[Structural analysis of human genome by YAC technologies]

[Article in Japanese]
E Soeda. Nihon Rinsho. 1993 Sep.

Abstract

A method for construction of YAC (Yeast Artificial Chromosome) libraries with large inserts has been developed and promoted the ongoing project of human genome. Isolation by PCR screening charges the YAC clone with a unique tag of a pair of PCR primers at the defined chromosome site (Sequence Tagged Sites; STS). Current evaluation of YAC has revealed that larger YAC has more problems where rearrangements including deletion and chimera occur extensively in DNA molecules, presenting a limited use of this technology in mapping; the contig map with mega YACs will be substituted by some other system such as cosmids with which the human healthy and disease genes will be characterized.
