In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.n this situation, translation begins at the 5' end of the mRNA while the 3' end is still attached to DNA. In all types of cells, the ribosome is composed of two subunits: the large (50S) subunit and the small (30S) subunit (S, for svedberg unit, is a measure of sedimentation velocity and, therefore, mass).
mRNA. mRNA, or messenger RNA, is the link between a gene and a protein. The gene is transcribed by RNA polymerase, and the resulting mRNA travels to the cytoplasm, where it is translated by ribosomes into a protein with the help of tRNA.RNA, or transfer RNA, is the decoder of the mRNA message during protein translation. After transcription, tRNA is extensively modified to include nonstandard bases such as pseudouridine, inosine, and methylguanosine.
