In the case of mRNA vaccines against Covid-19, these are not made in the nucleus, rather they are injected into the arm to tell muscle cells how to make part of the viral “Spike” or “S ...

In contrast, despite being prone to hydrolysis, mRNA appeared to be more tractable because the nucleic acid did not need to be delivered into the nucleus; it is functional in the cytosol.

The mRNA metabolism passively shapes the levels of an mRNA modification called m6A within a steady-state cell and upon stress.

Normally, mRNA is produced in the nucleus in a process called transcription, but in the case of mRNA vaccines, it enters cells within a lipid-based protective bubble.

The Centers for Disease Control and Prevention (CDC) says on its website that mRNA vaccines that are rolling out don't "interact with our DNA in any way," and "mRNA never enters the nucleus of the ...

The mRNA in the vaccine is soon destroyed by the cell – just as any other mRNA would be. The mRNA cannot get into the cell nucleus and it cannot affect a person’s DNA. Advertisement ...

An mRNA vaccine has certain advantages over a DNA vaccine, which has to use a re-engineered virus or other delivery mechanism to make it through the membrane that protects the nucleus of a cell ...

Moderna, which has developed one of the mRNA COVID-19 vaccines used across the world, explained in a fact sheet that mRNA and gene therapy take “fundamentally different” approaches.

In the spotlight for its role in COVID-19 vaccines – and a Nobel Prize – mRNA is not a new invention. It’s a crucial messenger molecule at work every day in every cell in your body.
