3a 3a) Both DNA synthesis and RNA synthesis are carried out by polymerases that catalyze theformation of these nucleic acids; however, there are some important differences between theenzymes that perform these two types of reactions and the products that result. Briefly describethree (3) differences between DNA synthesis (in the context of DNA replication) and RNA synthesis(in the context of transcription) other than the obvious fact that one uses DNA polymerases toproduce DNA from deoxyribonucleotide triphosphates and the other uses RNA polymerases toproduce RNA from ribonucleotide triphosphates.hat does not clearlyevni

DNA replication occurs in all living organisms and is essential for passing the genetic information to the future generations. It is a biological process of producing the exact replicas of DNA from original strand. Since the DNA is not the genetic code for protein synthesis, so it must be transcribed into mRNA (RNA synthesis) which can be further translated into protein (protein synthesis). Difference between the DNA synthesis (DNA replication) and RNA synthesis (transcription) are: DNA Synthesis RNA synthesis It is a duplication of a double-stranded DNA. It is a biochemical creation of a new single-stranded RNA molecule. Function An exact replica of parental DNA molecule is produced during replication. It is a process of transcribing DNA nucleotide into mRNA sequence. Enzyme It is catalyzed by DNA polymerase. Enzyme adds nucleotide to an the growing DNA strand. It is catalyzed by RNA polymerase. Occurrence DNA Replication usually take place before the RNA synthesis. Take place during S phase of the cell cycle. RNA synthesis is followed by protein synthesis. Take place during G1 and G2 phase of the cell cycle. Nucleotides Nucleotide bases used are Deoxyribonucleotide triphosphate ( A, G, T, and C) Nucleotides such as Uridine mono phosphate (UMP, CMP, AMP, GMP). Copying The entire genome of the strand is copied into new strand. Only the specific genes on the strand are copied.
