the amino acids detach from the ribosome
In the context of ribosomes during protein synthesis, the P site (peptidyl site) and A site (aminoacyl site) are two key binding sites for tRNA. The A site is where the aminoacyl-tRNA, carrying the next amino acid to be added, binds during translation. The P site holds the tRNA that carries the growing polypeptide chain. This coordinated action facilitates the addition of amino acids to the growing protein chain during translation.
The P site and the A site of the ribosome hold the growing polypeptide chain during translation. The P site is where the tRNA carrying the growing polypeptide is located, and the A site is where the new tRNA carrying the next amino acid in the sequence enters.
If a eukaryotic ribosome had only one tRNA binding site, it would be unable to function in protein synthesis. The P site is where the tRNA carrying the growing polypeptide chain binds, while the A site is where the incoming aminoacyl-tRNA binds. Without these distinct sites, the ribosome would not be able to coordinate the movement of tRNAs during translation.
You'll have to watch it to find out! :P
i dun kno you tell me :P
Nothing happens. Or in other words, it just end like normal. And they kill a rat :P
A tRNA moves through the ribosome binding sites in the following order: A (aminoacyl) site, P (peptidyl) site, and finally E (exit) site. This movement occurs during the process of translation where the tRNA delivers amino acids to the growing polypeptide chain.
The P site of the ribosome stands for peptidyl-tRNA site, as it is where the peptidyl-tRNA molecule is positioned during protein synthesis. The naming convention for ribosome sites comes from the type of molecule that occupies each site during translation.
During the initiation step of translation, the fMet-charged tRNA assembles in the P site of the ribosome. This site accommodates the first aminoacyl-tRNA, which carries the modified methionine (fMet) in prokaryotes. The initiation complex then facilitates the proper alignment of the mRNA and the start codon, allowing translation to commence.
During translation, tRNA molecules are ejected from their amino acids during the translocation step. After the peptide bond formation between the amino acids, the ribosome shifts along the mRNA, moving the tRNA in the A site to the P site. Consequently, the tRNA in the E site, which has already donated its amino acid, is released from the ribosome. This process allows for the next tRNA to enter the A site, continuing the translation cycle.
The translation T(4, 4) means that you add 4 to the x-coordinate and 4 to the y-coordinate of point P(x, y). Therefore, the coordinates of the image of point P after the translation will be P'(x + 4, y + 4).
The large ribosomal unit has three binding sites for tRNA molecules: the A site (aminoacyl-tRNA), the P site (peptidyl-tRNA), and the E site (exit site). These sites are crucial for the proper assembly of amino acids into a growing polypeptide chain during translation.
