选项
A、Proteins bound to the nucleus
B、Histones
C、Maternal messenger RNA’s
D、Cytoplasm
E、Nonbeaded intervening DNA
答案
C
解析
C is the best answer. Lines 38-41 in from us that in his study of sea urchins, Gross “found that an unfertilized egg contains substances that function as morphogetic determinants.” Lines 58-60 assert that the “substances that Gross studied are maternal messenger RNA’s,” and in lines 62-63 we learn that these maternal messenger RNA’s can be found in “ a wide variety of organisms.”
