TLDR
By offering a tenfold increase in the size of the DNA molecules that can be cloned into a microbial host, this system addresses a major gap in existing experimental methods for analyzing complex DNA sources.
Abstract
Fragments of exogenous DNA that range in size up to several hundred kilobase pairs have been cloned into yeast by ligating them to vector sequences that allow their propagation as linear artificial chromosomes. Individual clones of yeast and human DNA that have been analyzed by pulsed-field gel electrophoresis appear to represent faithful replicas of the source DNA. The efficiency with which clones can be generated is high enough to allow the construction of comprehensive libraries from the genomes of higher organisms. By offering a tenfold increase in the size of the DNA molecules that can be cloned into a microbial host, this system addresses a major gap in existing experimental methods for analyzing complex DNA sources.

Identification of the cystic fibrosis gene: Chromosome walking and jumping

TL;DR: Several transcribed sequences and conserved segments were identified in this cloned region and one corresponds to the cystic fibrosis gene and spans approximately 250,000 base pairs of genomic DNA.

Human antibodies derived from immunized xenomice

TL;DR: In this paper, a transgenic animal has been modified to produce antibodies in response to antigenic challenge, but whose endogenous loci have been disabled, and various subsequent manipulations can be performed to obtain either antibodies per se or analogs thereof.

A highly conserved repetitive DNA sequence, (TTAGGG)n, present at the telomeres of human chromosomes.

TL;DR: A highly conserved repetitive DNA sequence, (TTAGGG)n, has been isolated from a human recombinant repetitive DNA library and its similarity to functional telomeres isolated from lower eukaryotes suggest that this sequence is a functional human telomere.

Genomic sequencing

TL;DR: The genomic sequencing procedures are applicable to the analysis of genetic polymorphisms, DNA methylation at deoxycytidines, and nucleic acid-protein interactions at single nucleotide resolution.

Somatic generation of antibody diversity

TL;DR: In the genome of a germ-line cell, the genetic information for an immunoglobulin polypeptide chain is contained in multiple gene segments scattered along a chromosome which are assembled by recombination which leads to the formation of a complete gene.

Separation of yeast chromosome-sized DNAs by pulsed field gradient gel electrophoresis

TL;DR: This pulsed field gradient gel electrophoresis fractionates intact S. cerevisiae chromosomal DNA, producing a molecular karyotype that greatly facilitates the assignment of genes to yeast chromosomes.

Transformation of yeast

TL;DR: This work has used recently developed hybridization and restriction endonuclease mapping techniques to demonstrate directly the presence of the transforming DNA in the yeast genome and also to determine the arrangement of the sequences that were introduced.
