- Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. - Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. Eac...


The mRNA in cells relays instructions from the DNA inside the cell nucleus to tiny organelles in the cytoplasm called ribosomes. Ribosomes read the instructions and produce the proteins the cell needs. DNA is the mastermind of the cell, regulating all functions within it. It does so via instructions called codons.


While mRNA contains the "message" as to how to sequence amino acids into a chain, tRNA is the actual translator. Translation of the language of RNA into the language of protein is possible, because there are many forms of tRNA, each representing an amino acid (protein building block) and able to link with an RNA codon.


The function of tRNA is to decode an mRNA sequence into a protein and transfer that protein to the ribosomes where DNA is replicated. The tRNA decides what amino acid is needed according to the codon from the mRNA molecule.


Proteins within a cell have many functions, including building cellular structures and serving as enzyme catalysts for cellular chemical reactions that give cells their specific characteristics. The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).


Ribonucleic acid (RNA) is one of two key nucleic acids, the other being DNA. Messenger RNA (mRNA) is transcribed from DNA in the nucleus before heading into the cytoplasm and attaching itself to ribosomes to take part in translation, which is the synthesis of proteins from amino acids.


A microRNA (abbreviated miRNA) is a small non-coding RNA molecule (containing about 22 nucleotides) found in plants, animals and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression. miRNAs function via base-pairing with complementary sequences within mRNA molecules.


Pre-mRNA Splicing. Eukaryotic genes are composed of exons, which correspond to protein-coding sequences (ex-on signifies that they are expressed), and intervening sequences called introns (int-ron denotes their intervening role), which may be involved in gene regulation, but are removed from the pre-mRNA during processing.Intron sequences in mRNA do not encode functional proteins.
