Q1. Prokaryotic cell E. coli consists of a single closed-circular DNA molecule of 4.6 x 106 bp long. This DNA molecule would be 1.6 mm if the double helix is relaxed. Please describe what strategies does E. coli use to pack such a long molecules into its nucleoid less than a micrometer (mm) in diameter. (20 points)

INTRODUCTION Understanding how the genetic processes of the cell work requires powerful,and complementary experimental approaches including the use of suitable model organisms in which the tools of genetic analysis are available

Z 链（Z chain） 伴胞（3 cell）：是和筛胞并列的一种细胞，是活细胞，有细胞核和浓厚的细胞质。伴胞和筛管是从分生组 织的同一母细胞分裂发育而成。二者间存在着发达的胞间连丝，在功能上也是密切相关，伴胞和筛管分子 共同完成有机物的运输。 孢子（spore）：植物营养生长到一定时期，进入生殖生长阶段，产生具有生殖功能的细胞，这些细胞不经 两性的结合可发育成新个体，这种繁殖方式称为无形繁殖。这种具有生殖功能的细胞称为孢子
