What Does MRNA Do?


Quick Answer

During the transcription of genetic data to new cells, DNA is encoded to mRNA, also known as messenger RNA. The mRNA is then prepared to create a new DNA molecule through genetic codes established by amino acids.

Full Answer

The transfer of genetic data by mRNA during cell reproduction occurs in two stages: transcription and translation. Genes are expressed in new cells through codons, which are strands of nucleotides that create specific codes for how amino acids are arranged. During translation, several types of RNA begin the process of arranging the codons into the proper sequences necessary to create proteins important to cell functions. Once the proper sequence of amino acids has been arranged, the translation phase ends.
