Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process of transcription is organized in different steps; put them in the right order.
A
Termination, elongation, initiation
B
Binding, initiation, termination
C
Initiation, binding, elongation
D
Initiation, elongation, termination
Explanation: 

Detailed explanation-1: -Transcription has three stages: initiation, elongation, and termination. In eukaryotes, RNA molecules must be processed after transcription: they are spliced and have a 5’ cap and poly-A tail put on their ends.

Detailed explanation-2: -This is a two-step process. The first step is transcription in which the sequence of one gene is replicated in an RNA molecule. The second step is translation in which the RNA molecule serves as a code for the formation of an amino-acid chain (a polypeptide).

Detailed explanation-3: -The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a).
