STRUCTURAL GENES Meaning and
Definition
-
Structural genes refer to a specific class of genes that encode for proteins, which are the fundamental building blocks of cells and perform various essential functions within organisms. These genes provide instructions for the synthesis of proteins that contribute to the structural framework and physical properties of an organism.
Structural genes are transcribed into messenger RNA (mRNA) during a process known as transcription. The mRNA molecules are then translated into proteins during the process of translation. The proteins encoded by structural genes participate in various biological processes, such as the formation of tissues, organs, cells, enzymes, hormones, and other vital components of living organisms.
These genes are typically part of the core genome and are expressed in most cells of an organism. They often produce stable proteins that are required for the normal growth, development, and functioning of an organism. Examples of structural genes include those encoding structural proteins, such as collagens in connective tissues, keratins in skin and hair, hemoglobin in red blood cells, and actin and myosin in muscle tissues.
Mutations in structural genes can lead to various genetic disorders or diseases, as they can disrupt the structure or function of the encoded proteins. Structural gene mutations are often inherited and can result in conditions like muscular dystrophy, sickle cell anemia, or collagen-related disorders.
Overall, structural genes are integral components of an organism's genetic makeup, playing a crucial role in determining and maintaining its physical characteristics and overall functionality.

Etymology of STRUCTURAL GENES
The word "structural genes" is a term used in genetics to describe genes that are involved in producing proteins that serve a specific structural function within an organism. The etymology of the term can be broken down as follows:
1. Structural: The word "structural" comes from the Latin word "structura", which means "a fitting together" or "arrangement". It is derived from the verb "struere", which means "to build" or "to pile up". In the context of genetics, "structural" refers to genes that determine the structure or form of a particular protein molecule.
2. Genes: The word "gene" comes from the Greek word "genos" or "genesis", which means "origin" or "birth". It was first introduced by Danish botanist and geneticist Wilhelm Johannsen in the early 20th century.
