Ping and others have similarly found such essential genes in bacteria or in mice.

Here we developed an approach to identify the «essential lethality» arose from these mutated / deleted essential genes, which are largely tolerated in cancer cells due to genetic redundancy.

In contrast, essential genes whose defects often lead to lethality in utero or in early extrauterine life tend to encode hubs and to occupy a central position in the network (4).

Since CNVs occur with equal frequency across the human population — we all have them, but in most of us the missing or extra genetic material doesn't hit essential genes or contribute to illness — the fact that they are seen four times as often in affected children as in their unaffected siblings points to their likely contributory role in the illness.

Biologists have uncovered how a family of essential genes interacts could offer clues about how new types of cells come to evolve.

U. urealyticum has six closely related iron transporters, which apparently arose through gene duplication, suggesting that it has a kind of respiration system not present in other small genome bacteria The genome is only 25.5 % G+C in nucleotide content, and the G+C content of individual genes may predict how essential those genes are to ureaplasma survival.

Pol III is pretty complicated — it is made up of 17 different subunits encoded by 17 different essential genes.

Overlap — Finally, successful drug targets significantly overlap with disease genes — those in which a mutation can cause a specific disease, such as cystic fibrosis — and with essential genes, that are required for normal development.

This means that these essential genes are regulated by two epigenetic layers.

This process highlighted DNA sequences that do not encode proteins but that are still needed because they direct the expression of essential genes, as well as pairs of genes that perform the same essential task — when such genes are deleted one at a time, both mistakenly seem to be dispensable.
