||DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix.
||Transcription is the process of synthesis of RNA using DNA as a template.
||To conserve the entire genome for next generation.
||To make RNA copies of individual genes.
||DNA Helicase, DNA Polymerase
||Transcriptase (type of DNA Helicase), RNA polymerase
||Occurs in the S phase of cell cycle.
||Occurs in the G1 and G2 phases of cell cycle.
||dATP, dGTP, dTTP and dCTP serve as raw materials.
||ATP, UTP, GTP and CTP serve as raw materials.
||Occurs along the strands of DNA.
||Occurs along one strand of DNA.
||Occurs in preparation for cell division.
||Occurs in preparation for protein translation.
||Replicated DNA strand remains hydrogen bonded to its template DNA strand.
||Transcribed RNA strand separates from its DNA template strand.
||It require RNA primer to start replication.
||No primer is required to start.
||Two Daughter Strands
||mRNA, tRNA, rRNA and non-coding RNA( like microRNA)
||Products remain within nucleus.
||Greater part of the product passes from nucleus into the cytoplasm.
||Products are not degraded.
||Products are degraded after their function of over.
||It involves copying of the entire genome.
||It involves copying of certain individual genes only.
||Unwinding and Splitting
||It involves unwinding and splitting of the entire DNA molecule.
||It involves unwinding and splitting of only those genes which are to be transcribed.
||It produces normal DNA molecules that do not need any processing.
||It produces primary RNA transcript molecule which needs processing to acquire final form and size.
