Your answer: —  Â·  Correct: B
Explanation

The process of copying genetic information from one strand of DNA into RNA is termed transcription. This fundamental biological process involves using a DNA sequence as a template to synthesize a complementary RNA molecule, typically messenger RNA (mRNA) [2]. During transcription, the enzyme RNA polymerase binds to a specific region of the DNA, unwinds the helix, and joins RNA nucleotides to form a transcript that carries the genetic instructions from the nucleus to the cytoplasm. This represents the first step of the 'Central Dogma' of molecular biology, where genetic information flows from DNA to RNA [3]. In contrast, replication is the process of duplicating DNA, translation is the synthesis of proteins from an mRNA template, and mutation refers to permanent changes in the DNA sequence [1].
