 A Cartoon Analogy of Gene Expression in Prokaryotic Cells

The above figure is explaining the analogy of protein synthesis in the cells of prokaryotes. Unlike in the eukaryotes here, both the transcription and translation occur within the cytoplasm as there is no defined nucleus.

The process of transcription needs 

1.The gene-DNA coding and noncoding strands contain the codons that represent the necessary genetic recipe to make a particular protein-This is analogous to a particular page that contains the recipe to be transcribed from a cookbook.

2.The DNA depending RNA Polymerase (RNAP) with its components- This is analogous to a copying machine fitted with its necessary parts.

3.The transcribed mRNA -The copy of the recipe ejected out by the copying machine in its copy tray-outlet.

The process of translation needs,

1.The various amino acids molecules. Unlike the eukaryotes where the first amino acid is methionine but here in prokaryotes, the first amino acid is a modified methionine (formyl methionine) -This is analogous to the raw materials to prepare a particular food.

2.The various types of tRNAs -This is analogous to various types of utensils to be used to bring different kinds of raw materials to the cooker

3.The Ribosomes-The cookers used to cook the protein

4.The protein molecule- The finished product.

The major difference from the eukaryotes is here the mRNA copied is matured and directly undergo translation without any corrections or splicings.
