Answer:

Please mark me as the brainliest

Answer 2

(a) Process of transcription in a prokaryote:

• Initiation: RNA polymerase enzyme along with initiation factor binds with DNA sequence at promotor and starts transcription.
• Elongation: RNA polymerase enzyme nucleoside triphosphate acts as a substrates and polymerises the nucleotides of templates as a complementary strand.
• Termination: Termination factor replaces the initiation factor at the termination point of DNA sequence.

(b) The two additional complexities observed in the process of transcription of    

     eukaryotes.

• In eukaryotes transcription occurs in nucleus.
• In eukaryotes RNA processing is required as its structural gene is monocistronic.
