1、Promoter prokaryote and eukaryote promoter,08 生物技术本2班 冯龙伟,Double chain DNA,1. A chain as a sense or coding chain，The RNA sequence is righteous chain deoxynucleotide sequences directly copy（T-U）2. Another chain for the antisense strand or template strand，As the RNA synthesis process of ribose nucleot

2、ide base pairing template,Prokaryotic promoter characteristics,1. Gene upstream have two conserved regions，Prokaryotes conserved sequence position-10 and -352.-10Sequences are called for Pribown框 Nucleotide sequence TATAAT -35Sequences are called for TTGACA,Eukaryotic promoter characteristics,1. In

3、the upstream there are two conserved regions，Eukaryotic conservative sequence-25和-752.-25Sequences are called for TATA框， Nucleotide sequence TATAAA -75Sequences are called for CAAT框， Nucleotide sequence GGXCAATCT,Different promoter region functions,1.-35（-75）Sequence composition reinforced with polymerase ,Factor mutual recognition and interaction Identification Zone2.-10（-25）Sequence for DNA solution spinning is very important,祝大家在一个月后的今天能够实现自己的考研梦，也希望咱们班的同学能够坚持走完自己的考研路，无论成功与否，我们曾经奋斗过,
