Transcription is:

the synthesis of proteins from information on a mrna

the synthesis of brain cells by neurokinetic means

the synthesis of nucleotides from a dna molecule

the synthesis of rna from a dna template

The synthesis of RNA from a DNA template.

Explanation:

We know that transcription is the first step in gene expression. In the transcription process, information from a gene is used to build a functional product such as a protein. The primary goal of transcription is to produce an RNA copy of a gene's from a DNA sequence.

For a protein-coding gene, the RNA copy, or transcript, carries that information that is needed to build a polypeptide.  

Eukaryotic transcripts need to go through some processing steps before starting of translation into proteins.
