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).
During transcription the gene (double-stranded DNA) is copied or transcribed into an virtually identical single-stranded messenger RNA molecule (mRNA). In eukaryotes this process occurs in the nucleus. Transcription: 1) RNA polymerase transcribes DNA to make messenger RNA (mRNA).2) The mRNA sequence (dark red strand) is complementary to the DNA sequence (blue strand). Translation: 3) On ribosomes, transfer RNA (tRNA) helps convert mRNA into protein.n eukaryotes this process occurs in the nucleus. Transcription: 1) RNA polymerase transcribes DNA to make messenger RNA (mRNA). 2) The mRNA sequence (dark red strand) is complementary to the DNA sequence (blue strand).
