B) a short primer, complementary to the DNA template, is required to initiate transcription.

D) GTP serves as the energy requirement for each new phosphodiester bond.
E) the reaction is "semi_Conservative" with respect to the DNA template.

Transcription involves the synthesis of RNA from a DNA template. The energy for the formation of the phosphodiester bonds between nucleotides in the RNA molecule comes from the nucleotide triphosphates themselves (ATP, GTP, CTP, UTP). When these nucleotides are incorporated into the growing RNA chain, pyrophosphate (PPi) is released and subsequently hydrolyzed to two molecules of inorganic phosphate (Pi). This hydrolysis of pyrophosphate drives the reaction forward, making it energetically favorable.
