  2. Translation (biology) - Wikipedia

    en.wikipedia.org/wiki/Translation_(biology)

    Overview of eukaryotic messenger RNA (mRNA) translation Translation of mRNA and ribosomal protein synthesis Initiation and elongation stages of translation involving RNA nucleobases, the ribosome, transfer RNA, and amino acids The three phases of translation: (1) in initiation, the small ribosomal subunit binds to the RNA strand and the initiator tRNA–amino acid complex binds to the start ...

  3. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Eukaryotic translation is the biological process by which messenger RNA is translated into proteins in eukaryotes. It consists of four phases: initiation, elongation, termination, and recapping. It consists of four phases: initiation, elongation, termination, and recapping.

  4. Transfer RNA - Wikipedia

    en.wikipedia.org/wiki/Transfer_RNA

    The existence of tRNA was first hypothesized by Francis Crick as the "adaptor hypothesis" based on the assumption that there must exist an adapter molecule capable of mediating the translation of the RNA alphabet into the protein alphabet. Paul C Zamecnik, Mahlon Hoagland, and Mary Louise Stephenson discovered tRNA.

  5. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    Messenger RNA (mRNA) is the type of RNA that carries information from DNA to the ribosome, the sites of protein synthesis (translation) in the cell cytoplasm. The coding sequence of the mRNA determines the amino acid sequence in the protein that is produced. [27]

  6. Central dogma of molecular biology - Wikipedia

    en.wikipedia.org/wiki/Central_dogma_of_molecular...

    A second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965). Watson's version differs from Crick's because Watson describes a two-step (DNA → RNA and RNA → protein) process as the central ...

  7. Protein biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Protein_biosynthesis

    Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. [1] Protein synthesis can be divided broadly into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a molecule called messenger RNA (mRNA).

  8. Post-translational modification - Wikipedia

    en.wikipedia.org/wiki/Post-translational...

    Phosphorylation is highly effective for controlling the enzyme activity and is the most common change after translation. [ 2 ] Many eukaryotic and prokaryotic proteins also have carbohydrate molecules attached to them in a process called glycosylation , which can promote protein folding and improve stability as well as serving regulatory functions.

  9. Post-transcriptional modification - Wikipedia

    en.wikipedia.org/wiki/Post-transcriptional...

    The pre-mRNA processing at the 3' end of the RNA molecule involves cleavage of its 3' end and then the addition of about 250 adenine residues to form a poly(A) tail.The cleavage and adenylation reactions occur primarily if a polyadenylation signal sequence (5'- AAUAAA-3') is located near the 3' end of the pre-mRNA molecule, which is followed by another sequence, which is usually (5'-CA-3') and ...
