It helps RNA polymerase recognize the promoter sequence (correct)

It aids in the binding of ribosomes to mRNA

It facilitates the splicing of pre-mRNA

It acts as a proofreading enzyme during transcription

The energy is provided by the binding of RNA polymerase to the template DNA strand

Nucleotide triphosphates provide the energy for bond formation (correct)

Phosphodiester bonds are formed using energy from the hydrolysis of ATP

The energy is derived from the hydrolysis of DNA

DNA helicase, which unwinds the double helix during DNA replication

DNA polymerase I, which removes RNA primers and fills the gaps with DNA nucleotides

Taq polymerase, which synthesizes new DNA strands using existing ones as templates (correct)
