State the principles of immunisation. |
|
Answer» ation can be defined as process by which an individual is made immune or RESISTANT to an infectious DISEASE by ADMINISTRATION of an external agent (vaccine). The basic principle of immunization is that on administration of the vaccine, the body starts developing antibodies against it such that the person is protected or immunized from the disease. Body remembers the infectious agent and memory cells are formed which can immediately PRODUCE antibodies on further exposure to the infectious agent. HENCE, the person fights the infection with the help of pre-existing antibodies and is immunized from the disease...✧══════•❁❀❁•══════✧. |

The growing polypeptide chain exits the ribosome through a slot in the |
|
Answer» e here is u r answer>>>>....TRANSLATION Protein synthesis occurs on 'workbenches' called ribosomes in a process called translation. In translation, all 3 primary types of RNA cooperate. mRNA (messenger RNA) carries the genetic information transcribed from DNA to the ribosome; tRNA (transfer RNA) molecules carry specific amino acids to the ribosome to be added to the growing chain; and RRNA (ribosomal RNA), along with proteins, make up ribosomes. RIBOSOME A ribosome has 3: the A site, the P site, and the E site. The A (aminoacyl) site is where amino acids arrive at the ribosome, carried by their respective tRNA molecules. The P (peptidyl) site is where the growing polypeptide is located, attached to the tRNA docked there. The E (exit) site is where a tRNA that has no amino acid attached it is positioned just before it leaves the ribosome. GENETIC CODE A ribosome "reads" an mRNA molecule 3 bases at a time; a set of 3 consecutive mRNA bases that are read as a single unit is called a codon. Because there 4 possibilities (A, C, U, or G) at each of 3 positions, there are a TOTAL of 4^3 = 64 possible codons. The genetic code is the mapping of each of the 64 possible codons to its corresponding amino acid; in a few cases, a codon maps instead to either a START or STOP signal Translation consists of 3 stages: initiation, elongation, and termination. INITIATION There are two separate subunits for a ribosome: a large subunit and a small subunit. The two are separate most of the time, but when mRNA binds to one of them, the other subunit binds to the complex, forming a ribosome and initiating translation. ELONGATION As a given codon sits in the A site, tRNA molecules randomly BUMP into the slot, but they don't dock. Only when a tRNA with a 3-base anticodon that is complementary to the codon in the A site arrives does docking occur. The specific tRNA molecule that docks carries a specific amino acid to the ribosome (this is how codons indirectly code for specific amino acids). The growing polypeptide attached to the tRNA docked in the P site is transferred to the newly arrived amino acid attached to the new tRNA molecule docked in the A site. During a process called translocation, the ribosome moves exactly 3 bases along the mRNA,.This physical shifting CAUSES repositioning of the tRNAs too. The tRNA in the E site leaves the ribosome; the tRNA in the P site is shifted over to the E site; and the tRNA withe growing polypeptide attached shifts from the A site to the P site. All of this positions the next codon to be read into the now-empty A site. The ribosome has been restored to its beginning position, but with the polypeptide now being 1 amino acid longer. These elongation steps are repeated over and over, once per amino acid added to the chain. We can break elongation down into steps. (1) Codon recognition: A tRNA carrying the correct amino acid (determined by complementarity between the tRNA’s anitcodon and the mRNA’s codon) docks in the A site. (2) Peptide bond formation: The existing, growing polypeptide is transferred from the tRNA molecule in the P site to the amino acid on the new tRNA in the A site. (3)Translocation: The ribosome moves 3 bases along the mRNA, moving the uncharged tRNA in the P site into the E (exit) site, the tRNA in the A site (with the polypeptide now attached) into the P site, and positioning a new codon into association with the now-empty A site. (4) Back to step (1) TERMINATION Eventually, a STOP codon is reach, positioned in the A site. A STOP codon does not code for an amino acid, but for a release factor. The release factor binds, dissociating the ribosome into its two subunits and releasing the mRNA and the polypeptide. The polypeptide will then fold into a stable tertiary structure to become a protein |
