What is the difference between a constitutive gene and a regulated gene?
To review:
The differences between a regulated gene and a consecutive gene.
Introduction:
Gene regulation is a process in which, the level of gene expression maintains and varies under different conditions. Some genes are regulated at the time of gene regulation only. There are three types of a regulatory genes which are, repressor, activator, and inducer. Some genes are expressed occasionally.
Explanation of Solution
The difference between a regulated gene and consecutive gene are as follows:
Regulated gene | Constitutive gene |
These genes are expressed occasionally. | These genes are usually expressed all the time in the cell. |
The amount can vary according to the condition. | These genes are expressed at a fixed rate. |
Structure of a regulated gene is quite complicated. | The structure is simpler. |
Examples: enzymes in pancreas (insulin gene) | Examples: enzymes in glycolysis process |
Therefore, it can be concluded that there are many differences between consecutive and regulated gene. The key difference between them is, a regulated gene is expressed occasionally whereas, a consecutive gene is expressed usually, all the time in the cell.
