Question

During _______, RNA polymerase slides along the DNA in an open complex to synthesize ______.

Answer 1

During transcription elongation, RNA polymerase tracks along the DNA template strand and synthesizes mRNA in the 5' to 3' direction while unwinding and rewinding the DNA.

Step-by-step explanation:

During transcription elongation, RNA polymerase tracks along the DNA template strand and synthesizes mRNA in the 5' to 3' direction. As the RNA polymerase moves, it unwinds the DNA ahead of it and rewinds it behind, forming an open complex to allow synthesis of complementary RNA nucleotides to the growing strand.
