Aminoacyl-tRNA synthetases recognize their specific amino acid by charge, size and R group and recognize the tRNAs that carry it by the nucleotide sequence .
Aminoacyl-tRNA synthetases are enzymes that attaches the appropriate amino acids on to its tRNA . These are also responsible for performing the first step of protein synthesis.
Varicella Zoster Virus (VZV) causes varicella or chicken pox in humans. Chicken pox is generally found in children of 1 to 9 years of age but the virus can also infect the adults. The VZV infection becomes more complicated if it occurs in a pregnant woman.
Every pregnant woman should be checked for VZV infection. If a woman did not get affected with VZV will not have the antibodies against the virus. Such woman should be given varicella vaccine.
In a VZV infected pregnant woman the following symptoms can be seen such as fever, myalgia, malaise and painful skin rashes. The lesions or rashes first appear on the head and trunk that spreads to the lower parts of the body. The disease becomes complicated if pneumonia and encephalitis also occurs along with VZV infection.
<span>This gene sequence undergoes transcription to produce mrna by rna polymerase, and other proteins. This occurs in the nucleus of a eukaryotic cell. While prokaryotic cells lack the same type of nucleus that has organizational skills, the eukaryotic cell has this nucleus and contains various organelles for completion of this process.</span>
