有兩題還是不太會
麻煩幫忙解答一下
13.which of the following restriction enzymes when used for digesting an
E. coli genomic DNA sample can generate more DNA fragments . (the cleavage
sequence recognized by each enzyme is shown in parenthesis)
(A)Not I (GC/GGCCGC)
(B)Hind III (A/AGCTT)
(C)Hinf I (G/ANTC)
(D)Hpa I (GTT/AAC)
完全不會
31.which of the following statements is true?
(B) production of malonyl-CoA from acetyl-CoA is the controlling step in
fatty acid synthesis,this reaction has requirement for NADPH as cofactor
(C)Both phospholipids and apo C-II are required as cofactors for
lipoprotein lipase
我想知道一下(B)的錯誤是哪裡
還有(C)pospholipids不太清楚他當cofactor是做哪些作用

1F:推 demon123:this reaction has requirement for NADPH as cofactor 02/14 12:31
2F:→ demon123:cofactor是biotin 02/14 12:32
3F:推 ghostlywolf:第一題個人是寫D,因為他是blunt end,切開片段不容易 02/14 12:53
4F:→ ghostlywolf:黏回去 02/14 12:53
5F:推 demon123:我選C因為他問可以切最多的 C只認4個base 02/14 13:32
6F:→ freshjive921:第一題(C)機率學 02/15 16:49
7F:推 qqmango:第二的(B) acetyl-CoA->malonyl-CoA是用ATP來活化吧 02/16 23:52
