Which statement is incorrect about CRISPR?

#SCPH01 Biochemistry

It was first identified as an adaptive immunity pathway in prokaryotes providing resistance to bacteriophage and analogous to the RNA interference process found in eukaryotes.
It does not utilize double-stranded sequence-specific breaks and does not repair using HDR via homologous recombination.
The system consists of two parts, a short synthetic guide RNA ( gRNA) and a nonspecific double-stranded endonuclease termed Cas9.
It is also possible to program Cas9 with multiple guide RNAs to allow multiplex site-specific editing for designing large deletions, inversions and translocations.

#SCPH06 I Botany

Programmed cell death, or apoptosis, is an essential part of animal development. In the nematode, with its invariant cell lineage, particular cell lineages or particular cells within specific lineages are destined to end in programmed cell death, and it was this feature that allowed the identification of the process and the analysis of its genetic control.
