The correct Answer is:
To solve the question "The genes which regulate the expression of other genes are," we need to analyze the options provided and identify the correct type of gene. Here’s a step-by-step solution: ### Step 1: Understand the Options We have four types of genes to consider: 1. **Constitutive Genes**: These are genes that are always expressed and are not regulated. They are responsible for maintaining basic cellular functions. 2. **Regulated Genes**: These genes are expressed only under certain conditions and can be turned on or off. 3. **Regulator Genes**: These genes produce products (like proteins) that can influence the expression of other genes. They play a crucial role in gene regulation. 4. **Operator Genes**: These are sequences in DNA that allow regulatory proteins to bind and control the transcription of adjacent genes. ### Step 2: Analyze Each Option - **Constitutive Genes**: Since they are always active, they do not regulate other genes. - **Regulated Genes**: While they can be turned on or off, they do not inherently regulate other genes. - **Regulator Genes**: These genes specifically control the expression of one or more other genes, making them the primary candidates for the answer. - **Operator Genes**: They assist in the binding of regulatory proteins but are not genes themselves that regulate expression. ### Step 3: Identify the Correct Answer Based on the analysis, the correct answer is **Regulator Genes**. These genes are responsible for regulating the expression of other genes. ### Final Answer The genes which regulate the expression of other genes are **Regulator Genes**. ---
