The Gene is defined as is a segment of DNA that produces a functional product. Here, the functional product is nothing, but a protein. The proteins derived from the information provided form the genes. The derived proteins are polymeric compounds have amino acids as their monomeric units.
The genes are technically or classically defined as a unit of heredity. The genes are located on chromosomes. The chromosomes are having different types of genes on them. Each gene is responsible for the production of a single protein molecule, these protein molecule are expressed as a character on an individual organism.
At the molecular level the genes are linear polymeric chains that are composed of nucleotides as their monomeric molecules. Every organism has four different types of nucleotides they are: Adenine (A), Guanine (G), Thiamine (T), and cytosine (C). These nucleotides are polymerized into DNA molecule by the process called DNA polymerization.
This long DNA molecule is have some special regions, they are:
• A promoter sequence
• Enhancer sequences
• Terminator sequence
The promoter sequence is the initial sequence that contains "consensus sequences," these sequences are never altered in any organism. During the transcription mechanism, the RNA polymerase enzyme binds on promoter sequence.
The Enhancer sequences are involved in the enhancement of the transcription process by the RNA polymerase.
The Terminator sequence is involved in the termination of the transcription process.
