Lecture´s Description

Gene
In this lecture ´´Molecular Structure of Genes´´ is explained. Section one is about ´´Gene´´. Educator gives definition of gene. After that structure of gene is illustrated. Prokaryotic mRNA and eukaryotic mRNA are discussed. Then bacterial polycistronic mRNA is elaborated. Following this, eukaryotic monocistronic mRNA is explained. Moving onward, transcription unit is elucidated in detail.


Gene Organization and Non-Coding DNA
Section two is about ‘’Gene Organization and Non-Coding DNA’’. At first educator comprehensively elucidates non-functional DNA. After that types of genes are discussed. Then tandemly repeated genes come under consideration.

Repetitious DNA
Section three is about ‘’Repetitious DNA’’. Initially, simple-sequence DNAs are pursued. Then microsatellites and diseases are elaborated. In the end, DNA fingerprinting is elaborated.


Mobile DNA
Section four is about ‘’Mobile DNA’’. Educator begins with the elaboration of transposable elements. After that transposition is discussed. Following this, explanation continues on prokaryotes and eukaryotes transposons.


Retrotransposons
Section five is about ‘’Retrotransposons’’. In the beginning, viral retrotransposons are discussed.  After that long interspersed elements (LINES) are pursued. This is followed by in depth elucidation of small interspersed elements (SINES). Then mobile DNA elements and evolution is explained.
