A form of DNA, in which the double helix is wound in a left-hand, instead of a right-hand, manner. DNA adopts the Z conformation when purines and pyrimidines alternate on each strand, e.g. 5'CGCGCGCG 3' or 3'GCGCGCGC5'. Synonym: zig-zag DNA.
A region of DNA that is "flipped" into a lefthanded helix, characterized by alternating purines and pyrimidines, and which may be the target of a DNA-binding protein.

A technique applied to a DS1 frame to ensure pulse density requirements are met, where bits 2 through 193 of each frame are scrambled to minimize the occurrence of all-zero octets. When an all-zero octet is contiguous to another octet with zeros and they would combine to violate the ones density requirement, an algorithm is invoked where some all-zero octets are replaced by an address chain. The reverse algorithms are performed by the receiving terminal.

First launched in 1999, Zeal was a volunteer-built web directory which was bought by LookSmart for $20 million in October 2000. Combining the work from LooksmartÂs paid editors with that of volunteers, they wrote profiles of websites and submitted them in relevant subcategories of the Zeal database. The directory content was downloaded and used by Looksmart and its partners including MSN, Lycos and Altavista. To become a Zeal volunteer, one needed to pass an introductory level test prior to submitting website profiles and being able to edit other peopleÂs work. As one gained more experience and kudos, an editor was able to create and maintain special categories of interests. The more experienced editors called Zealots and Expert Zealots were responsible for developing community and assist those people called "Community Members". Zeal had volunteer members from all over the world including USA, United Kingdom, Australia, India, Spain, Switzerland, Japan and New Zealand. When MSN pulled from the relationship, ZealÂs traffic had declined considerably which lead to its closure on 28th March 2006.
