Question

fill in the blank question
during transcription, □ is used as a template to produce □.

Explanation:

In the process of transcription (a key process in molecular biology, part of the central dogma), DNA (specifically one of the DNA strands, the template strand) serves as the template. The enzyme RNA polymerase uses this DNA template to synthesize a complementary RNA molecule (such as mRNA, though other types like tRNA or rRNA can also be produced). So the first blank should be "DNA" (or more precisely "a DNA strand" or "the template DNA strand") and the second blank should be "RNA" (or a specific type like "mRNA" depending on context, but generally "RNA" is accurate for the basic concept of transcription).

Answer:

First blank: DNA
Second blank: RNA
