What is the Difference Between hnRNA and mRNA?

RNA synthesis takes place in the nucleus in eukaryotes. However, when RNA is formed, it is transferred from the nucleus to the cytoplasm. The physiological environment in the nucleus is quite different than than of the cytoplasm. This physiological difference may harm newly formed RNA in the cytoplasm. In order to prevent RNA from any damage, it is processed first and then transferred to the cytoplasm. A...

What is Chargaff's Rule of DNA?

Erwin Chargaff was an Australian biochemist who analyzed nucleic acids of many organisms. From his research, he concluded that the number of purine bases (A, G) equals the pyrimidine bases (C, T) in any double stranded DNA of an organism. It means,  A+G / T+C = 1;  A+T / C+G may vary from organism to organism. % A = % T, and % G = % C Based on Chargaff's rule, many questions are asked...
