AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the term that describes the doubling of chromosomes. This involves identifying the correct biological process among the given options. 2. **Analyzing the Options**: - **Polyteny**: This refers to a condition where there is repeated replication of DNA without separation of the replicated chromosomes. This means that while the DNA is duplicated, the chromosomes do not separate into individual entities. Therefore, this option does not represent true doubling of chromosomes. - **Transcription**: This is the process of synthesizing RNA from a DNA template. It does not involve the doubling of chromosomes, as it is related to gene expression rather than chromosome replication. Thus, this option is incorrect. - **Duplication**: This term refers to the process where chromosomes are replicated and then separated, effectively doubling the chromosome number. This is the correct answer as it directly relates to the doubling of chromosomes. - **Translation**: This is the process of synthesizing proteins from mRNA. Like transcription, it does not involve the doubling of chromosomes. Therefore, this option is also incorrect. 3. **Conclusion**: After analyzing all the options, the correct answer to the question "Doubling of chromosomes is" is **duplication**. **Final Answer**: Doubling of chromosomes is called **duplication**. ---
