Copying genetic information from one strand of DNA into mRNA is:

Transcription

The correct answer is Option (1) → Transcription

Transcription is the process of copying genetic information from a DNA strand into messenger RNA (mRNA). During this process, the enzyme RNA polymerase reads the DNA template strand and synthesizes a complementary mRNA strand.

Translation is the process where the mRNA is used as a template to synthesize proteins.

Transformation refers to the uptake of genetic material from the environment by a cell, commonly seen in bacteria.

Replication is the process of copying DNA to produce identical DNA molecules for cell division.
