WebExamples Restriction enzyme sites. Palindromic sequences play an important role in molecular biology.Because a DNA sequence is double stranded, the base pairs are read, (not just the bases on one strand), to … WebIntroduction. Special enzymes termed restriction enzymes have been discovered in many different bacteria and other single-celled organisms. These restriction enzymes are able to scan along a length of DNA looking for a particular sequence of bases that they recognize. This recognition site or sequence is generally from 4 to 6 base pairs in length.

WebThe above figure shows the size of each of the fragments/bands produced when λ DNA is cut with each of these restriction enzymes. The sizes were determined by comparison to a molecular ladder (figure 2A) which has bands of known sizes when it is separated by electrophoresis at the same time as the digested λ DNA. Restriction sites of Lambda … WebIndividual restriction endonucleases recognize specific sequences, usually in the order of four to six bases in length, and these sequences are often palindromes, ... (Note that the antisense strand, which reads CTTAAG in the 3′ to 5′ direction, will also read GAATTC in the 5′ to 3′ direction. This is what is meant by a palindromic ...
Web常见限制性内切酶识别序列(酶切位点)（BamHI、EcoRI、HindIII、NdeI、XhoI等）在分子克隆实验中，限制性内切酶是必不可少的工具酶。无论是构建克隆载体还是表达载体，要根据载体选择合适的内切酶（当然，使用T载就不必考虑了）。先将引物设计好，然后添加酶切识别序列到引物5' 端。 WebEcoRI is a restriction endonuclease that creates cuts at specific positions within the DNA. These sites are called restriction sites. The restriction site of EcoRI enzyme is: 5'-GAATTC-3'. 3'-CTTAAG-5'. The enzyme EcoRI makes cuts within this sequence as shown in the figure.
