Detailed explanation-1: -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-2: -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-3: -DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand.
Detailed explanation-4: -“Both the strands of DNA are not copied during transcription”.
