tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized ...

The end defines the means in bacterial mRNA decay
In eukaryotes, the process of mRNA decay generally involves loss of the 3′ poly(A) tail and removal of the cap by a decapping enzyme (Dcp2). The body of the mRNA is then degraded from the 5 ...

Messenger RNA (mRNA): The Cellular Messenger Delivering Genetic Instructions
Messenger RNA carries genetic information from DNA in the highly protected nucleus out to the rest of the cell, where structures called ribosomes can build proteins according to the DNA blueprint.
