Question

what happens in elongation of transcription ​

Answer 1

Elongation. The elongation phase of transcription refers to the process through which nucleotides are added to the growing RNA chain. As the RNA polymerase moves down the DNA template strand, the open complex bubble moves also.

Answer 2

ELONGATION

• The RNA polymerase uses ribonucleoside triphosphate as substrates and polymerase in a template dependent manner following the rule of complementarity.

• RNA polymerase moves along the transcription unit.

• It causes unwinding and opening the helix and continuous elongation of RNA.

• The ⌐ factor of the RNA polymerase separate on the initiation of RNA chain.

• The remaining part of RNA polymerase referred as core enzyme moves along the DNA template.

• It causes elongation of RNA chain at the rate of 30 nucleotides per seconds.

• Elongation takes place in 5’ – 3’ direction.
