Question

Which of the following are required for the process of transcription?

O tRNA and RNA polymerase
O DNA and DNA polymerase
O RNA polymerase and the promoter
O transcription factors and amino acids

Answer 1

For eukaryotic transcription to occur, transcription factors must first bind to the promoter region to then recruit RNA polymerase, making RNA polymerase and the promoter the required components for transcription. Considering as a, b, c and d, option number C is correct.

Step-by-step explanation:

The process of transcription in eukaryotic cells requires several components. Unlike in prokaryotes, eukaryotic RNA polymerase cannot bind directly to DNA. It needs the help of transcription factors to first bind to the promoter region and then recruit the RNA polymerase to initiate transcription. Therefore, the components required for the process of transcription are RNA polymerase and the promoter, which is the correct answer to the student's question out of the provided options.

The eukaryotic transcription process involves a complex interplay of multiple factors. Transcription factors like the TFIID complex, which includes a TATA-binding protein, and other TFII factors are essential for forming the pre-initiation complex. Once the complex is formed, the RNA polymerase can then begin the synthesis of the RNA molecule, proceeding in the 5'→3' direction and using the underlying DNA as the template strand.
