Scientists have suggested the existence of a hidden layer that controls the work of genes

In new study, evolutionary biologist Rama Singha hypothesizes the existence of a hidden layer

the genetic code that controlsthe interaction of genes and how their various combinations give a specific result. This layer consists mainly of as yet unexplored biochemical pathways that control gene expression in cells through chemical reactions.

Once we studied genes, we believed thatwe know everything we needed. But this is not the case. Individual genes don't tell the whole story, but how they interact may tell us more. Individual genes, as a rule, have very little influence on the final result of a particular process.

Deciphering how our genes are responsible forhaving brown eyes, thinning hair, or high cholesterol is a difficult mathematical and scientific challenge, especially if you look only at the genes themselves.

A person can contain a huge amountcombinations of genes, including previous versions that his relatives had. The body does not constantly use all of its genetic material, but cells contain backup versions of their own evolution if habitual conditions change.

Singh notes that the ability to accessprevious combinations of genes give each organism the ability to adapt and change in its environment, and biochemical pathways allow cells to extract information from this memory when needed.

It can be compared to checking and savings accounts: every day you use a checking account, but if something happens, withdraw funds from the savings account.
