Im having trouble answering this question.  What type of cells can be altered by GETs like CRISPR and what types of cells cannot and why is this so?

Please ASAP. Thank you

. All mutations that abolish function of the Rho termination protein in E. coli are conditional mutations;no cells with null mutations of the Rho-encoding genehave ever been isolated. What does this tell you aboutthe rho gene and its product?

Mutation: Thiamine Dimers A. what is a mutagen or cellular process that leads to this mutation? B. If the nucleotide excision repair pathway is not functional, is there another pathway or mechanism for preparing this mutation? if so, what is the pathway/mechanism? C. what is the consequence of this mutation if it is not repaired before DNA is replicated to make the next generation of cells?

Please help a bit confused
