Ligation (molecular biology) - Wikipedia
Ligation involves joining up the ends of a DNA with other ends, however, each DNA fragment has two ends, and if the ends are compatible, a DNA molecule can circularize by joining its own ends. At high DNA concentration, there is a greater chance of one end of a DNA molecule meeting the end of another DNA, thereby forming intermolecular ligation.
DNA Ligation Overview: Mechanism, Types, Applications
DNA ligation is the process of joining two strands or fragments of DNA molecules through a phosphodiester bond formed by the enzyme DNA ligase. DNA ligase is involved in maintaining the structural integrity of genomes by participating in DNA replication or repair processes.
DNA连接酶 - 百度百科
DNA连接酶（DNA Ligase）也称DNA黏合酶，在分子生物学中扮演一个既特殊又关键的角色，那就是连接DNA链一个碱基3‘-OH末端和它相邻碱基的5’-P末端，使二者生成磷酸二酯键，从而把两个相邻的碱基连接起来。
DNA Ligase – Structure, Types, Mechanism, Functions
2024年10月24日 · DNA ligation reactions are fundamental processes in molecular biology, enabling the joining of DNA fragments to form recombinant DNA molecules. These reactions utilize specific ends created by restriction enzymes, leading to two primary types of ligation: blunt-end ligation and sticky-end ligation.
DNA ligase - Wikipedia
DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.
DNA Ligase- Definition, Structure, Types, Functions - Microbe Notes
2023年8月3日 · DNA ligase forms a bond between the sugar-phosphate backbone to fully repair the DNA. DNA ligase plays a vital role in DNA replication, DNA repair, and DNA recombination. Now day purified DNA ligase is isolated in the laboratory, which is used in gene cloning to join DNA molecules together to form recombinant DNA.

2013年8月27日 · 利用T4 DNA连接酶进行目的DNA和载体的体外连接反应，也就是在双链DNA 5’磷酸和相邻的3’羟基之间形成新的共价键。 如载体的两条链都带有5’磷酸 (未脱磷)，可形成4个新的磷酸二酯键;如载体DNA已脱磷，则只能形成2个新的磷酸二酯键，此时产生的 重组 DNA带有两个单链缺口，在导入感受态细胞后可被修复。 1、不对称粘性末端：两种限制酶消化后，需纯化载体以提高连接效率;载体与外源DNA连接处的限制酶切位点常可保留;非 重组 克隆的背景较低; …
What is DNA ligase? | IDT - Integrated DNA Technologies
2023年9月6日 · DNA ligase is an enzyme that catalyzes the formation of a covalent bond between a 5’ phosphate and a 3’ hydroxyl group at the termini of DNA fragments; this bond ligates the two DNA fragments together. Within cells, these enzymes are essential as they are required for repairing, replicating, and recombining DNA [1].
