Every cell in your body comes from a single cell: an egg, fertilised by a sperm. Each contains the exact same genetic blueprint for your life: your DNA.
Yet cells in your brain look and behave nothing like those in your muscle or skin.

Why? Because while each cell has the same instructions, each cell only reads certain sections â certain genes. A layer of what are called epigenetic instructions sit on top of your DNA, telling each cell which parts to read and which parts to ignore.

What will it take for Australia s borders to open?
The federal government recently extended the existing emergency period by three months until 17 June 2021, meaning international travel will remain off-limits for those who don t qualify for an exemption until the middle of the year, at the earliest.
A Department of Health spokesperson said the government s expectation is that while COVID-19 continues to pose a significant threat to public health around the world, people coming to Australia will need to undertake appropriate risk mitigations .
While that strategy includes immunisations, they said the government does not view the vaccine as a panacea or a complete substitute for other public health interventions , but rather a supplementary measure.
