Epigenetic silencing is a barrier to editing the X chromosome using the SEC-based CRISPR/Cas9 knock-in protocol in C. elegans
{{output}}
Self-excising-cassette (SEC)-based CRISPR/Cas9 knock-in is widely used for generating endogenous fluorescent protein tags in C. elegans . Here, we report a lack of success targeting the X chromosome using this method. CRISPR/Cas9 works as intended, but subsequ... ...
