These phenomena observed in Saccharomyces cerevisiae are highly conserved in eukaryotes, thus rendering yeast, which is easy to use, an essential model organism.

Pairs of allelic genes may exchange chromosomal locations( genetic elements can move, both between chromosomes and within them.) by a process known as genetic recombination.. Homologous recombination . General background to site-specific recombination . The lambda recombination system (more stealing from other organisms!). Potential advantages of using recombination for cloning. Adaptation of the lambda recombination system for efficient cloning – GATEWAY technology. the attB1 & 2 sequences are relatively short and are therefore suitable for addition to gene-specific primers . After PCR amplification, fragment contains the attB1 and attb2 sequences, and can be used for recombination with a vector carrying the attP1 and atP2 sequences, and the addition of the BP clonase enzyme mix. .
