DNA ligase is an enzyme that creates phosphodiester bonds to join complementary DNA strands. It occurs naturally in the body. Scientists use DNA ligase to engineer recombinant DNA. More »

DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connec... More »

One way to make the complicated details of DNA structure and function intelligible for children is to compare it to a recipe book. DNA is the master molecule that contains coded instructions for "cooking" the proteins us... More »
