| manubriosternal junction | The angle between the manubrium and the body of the sternum at the manubriosternal junction.

| sclerocorneal junction | The margin of the cornea overlapped by the sclera. Synonym: limbus corneae, corneal margin, sclerocorneal junction. (05 Mar 2000) |
| Holliday junction | <molecular biology> A structure which occurs during homologous recombination between homologous chromosomes. While the two chromosomes are side by side, one strand of DNA on each chromosome is broken and then attached to the broken strand of DNA on the other chromosome. The crossover point, which is called the Holliday junction, is able to slide up and down between the two chromosomes, so that a little or a lot of DNA can ultimately be switched between them.
