Question

whats transcription

Answer 1

The process of copying genetic information from one strand of DNA onto RNA is termed as transcription.

The principle of complement base pairing governs this process only that now adenosine now pairs with uracil instead of thymine, as in DNA strands. A fragment of only one strand of DNA gets copied into the RNA.

The transcription unit of DNA consists of three regions--

a] The promoter- it is the binding site for RNA polymerase where transcription is initiated.

b] The structural gene - It codes for enzymes or proteins for structural functions.

c] The terminator - It is the region where transcription ends.

So, transcription can be summed up as consisting of three steps - Initiation, Elongation and Termination.

Transcription is an important cellular process whose purpose is to make RNA copies of individual genes that the cell can use in various processes. It helps to transfer important information from the DNA to cellular structures to make required proteins.
