NULL MUTANT Meaning and
Definition
-
A null mutant refers to a mutation that completely disrupts the function or expression of a specific gene, rendering it non-functional or inactive. It is a term used in genetics to describe an organism or cell line that carries a mutation resulting in a complete loss or absence of the function normally associated with the particular gene in question.
Null mutants can be created through various genetic techniques, such as targeted gene disruption, gene knockout, or gene deletion. These techniques aim to delete or modify specific regions of the gene sequence so that it cannot produce a functional gene product, such as a protein or an RNA molecule.
The term "null" is derived from the Latin word "nullus," meaning "zero" or "none," indicating the complete absence of the gene's normal function. Null mutants are often used in scientific research to study the effects of specific genes on an organism's phenotype or behavior. By comparing the behavior or characteristics of null mutants with those of normal organisms, scientists can gain valuable insights into the role and function of the gene under investigation.
In summary, a null mutant is an organism or cell line that possesses a genetic mutation resulting in the total loss or inactivity of a particular gene, leading to the absence of its normal function or expression.

Etymology of NULL MUTANT
The word "null" in the context of genetics and mutation has its origins in Latin. "Nullus" in Latin means "none" or "zero". In genetics, a null mutation refers to a mutation in a gene that completely disrupts its function, resulting in a loss of gene expression or production of a non-functional protein. The term "null mutant" was coined to describe an organism or individual carrying such a mutation.
