Studies on the correlation between DNA, RNA and proteins of Bombyx mori L

Four pure mulberry silkworm breeds viz., Pure Mysore, Nistari, NB4D2 & CSR2 and two hybrid (Pure Mysore x CSR2 and Nistari x NB4D2 ) silkworms were selected for the present study. The total DNA, RNA and soluble proteins present in the mid alimentary canal was estimated during fifth instar with a regular interval of 24 h, and the average concentration during fifth instar was calculated. The average concentration of DNA, RNA and proteins were subjected to regression analysis with each other individually to know the kind and level of correlation coefficient between them. The results of regression analysis between DNA and RNA as well as between RNA and Protein exhibited very strong level of correlation coefficient between them. The average concentration of DNA and protein exhibited moderately strong positive relationship between them. The concentration of DNA, RNA and protein as well as their ratios are more in hybrid silkworms
