It is the first step of transcription:
Correct answer: C. Binding of RNA polymerase
- A. Attachment of primer
- B. Opening of double helix
- C. Binding of RNA polymerase
- D. Formation of GC hair pin
Explanation
The first step of transcription is the binding of RNA polymerase by using its sigma factor with the promoter region. In the next step, the DNA duplex gets open and the process of transcription is initiated by the core RNA polymerase and it will continue adding RNA nucleotides till it encounters a stop signal.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
