Question
Match the following regarding transcription:
 
p. Initiationi. Ribonucleotides arepolymerised according to the codeq. Elongationii. RNA polymerase binds to TATA boxr. Terminationiii. mRNA is bound by protective moleculess. Cappingiv. RNA polymerase detaches from DNA
Options:
A .  p-i, q-ii, r-iii, s-iv
B .  p-ii, q-iii, r-iv, s-i
C .  p-ii, q-i, r-iv, s-iii
D .  p-iv, q-iii, r-ii, s-i
Answer: Option C
:
C
Transcription takes place in three major steps- initiation, elongation and termination. Initiation involves binding of RNA polymerase to the TATA box. This is followed by addition or polymerisation of ribonucleotides according to the template. The last step is termination, during which RNA polymerase detaches from the parental DNA in order to end the transcription process. The newly formed mRNA then undergoes processing, which involves capping and tailing by protective molecules.
