In this article we will discuss about the control of the synthesis of haemoglobin. 1. The Control of the Rate of Synthesis of the Peptide Chains. i. Rate of synthesis of Normal peptide chains: Approximately 95% of the red cell protein is haemoglobin. The peptide chains of haemoglobins are thus synthesized at a rate much higher than that of any [...]
In this article we will discuss about:- 1. History of Klinefelter's Syndrome 2. Origin of Klinefelter's Syndrome 3. Symptoms 4. Ascertainment and Phenotype 5. Cytogenetic Findings 6. Frequency. History of Klinefelter's Syndrome: 1. In 1942, Klinefelter, Refenstein and Albright found nine men with small testes, aspermia, elevated urinary gonadotrophins and gynecomastics. These persons were later designated as Klinefelter's syndromic. 2. [...]
In this article we will discuss about the intercellular communication in multicellular eukaryotes. In multicellular eukaryotes, the mechanisms that control cell division and cell growth are even more complex because a new dimension intercellular communication must play a major role. Each tissue within an organ and each organ within the body of an organism must grow to the proper size [...]
