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.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

the answer would be d : p
