Proposed model changes
Purpose: the technology of engineering mutations and gene replacement has been developed in C. elegans. With these new research tools, capture and display of the molecular information of these alleles needs to be updated. We propose a new class, Construct, to capture the specifics of the DNA tool used to perform the replacement or engineering, while the Variation model gets updated to record the engineering event itself and its impact on the genome. As a side benefit to the creation of the Construct model, we can use this new class to also capture the genomic arrays used create transgenes.

WBPaper00045772 Paix et al., 2014
Discusses Homology directed repair (HDR) vs Nonhomologous end-joining (NHEJ). It would seem that distinguishing the method used to create engineered alleles is important. However, the tags should perhaps be modified to distinguish double stranded break method and repair method.
