Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Is there substantial nuclear and cellular disintegration before detectable phosphatidylserine exposure during the camptothecin-induced apoptosis of HL-60 cells?
Answer: During CAM-induced apoptosis of HL-60 cells, the external exposure of PS can either precede or follow DNA cleavage, which suggests that PS exposure is not always an indicator of early apoptosis.
Output:
yes
