Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase

(along with its sigma subunit) can initiate transcription on its own. (b) RNA polymerase (along with its sigma subunit) requires the general transcription factors to assemble at the promoter before polymerase can begin transcription. (c) the sigma subunit must associate with the appropriate type of RNA polymerase to produce mRNAs. (d) RNA polymerase must be phosphorylated at its C-terminal tail for transcription to proceed.

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.

Which process occurs only in autotrophic organisms? Calvin cycle chemiosmosis Krebs cycle proton pump mechanism
tankabanditka [31]
The answer to this question should be: Calvin cycle

Calvin cycle is a chemical reaction that was done in the chloroplast of a plant. This is one of the reactions in photosynthesis. In Calvin cycle, carbon dioxide and water will be used to make carbohydrates(glucose). This reaction is forming energy using the sunlight so only autotrophic organism capable that will be able to do it.

4. What is an example of positive feedback?
Shtirlitz [24]

Answer:

C

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.
