It provides tools with an intuitive interface that assists you in DNA cloning, sequence analysis and visualisation.

Besides the low efficiency of cloning - just 1.7 per cent of embryos came to term - another challenge to creating transgenic dogs is controlling where in the nuclear DNA a foreign gene lands.
