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 nucleotide 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 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,
