A gene is defined as the functional unit of inheritance.The DNA sequence coding for tRNA or rRNA molecule also define a gene.Inheritance of a character is also affected by promoter and regulatory sequences of a structural gene. Hence, sometime the regulatory sequences are loosely defined as regulatory genes, even though these sequences do not code for any RNA or protein. The DNA sequence coding for tRNA or rRNA molecule also define a gene

Molecular Basis of Inheritance, NCERT LINE BY LINE, pre-class /

What is a Gene? A gene is the functional unit of inheritance. It carries the instructions for a specific trait or function. Gene Location There is no ambiguity that genes are located on DNA. However, defining a gene based on DNA sequence alone can be complex. RNA-Coding Genes DNA segments coding for tRNA or rRNA
