Central dogma. Central dogma is represented by the schematic above. All cells whether prokaryotic or eukaryotic undergo this process. where does this process take place? In simple terms, what is taking place during central dogma?

The Central Dogma of Biology simply refers to the core process of the multiplication of living things at the cellular level. The Central Dogma refers to three process: 1) REPLICATION of DNA into another strand of DNA, 2) TRANSCRIPTION of DNA to form RNA, and 3) TRANSLATION of the RNA into proteins. (In the diagram you have given, it does not show the replication of DNA but simply know that this also happens.)

Almost every living thing, if not all, is made up of proteins but this protein has to come from somewhere first. This is where the dogma comes in. Cells have DNA inside that replicate in order to form new cells.  Replication happens inside the nucleus of the cell for eukaryotes; and inside the cytoplasm of the cell for prokaryotes. Another path DNA can take is the formation of RNA a.k.a transcription. There are multiple reasons why RNA has to be made first but for now it is enough to know that one difference of RNA from DNA is that RNA has the nucleoside base uracil while DNA has thymine instead of uracil.

Transcription happens in the nucleus for eukaryotes and in the cytoplasm for prokaryotes. Once RNA has been made, it is delivered out of the nucleus (for eukaryotes) and finds its way to the ribosomes in the cytoplasm (for both eu- and prokaryotes) where translation takes place.

Translation is the process of converting the RNA into proteins which can now be utilized by the cells.

The central dogma of the molecular biology explains how information from DNA is translated into proteins.

There are three distinct parts of this process.

Firstly, in the nucleus the DNA copies itself with help of different proteins in the process called replication.

In the second part, the information on the DNA is passed down to messenger RNA (mRNA) in the process called transcription. In this process, with the help of proteins, the sequence of DNA is divided into triplets and transcribed into a single mRNA strand.

When the mRNA is formed it leaves the nucleus and goes to the ribosome, where the translation, which is the third part of the central dogma happens.

In this process, the triplet code on the mRNA is translated into a sequence of amino acids with the help of the transport RNA (tRNA). Each triplet on mRNA compliments a triplet on the tRNA which transports one amino acid. When the whole sequence on the mRNA is translated into a sequence of amino acids the primary structure of a protein is formed.
