What is mRNA processing?

, , Leave a comment

Messenger RNA or mRNA refers to molecules that help transport genetic code and information from the master molecule called DNA.  Without the mRNA, various genetic details will not be able to reach the other parts of the cell where they are needed for various processes including sequencing of amino acids or protein build-up. The sequence of activities involving the transport of genetic material from the nucleus and master DNA to other parts of the cell is called mRNA processing and all parts are essential in terms of cellular genetic development.

Protein in the form of amino acids will not be built-up and developed properly without proper mRNA processing. This important cellular activity starts with DNA replication.  The master DNA molecule is composed of 2 strands of genetic material and one copy of these strands will be created and this will be called mRNA or messenger RNA.  This special RNA molecule is called the messenger molecule because it functions to transport the DNA-copy to the site of protein build-up and synthesis.  In the case of human cells, mRNA processing dictates that genetic material from the DNA will be transported to the endoplasmic reticulum. The materials transported through mRNA processing are said to be the exact copy of the genetic content of the master DNA.  The whole coding sequence with the master DNA will end once various nucleotides will be capped and the tails will develop.  After which, the mrNA processing will continue to complete the protein build-up of cells.  Once these materials reach their destination such as the endoplasmic reticulum, protein sequencing will follow and this will contribute to the overall genetic makeup of cells.

At the endoplasmic reticulum, the actual creation of proteins will be done through the help of messenger RNAs. All mRNA’s that reach this so-called construction site will be processed again and decoded for their genetic content.  Protein build-up will then continue depending on the needs of different cells in the body.
