Answer:
The correct answer is - option A. IKK.
Explanation:
In signal transduction or any other molecular biology process, the upstream or downstream is related to the molecular or cellular events that follow a mechanistic and temporal order.
In TNF signaling involved in cell survival pathway the TRADD- associated complex also is known as TNF receptor-associated death domain complex has a second messenger that activates temporally after the cell membrane receptor known as IKK signaling protein that help in numerous downstream pathways.
Thus, the correct answer is - option A. IKK.
Answer:, microorganisms whose action results in the conversion of nitrates in soil to free atmospheric nitrogen, thus depleting soil fertility and reducing agricultural productivity.
Explanation:
Thomas Hunt Morgan used fruit flies to study genetics for several reasons. First, fruit flies have a short life cycle that lasts an average of just 30 days. This means genetic traits can be studied over dozens of generations in the course of a year. This rapid reproductive cycle is impossible to match in any mammalian model, even mice or rats. Second, fruit flies produce huge numbers of offspring.
