Ligation of DNA is a critical step in many modern molecular biology workflows. The sealing of nicks between adjacent residues of a single-strand break on a double-strand substrate and the joining of double-strand breaks are enzymatically catalyzed by DNA ligases. The formation of a phosphodiester bond between the 3' hydroxyl and 5' phosphate of adjacent DNA residues proceeds in three steps ...
Ligation (molecular biology) A sticky end ligation Ligation is the joining of two nucleotides, or two nucleic acid fragments, into a single polymeric chain through the action of an enzyme known as a ligase.
Tubal ligation, or getting your tubes tied, is a permanent way to prevent pregnancy. It involves cutting or blocking your fallopian tubes.
Tubal ligation, or getting your tubes tied, has a number of advantages and disadvantages. It's also permanent and hard to reverse, which is both an advantage and a disadvantage.

Explore the chemistry of DNA ligation, the catalytic engine (ligase), and how this fundamental process underpins modern biotechnology.
What Is DNA Ligation and How Does It Work? - Biology Insights
Ligation, the process of joining DNA fragments with a DNA ligase, proceeds in three steps. Learn more about ligation with our quick animation.
Overview Tubal ligation is a type of permanent birth control. It's also known as having your tubes tied or tubal sterilization. During this surgery, the fallopian tubes most often are cut and tied to prevent pregnancy for the rest of your life. Tubal ligation prevents an egg from moving from the ovaries and down to the uterus through the fallopian tubes. It also blocks sperm from traveling up ...
