In this article we will discuss about the non-genetic RNA. Non-genetic RNAs (tRNA, rRNA, mRNA) are synthesized on DNA templates through the process of transcription. The enzyme involved in transcription is "DNA dependent RNA polymerase", or simply "RNA polymerase". In E. coli, a single RNA polymerase catalyzes the synthesis of all kinds of RNAs. In eukaryotes, there are at least [...]
In this article we will discuss about the structure and synthesis of telomere. Structure of Telomere: Molecular genetic studies have shown that the telomere consists of several short sequences which are tandemly repeated (Table 8.8). The general formula for the composition of the repeating units in one strand of the telomeres of all the eukaryotes is as follows: 5' Cn [...]
