Section 28.11 Three RNAs are involved in gene expression. In the transcription phase, a strand of messenger RNA (mRNA) is synthesized from a DNA template. The four bases A, G, C, and U, taken three at a time, generate 64 possible combinations called codons. These 64 codons comprise the genetic code and code for the 20 anino acids found in proteins plus start and stop signals. The mRNA sequence is translated into a prescribed protein sequence at the ribosomes. There, small polynucleotides called... 

Messenger RNA (mRNA) serves to carry the information or message that is encoded in genes to the sites of protein synthesis in the cell, where this information is translated into a polypeptide sequence. Because mRNA molecules are transcribed copies of the protein-coding genetic units that comprise most of DNA, mRNA is said to be the DNA-like RNA. ...

Parvalbumin was found to be a major fish allergen in approximately 70% of fish allergies, mediated by parvalbumin IgE antibodies, leading to respiratory and gastrointestinal symptoms. Parvalbumin also became of interest because of its potential use in gene therapy to correct cardiomyopathy.

LRP4 is another receptor of the LDL receptor gene family involved in regulation of embryonic patterning, mainly controlling formation of limb structures. Loss of receptor activity in gene targeted mice or spontaneous mutation in bovine cause abnormal limb development and... 

The inhibitors of RNA polymerase, which generates RNA from DNA, inhibit a crucial step in gene expression. Inhibition of the eukaryotic form of RNA polymerase is used in cancer chemotherapy and is also an important experimental tool. For example, actinomy-cin D binds to the guanine residues in DNA and blocks the movement of the eukaryotic RNA polymerase. Specific inhibitors of bacterial RNA polymerase can be used as antibacterial agents. Most of these inhibitors like rifamycin bind to the prokaryotic enzyme. 

Once the TLRs have bound their respective ligand they initiate a signalling cascade to alert the host to the presence of a threat. This signal begins with specific adapter proteins and leads to the activation of transcription factors such as NFkB, ERF-3 and IRF-7 as shown in Fig. 1. These activated transcription factors cause changes in gene expression typically leading to the production of cytokines.
