Abstract
Central dogma units comprise of DNA, RNA and synthesis of protein. Reproductive cycle in shes is always dynamic and the units of central dogma are always changing in different phases of testicular and ovarian cycle which constitute reproductive cycle in shes. The adult specimens of Mystus (M.) vittatus, a tropical siluroid, when exposed for 30 days to sublethal concentration of trivalent arsenic (11.24 mg/l) revealed signicant decline in DNA, RNA and consequently protein in the ovary of Mystus (M.) vittatus during its preparatory phase of Testicular cycle. However, 15 days exposure revealed less signicant alterations. Causes for declining in various units of central dogma and consequently protein synthesis is discussed in this paper.
