the operon.

The tryptophan operon is a repressible operon meaning that it is active when there's less TRP available. Therefore, to control the TRP operon when tryptophan is available, the tryptophan molecule must bind to the TRP repressor.

Puritan disagreement over the use of inoculations for smallpox reflected tensions over what broader issue?

Vadim26 [7]

<h2>Smallpox Vaccine</h2>

Explanation:

The smallpox vaccine is the best way to forestall smallpox.
The immunization is produced using an infection called vaccinia, <em>which is another pox-type infection identified with smallpox. </em>
Immunization began as a technique for the anticipation of smallpox by conscious presentation of material from smallpox pustules into the skin.
This for the most part delivered a less extreme contamination than normally procured smallpox, yet at the same time initiated invulnerability to it.
It created insusceptibility as a rule, however it likewise murdered a few people and added to smallpox outbreaks.

The effects of anaerobic conditions how would anaerobic conditions (when no o2 is present) affect the rate of electron transport

Romashka-Z-Leto [24]

Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.
