Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.

Explanation:

All the three options given can cause checkpoint genes to interrupt cell division.

Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.

Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
