How does replication differ from transcription

Copying It involves copying of the entire genome. It involves copying of certain individual genes only. It involves unwinding and splitting of only those genes which are to be transcribed.

Processing 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. Amy Cash. Department of Biology. Comments: Replication vs Transcription.

Uses the genes as templates to produce several functional forms of RNA. In eukaryotes complementary base pair nucleotides bond with the sense or antisense strand. Since there are 4 bases in 3-letter combinations, there are 64 possible codons 43 combinations. The first step in the process is the unwinding and separation of the two strands of the DNA helix.

The mRNA is essentially the cellular blueprint for the construction of a particular protein. It travels from the nucleus to the cytoplasm, where it is translated into protein, a process known as gene expression.

This is done in preparation for cell division, or mitosis. Before a cell divides, the DNA must be copied so that there is a copy for each of the resulting daughter cells. RNA polymerase then catalyses the formation of phosphodiester bonds between adjacent ribonucleotides. Elongation will continue until the RNA polymerase encounters a stop sequence.

In this article, we will learn both similarities and differences between replication and transcription. DNA replication and transcription are two complex biological processes and they have several differences between them. These differences between transcription and DNA replication are mentioned below:.

DNA replication. It is the process of making new copies of DNA. It is important for the regulation of the growth and division of cells. It is the method of regulating gene expression. Transfer of genetic information. Occurs during. The S phase of the cell cycle. Transcription takes place in the G1 and G2 phases of the cell cycle.

Takes place in preparation for cell division. It takes place in preparation for protein translation. Involved in. The process is involved in cell division.
