Question

what is transcription? and whats it product?​

Answer 1

Explanation:

Transcription, the synthesis of RNA from DNA. ... Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein).

Transcription refers to the first step of gene expression where an RNA polymer is created from a DNA template. This reaction is catalyzed by enzymes called RNA polymerases and the RNA polymer is antiparallel and complementary to the DNA template. The stretch of DNA that codes for an RNA transcript is called a transcription unit and could contain more than one gene.

These RNA transcripts can either be used as messengers to drive the synthesis of proteins or be involved in a number of different cellular processes. These functional or non-coding RNA could be transfer RNA (tRNA), ribosomal RNA (rRNA), or direct gene regulation through RNA interference (RNAi) and the formation of heterochromatin.
