Final answer:

In transcription, essential components such as a DNA template, RNA polymerase, promoter region, transcription factors, and nucleotide triphosphates are required. The option 'none of the others' is not required for transcription as it does not represent a biological element involved in the process.

Step-by-step explanation:

The synthesis of RNA from a DNA template, known as transcription, requires several components. These include a DNA template strand, RNA polymerase enzyme, a promoter region to initiate transcription, transcription factors to aid the RNA polymerase in binding to DNA, and the nucleotide triphosphates (ATP, UTP, GTP, CTP) as building material for the RNA strand. However, among the options provided, the one that is NOT required for transcription is 'none of the others', because all listed options are essential components of the transcription process.
