Transcription procedure and the replication procedures

Question

Write down the similarities and differentiations between the transcription procedure and the replication procedures?

Answer 1

The DNA polynucleotide chain serves as the template in the replication (or DNA duplication) and along with in transcription (or RNA formation). In both procedures the pairing of two polynucleotide chains of original DNA molecule is broken through breaking of hydrogen bonds for chains to be exposed as templates. The reaction is catalyzed through specific enzymes in transcription as well as in replication.

In the replication the enzyme DNA polymerase catalyzes formation of a new polynucleotide chain using free nucleotides in putting and solution them in new chain according to DNA template exposed and to rule C-G, A-T. In transcription an enzyme RNA polymerase creates a new polynucletide chain according to DNA template exposed obeying, but, rule A-U, C-G.

In the replication original template DNA chain is kept bound by the hydrogen bonds to new formed DNA chain and a newly form DNA molecule is then generated. In transcription involvement between the template DNA chain and the new formed RNA is uncompleted and RNA constituted of only one polynucleotide chain is released.
