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: Does expression of the pair-rule gene homologs runt , Pax3/7 , even-skipped-1 and even-skipped-2 during larval and juvenile development of the polychaete annelid Capitella teleta support a role in segmentation?
Answer: C. teleta eve, Pax3/7 and runt homologs all have distinct expression patterns and share expression domains with homologs from other bilaterians. None of the pair-rule orthologs examined in C. teleta exhibit segmental or pair-rule stripes of expression in the ectoderm or mesoderm, consistent with an independent origin of segmentation between annelids and arthropods.
[A]: no


[Q]: Question: Does production of infectious human immunodeficiency virus type 1 require depletion of APOBEC3G from virus-producing cells?
Answer: Our results suggest that Vif and APOBEC3G can be efficiently co-expressed. Thus, depletion of APOBEC3G from Vif expressing cells as suggested previously is not a universal property of Vif and thus is not imperative for the production of infectious virions.
[A]: no


[Q]: Question: Does sildenafil treatment attenuate ventricular remodeling in an experimental model of aortic regurgitation?
Answer: Sildenafil slightly inhibits LV remodeling and improves fractional shortening in rats with AR when treatment is initiated early.
[A]:
yes
