Research led by Prof Frank Gannon has uncovered new revelations on possible ways to switch genes on and off and how cells interpret their DNA.
Only some genes are expressed in any given tissue. Proteins active in nerve cells are not expressed in the liver. How this is controlled is complex. One fundamental factor is whether the DNA is tagged or modified (methylated) in the region of a gene. This is important in gene expression and balancing the level proteins in different cell lines.
Although gene methylation (when a gene is turned on or turned off) was thought to be stable and unchangeable, this is not the case. Things are even more complicated than previously thought. Transient, cyclical and dynamic methylation is a general phenomenon occurring at many different genes and in many different cell types.
Yet another unexpected level of complexity needing a “just so story” from Darwinian devotees. The obvious Design is only an illusion!
