Transcription and translation are two processes involved during protein synthesis. With these two processes, cells are able to make proteins. However, the process of transcription comes before translation. Transcription refers to the process of copying the DNA of a gene and using it as a template in order to make an RNA molecule.

This automatically transfers the genetic information in DNA to the newly formed RNA molecule (mRNA). It is important to know that the process of transcription occurs in the nucleus. Also, the three steps of transcription are initiation, elongation, and termination. After the formation of the RNA molecule (mRNA), it leaves the nucleus and binds with a ribosome in the cytoplasm.

Once this happens, the ribosome can read the genetic information of the mRNA. This process allows the ribosome to produce a protein by translating messenger RNA. In other words, the process of translation allows cells to produce proteins.

Transcription occurs first before translation. If in case you are not familiar with these processes, you should know that transcription is the first step that happens before the DNA-based gene expression. The information that is available on the strand of DNA gets copied into the RNA.

The mRNA copies of the gene are used as the blueprints for protein synthesis during the process of translation. Translation refers to the creation of proteins from the mRNA template. The ribosomes are located in the cytoplasm and the endoplasmic reticulum. The process of transcription also occurs in the nucleus of the cells. The process of transcription and translation is also known as gene expression.

Transcription occurs before translation. Transcription and translation are two processes related to biology. Both of these are steps that deal with DNA gene expression. Transcription is a process that involves a DNA sequence being copied by the RNA polymerase. This results in a matching RNA strand being created.

Translation is the next process and it involves the mRNA, which is the messenger rNA, being translated so that it can synthesize polypeptides and proteins. Without the instructions from transcription, the proteins would not be able to be synthesized. For this to happen, there are four steps of translation, which are activation, initiation, elongation, and termination.

Transcription and translation are two steps of DNA gene expression. Between the two, transcription will occur first. This step involved RNA being created from DNA. When this occurs, the sequence of DNA is copied by RNA polymerase, which is a special enzyme. The result of this process is a matching RNA strand. The next step is translation.

There are four steps of translation, which include activation, initiation, elongation, and termination. These steps result in the mRNA sequence making a polypeptide. Depending on the part of the cell, the act of translation can differ. For eukaryotes, translation occurs on the ribosomes. In bacteria, translation happens in the cytoplasm

Transcription is the first stage in gene communication. The translation is the second and last step of gene expression. Transcription is when genetic information on a DNA strand is shifted into an RNA strand by a series of polymerization outcomes catalyzed by enzymes called DNA defendant RNA polymerases.

The translation is the procedure of protein synthesis where the information on RNA is a protein synthesis where the information on RNA is conveyed in the form of polypeptide chains. The raw material in transcription includes parts of RNA: adenine, guanine, uracil, and cytosine.

The amino acids are the meat of translation. The identification of specific DNA sequences termed promoter cycles introduces transcription that denotes the beginning of the gene.

Transcription and then Translation

Transcription is when a DNA template has its information copied onto a messenger RNA (mRNA) and translation is when the mRNA translates its information to synthesize proteins and polypeptides. So you cant synthesize proteins if you dont have the instructions, which is what Transcription does.
