The correct Answer is:
To solve the question regarding the DNA base pair sequences that are the same when read forward or backward from a central axis of symmetry, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for a specific term that describes DNA sequences which read the same in both directions. This is a characteristic of certain sequences in molecular biology. 2. **Identifying Key Terms**: The key term here is "central axis of symmetry." This implies that the sequence has a symmetrical property, meaning it can be read in reverse and still yield the same sequence. 3. **Considering Options**: The options provided are: - Nucleases - Palindromic sequences - Termination sequences - Amino acids 4. **Analyzing Each Option**: - **Nucleases**: These are enzymes that cut DNA or RNA, not related to the sequence symmetry. - **Palindromic sequences**: These are sequences that read the same forwards and backwards, which fits the description given in the question. - **Termination sequences**: These are sequences that signal the end of transcription; they do not have the symmetry property. - **Amino acids**: These are the building blocks of proteins and are not related to DNA base pair sequences. 5. **Conclusion**: Based on the analysis, the correct answer is **palindromic sequences**. This is because palindromic sequences are defined as sequences that are identical when read from either direction. ### Final Answer: The DNA base pair sequences that are the same when read forward or backward from a central axis of symmetry are called **palindromic sequences**. ---
