Summary Introduction

To compare:

The gene regulation in prokaryotes with the gene regulation in eukaryotes.

Given:

Regulation of gene expression includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA).

Introduction:

Gene expression can be characterized as the procedure by which the information encoded in a gene is utilized to coordinate the assembly of protein molecule. Gene expression is explored via a study of the protein function and structure, translation and transcription, stem cells and differentiated cells.

These products are often proteins, but in non-protein coding genes such as ribosomal RNA (rRNA), transfer RNA (tRNA) or small nuclear RNA (snRNA) genes, the product is a functional RNA. The process of gene expression is used by all known life - eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea).
