Summary Introduction
Introduction:
Transcription is the process in which single-stranded ribonucleic acid (RNA) is produced from double-stranded deoxyribonucleic acid (DNA). This process takes place inside the nucleus. The DNA is first replicated and then it undergoes a process wherein RNA is formed and finally this RNA is converted into proteins via the translation process.
