有两题还是不太会
麻烦帮忙解答一下
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)
完全不会
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

我想知道一下(B)的错误是哪里
还有(C)pospholipids不太清楚他当cofactor是做哪些作用
