Homeotic genes are regulatory genes that work after the body axes have been established.

. The lettuce leaves cells have a high salt concentration so water diffuses from the salad dressing into the leaves causing them to wilt. MRNA never enters the nucleus of the cell where our DNA genetic material is located so it cannot change or influence our genes. Our cells break down mRNA and get rid of it within a few days after vaccination.

They do not affect or interact with our DNA in any way. Positional information regulates pattern formation. The mRNA and the spike protein dont last long in the body.
