The below mentioned article provides notes on palindromic DNA. In the DNA molecule a variety of base sequences have been observed. Most of them do not have special features. The repeated sequences are of particular interest because they are the site of enzymatic activity and, sometimes give special features to the nucleic acid. For the first time Wilson and Thomas [...]
The mRNAs found in prokaryotes differ from that of eukaryotes in the following ways: (i) The prokaryotic mRNAs are broken down by the ribonuclease into ribonucleotide, hence these are very short lived e.g. 2 minutes in E.coli. The short lived nature is due to changes in environmental conditions. In contrast the eukaryotic mRNAs have longer life i.e. they are metabolically [...]
In this article we will discuss about the characteristics of fungi. The fungi are cosmopolitan in distribution, some are aquatic, others are terrestrial and still others are air borne. Many are parasitic on plants, animals and human beings. The plant body typically consists of branched and filamentous hyphal form, a net like structures called as mycelium. The hyphae are aseptate [...]
