  2. Ribosome - Wikipedia

    en.wikipedia.org/wiki/Ribosome

    Affinity label for the tRNA binding sites on the E. coli ribosome allowed the identification of A and P site proteins most likely associated with the peptidyltransferase activity; [5] labelled proteins are L27, L14, L15, L16, L2; at least L27 is located at the donor site, as shown by E. Collatz and A.P. Czernilofsky.

    en.wikipedia.org/wiki/Bacterial_cell_structure

    The 70S ribosome is made up of a 50S and 30S subunits. The 50S subunit contains the 23S and 5S rRNA while the 30S subunit contains the 16S rRNA . These rRNA molecules differ in size in eukaryotes and are complexed with a large number of ribosomal proteins, the number and type of which can vary slightly between organisms.

  5. Cloverleaf model of tRNA - Wikipedia

    en.wikipedia.org/wiki/Cloverleaf_model_of_tRNA

    The model revealed that the chain of tRNA consists of two ends—sometimes called "business ends"—and three arms. Two of the arms have a loop, D-loop (dihydro U loop) and Tψc-loop with a ribosome recognition site. The third arm, known as the "variable arm", has a stem with optional loop. [2]

    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 ...

    Detailed diagram of lipid bilayer of cell membrane The cell membrane , or plasma membrane, is a selectively permeable [ citation needed ] biological membrane that surrounds the cytoplasm of a cell. In animals, the plasma membrane is the outer boundary of the cell, while in plants and prokaryotes it is usually covered by a cell wall .

  9. Ribosomal RNA - Wikipedia

    en.wikipedia.org/wiki/Ribosomal_RNA

    Diagram of ribosomal RNA types and how they combine to create the ribosomal subunits. Both prokaryotic and eukaryotic ribosomes can be broken down into two subunits, one large and one small. The exemplary species used in the table below for their respective rRNAs are the bacterium Escherichia coli ( prokaryote ) and human ( eukaryote ).
