Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein can be made. They published their report in Science.
The messenger RNA (mRNA)-based vaccines developed to fight the virus SARS-CoV-2 saved lives and made the nucleic acid a household name during the COVID-19 pandemic. Suddenly, everyone knew a little bit more about the molecule that helps convert genetic information into proteins.
But in addition to determining which proteins are made, mRNAs can also specify how much protein is produced.
