Which of the following molecules is not required for eukaryotic transcription? a. rna polymerase b. dna polymerase c. rna nucleotides d. transcription factors

B. DNA polymerase

Explanation:

Eukaryotic transcription is the process of synthesizing RNA from DNA in eukaryotes. It requires RNA polymerase, transcription factors and RNA nucleotides. In the initiation phase, RNA polymerase binds to the promoter sequence on DNA with the help of transcription factors. A transcription bubble is created where the DNA strands separate from each other. RNA polymerase binds to the template strand and begins the transcription process. It adds RNA nucleotides to synthesize RNA strand.

DNA polymerase has no role during this process hence it is not required. It is used during replication where it adds DNA nucleotides to form a new DNA strand from existing one.

the answer is: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
