Answer:
The TATA box helps bind the <em>RNA polymerase</em> in the correct place.
Explanation:
The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.
The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.
Answer:
None of the choices would lead to all identical gametes.
Explanation:
Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.
The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
Answer:
A. The ecosystem can support fewer foxes than grasshoppers.
Explanation:
Since the energy has to transfer from organism to organism, it reduces in amount. Since there are more grasshoppers than foxes, than the ecosystem can support grasshoppers easily.
