Q: 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.
Question: Does ara-C affect formation of cancer cell DNA synthesome replication intermediates?
Answer: Our results indicate that ara-C's action on DNA replication is mediated primarily through DNA polymerase alpha and suggest that this enzyme plays a key role in DNA synthetic initiation events. The results also provide definitive support for the use of the DNA synthesome as a unique and powerful model for analyzing the mechanism of action of anticancer drugs which directly affect DNA replication.
A:
yes
