Abstract:
Georgia and Armenia are situated at the northern rim of the thalassemia belt and bordering to countries with a known high prevalence of thalassemias. In this study we assessed the carrier frequency and potential spectrum of alpha- and beta-globin mutations among 202 and 190 unselected Georgian and Armenian subjects, respectively. We found four alpha-globin mutations (-3.7del, -4.2del, anti-3.7 triplication, poly-A2) in 9 Armenians (4.74%) and 4 Georgians (1.78%). The heterozygous beta-globin codon 8 [-AA] mutation was detected in one individual from Armenia only. Overall, carrier frequencies seem to be low in both countries, supporting the notion that thalassemias are not a major health problem there.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
