Answer:
The correct order would be
1. An enzyme (RNA polymerase) binds to the parent DNA molecule or gene of interest.
↓
2. The double stranded-DNA gets separated at the location where the enzyme attaches.
↓
3. RNA nucleotides, complementary to nucleotides present in the parent DNA molecule, make bonds with the bases on a leading strand of the DNA.
↓
4. The RNA nucleotide chain forms an SS RNA (single-stranded RNA) molecule with the use of a DNA strand as a template.
↓
5. When a stop codon is reached, the RNA strand gets separated from the parent DNA molecule, leaves the nucleus, and enters the cytoplasm.
↓
6. During the final step, the separated strands of DNA rejoin.
The process transcription can be divided into three main steps:
Initiation: RNA polymerase associates with the promoter region of the gene of interest. It results in the separation of two strands of the DNA which forms the transcription bubble.
Elongation: RNA polymerase forms the RNA polymer on the template strand of the DNA. The RNA nucleotides based on the complementarity of template strand forms a single-stranded RNA molecule.
Termination: As soon as the RNA polymerase reaches the termination sequence of the template strand, it dissociates from the DNA resulting in the termination of the transcription.
Consequently, the newly synthesized RNA molecule is separated and the DNA rejoin.
