DNA Replication vs. Transcription

Difference Between DNA Replication and Transcription

The foundation of every living organism is DNA. This is the key to existence of how well a life goes on. Children perform in a way that some features are modeled from parents, and some are magic. This is true with DNA replication and transcription, a process that only genetic code could play.

Prokaryotes and eukaryotes have one or more polymer molecule of DNA that is a copy made for the action process of copying to occur. The positive aspect of the process of DNA replication or rather DNA synthesis is dependent on how the action proceeds to copy. Eukaryotes are a group of organisms that have cells containing a nucleus. In these organizations, the basic structure has two son of DNA which consists of nucleotide units. DNA consists of two anti-parallel strands arranged into a double helical structure. DNA replication facilitates the separation of the two strands so that the double helix opens up and copies itself in the offspring DNA. The end result is two new DNA molecules. Cell division occurs then. When the daughter cell is produced, a copy of the parental DNA is found in its nucleus. The son should be copied free of errors and transmit the information of parental cells to daughter cells.

There are three models in which a DNA copy. The semi-conservative, which is proven to be true among the three models, is where two new molecules are formed as a complex of an old thread with parental daughter. The conservative model is where the parental lines remained together for a new DNA double helix the two daughters’ son has been formed. In dispersive, two double DNA chains were created, each with the parts of molecules daughter and parent. DNA replicates at a speed of 50 nucleotides per second, per replication fork in case of humans. It can be copied to a few hours, because of the many sites of initiation of replication forks.

The transcript is similar to replication, but with different type of proteins involved. Simple, RNA blocked the same way (transfer RNA (tRNA), Ribosomal RNA (rRNA) and messenger RNA (mRNA)) in the transcript, have developed a DNA fraction double-locked. It is then followed by a step of translation, with the production of a protein molecule as the final result. The DNA serves as a template, with only a wire for the synthesis of RNA and only a small portion survives processing of RNA. The other thread is the thread of non-critical code. Genetic information is transcribed from DNA to RNA by RNA polymerase enzyme. Transcription occurs in the nucleus.

Summary:

1. Replication is the act of copying DNA of two sons. Transcription is the formation of single RNA, DNA identical two-blocked.

2. The proteins that assist in replication and transcription are different.

3. Replication results in the formation of two daughter strands, while in the transcript; the end result is a protein molecule.

4. In transcription, DNA is the template for the synthesis of RNA.
