Detailed explanation-1: -During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Detailed explanation-2: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Detailed explanation-3: -DNA transcription produces a single-stranded RNA molecule that is complementary to one strand of DNA.

Detailed explanation-4: -The result of RNA transcription with RNA polymerase II is a single stranded RNA sequence complementary to the entire length of the gene, usually referred to as the primary (RNA) transcript or precursor messenger RNA (pre-mRNA).
