A vaccine is a preparation of one or more microbial antigens to induce protective immunity in potential hosts.

Vaccines are the anti-microbial agents administered to provide immunity against specific diseases. There can be a wide variety of vaccines, like: live attenuated vaccine, vaccine with killed or inactivated microbes, vaccine containing the sub-parts of the microbes, etc.

Immunity is the body's ability fight against a disease. The immunity is build when a body gets attacked by pathogen. Various immune cells like neutrophils, MHCs, dendritic cells, B and T cells, etc. are involved in building and strengthening the immunity of any person.

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.Match the wo
vredina [299]

1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.

tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with  the amino acids they encode.tRNA has anticodone that binds to mRNA codone.

2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.

Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).

3. Initiation of translation always happens at the start codon of the mRNA.

Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).

4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.

These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.

5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.

Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
