Answer:

Transcription is the cellular process of RNA synthesis by decoding the information contained in a DNA fragment

Explanation:

Transcription is the process by which the genetic information contained in a fragment of DNA called 'gene' is used as a template to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently used to synthesize a protein by the process of translation. In eukaryotic organisms, transcription involves a DNA template strand, which contains both non-coding (i.e., promoter, introns) and conding (i.e, exons) regions, and an RNA polymerase that adds nucleotides to the growing RNA strand using as a template a DNA strand. Both in prokaryotes and eukaryotes, transcription occurs in three basic steps: 1-initiation, where DNA strands separate, 2- elongation, where the RNA polymerase moves on the DNA sequence to synthesize an RNA molecule, and 3-termination, where transcription terminates depending on the sequence in the RNA (eukaryotic transcription has an additional step known as RNA processing).
