In this article we will discuss about the physico-chemical properties of nucleic acids. The size of nucleic acids varies immensely. The smallest ribonucleic acids are the tRNAs which comprise about 80 nucleotides; their molecular weight is about 30 000. Ribosomal ribonucleic acids are larger; they contain several thousands of nucleotides and their molecular weight can […]

The replication of numerous procaryotes was studied in recent years. The mechanisms of the replication of phages T4, T7 and λ are now well known, while those of B. subtilis are beginning to be understood. However, the most extensively studied system remains Escherichia coli, thanks to the combination of various types of approaches. Experimental Approaches […]

In this article we will discuss about the secondary structure of Deoxyribonucleic Acids (DNA) and Ribonucleic Acids (RNA). Secondary Structure of Deoxyribonucleic Acids: Some observations made on deoxyribonucleic acids in solution suggested that DNA molecules — as they could be extracted from cells — had structural characteristics different from those expected in molecules having only […]
