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.

Q: Question: Is kREX2 essential for either procyclic or bloodstream form Trypanosoma brucei?
Answer: KREX2 is a U-specific exonuclease that is dispensable for RNA editing in vivo in T. brucei BFs and PFs. This result suggests that the U deletion activity, which is required for RNA editing, is primarily mediated in vivo by KREX1 which is normally found associated with only one type of editosome. The retention of the KREX2 gene implies a non-essential role or a role that is essential in other life cycle stages or conditions.

A: no

Q: Question: Does cSTMP induce apoptosis and mitochondrial dysfunction in human myeloma RPMI8226 cells via CHOP-dependent endoplasmic reticulum stress?
Answer: Our results indicated that CSTMP could induce apoptosis and mitochondrial dysfunction in RPMI8226 cells via CHOP-dependent ER stress.

A: yes

Q: Question: Does traumatic brain injury induce neuroinflammation and neuronal degeneration that is associated with escalated alcohol self-administration in rats?
Answer: These results show an association between post-TBI escalation of alcohol drinking and marked localized neuroinflammation at the site of injury. Moreover, these results highlight the relevance of baseline alcohol preference in determining post-TBI alcohol drinking. Further investigation to determine the contribution of neuroinflammation to increased alcohol drinking post-TBI is warranted.

A:
yes
