===============================================

37 遺傳性非息肉症大腸直腸癌(hereditary nonpolyposis colon cancer, HNPCC)病患是在何種DNA修復功能上產生缺失?

 核苷酸切除修復(nucleotide excision repair) 鹼基切除修復(base excision repair)

重組修復(recombinational repair) 核酸錯誤配對修復(mismatch repair)

ans: mismatch repair


sometimes when there are two similar answers, the right answer is not either one of them.


===================================

39 下列那一序列會調控真核mRNA進行核內polyadenylation?

UUAUUU UUUUUAU UAUUUUU AAUAAA


AAuAAA!!!!! A - poly-A-denylation

=====================================

41 下列有關eicosanoids的敘述,何者正確?

Eicosanoids是屬於autocrine的激素

Eicosanoid family中的前列腺素(prostaglandin)主要作用是促進子宮平滑肌之放鬆

Eicosanoid family中的thromboxanes主要影響血液凝集功能(blood clotting)

Eicosanoids之半生期(half-life)長達1年


answer is a or c


b is wrong because prostaglandin induce uterine contraction!


ega-6 (ω-6) EFAs. The ω-6 eicosanoids are generally pro-inflammatory; ω-3's are much less so. The amounts and balance of these fats in a person's diet will affect the body's eicosanoid-controlled functions, with effects on cardiovascular disease,triglycerides, blood pressure, and arthritis. Anti-inflammatory drugs such asaspirin and other NSAIDs act by downregulating eicosanoid synthesis.
