Web16 de ago. de 2024 · Background: Plant tissues are composed of cells that all contain the same genomic information and yet have very different properties. This occurs because cells selectively turn genes on or off during growth and in response to the environment. Which genes are active and which are silent depends on chemical modifications in the genome … WebGenes are "on" during demethylation and "off" during methylation. Histone modifications are another example of an epigenetic change. Depending on how close the histones are packed, it determines whether the gene is "off" or "on". Tightly packed histones prevent proteins from binding to the DNA, so it keeps the gene inactivated.
