Question

Inheritance of a character is also affected by the promoter and regulatory sequences of a structural gene. Hence, sometimes the regulatory sequences are loosely defined as

• A. Structural gene
• B. Regulatory gene
• C. Promoter gene
• D. None of the above

Answer 1

The correct option is B Regulatory gene

A regulatory gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences encode regulatory genes. Sometimes the regulatory sequences are loosely defined as regulatory genes because the regulatory sequences of a structural gene affect the inheritance of a character.

So, the correct answer is 'Regulatory gene'.
