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: Consider Input: Question: Does pINK1 trigger autocatalytic activation of Parkin to specify cell fate decisions?
Answer: Autocatalytic activation of Parkin bolsters its accumulation on mitochondria and apoptotic response to valinomycin. Our results suggest that PINK1-Parkin constitutes adamage-gated molecular switch that governs cellular-context-specific cell fate decisions in response to variable stress stimuli.

Output: yes

Input: Consider Input: Question: Does helicobacter pylori infection in Mongolian gerbils initiate hematological diseases?
Answer: A single H. pylori infection is insufficient to cause onset of ITP or IDA and other factors may be required for disease onset.

Output: no

Input: Consider Input: Question: Does the search for DNA homology limit stable homologous pairing promoted by RecA protein?
Answer: We conclude that, during the formation of synaptic complexes by RecA, the search for homology is not rate-limiting, and that the iteration frequency of the search is around 10(2)-10(3) s-1. This value agrees well with what has been calculated as the minimum number for such a frequency in genome-wide searches, and limits the possible structures involved in the search for homology to those involving very soft (low energy) interactions. Furthermore, from the order of the reaction at the DNA concentrations found in eukaryotic nuclei, and the rate constant of the overall reaction, we predict that the search for homology is also not the rate-limiting step in the genome-wide searches implicated in meiosis and in gene targeting.
Output: no
