Facilitates the roots of plants going down towards gravity and the stems to rise up away from gravity. ... Thus, the difference is that geotropism is driven by gravity and phototropism is driven by light.
Hey,
option (C) is right ...
It is controlled by negative feedback loop.Let's say you have high glucose level in your blood,that will be registered and pancreas will produce more insulin to keep it in the normal range.Therefore by negative feedback loop it will regulate homeostasis
The correct answer is: B) recognition of the prokaryotic promoter by RNA polymerase
The similarities between prokaryotic and eukaryotic transcription are that DNA is template used for the mRNA synthesis and that this is process is facilitated by the enzyme RNA polymerase.
One of the difference between this process in eukaryotes and in prokaryotes is the promoter region: eukaryotes contain TATA box and CAT box, while prokaryotes don’t (they have Pribnow box that is similar to the TATA box). Promoter region in prokaryotes is always upstream to the start site, while in eukaryotes it can be downstream.
