The process of copying genetic information from one strand of DNA into RNA is termed as -

Transcription

The correct answer is Option (3) → Transcription

The process of copying genetic information from one strand of the DNA into RNA is termed as transcription.However, unlike in the process of replication, which once set in, the total DNA of an organism gets duplicated, in transcription only a segment of DNA and only one of the strands is copied into RNA.

A transcription unit in DNA is defined primarily by the three regions in the DNA :
(i) A Promoter
(ii) The Structural gene
(iii) A Terminator
