Lecture´s Description

Bacterial Gene Structure
In this lecture ´´Bacterial Gene Structure and Transcription´´ is explained. Section one is about ´´Bacterial Gene Structure´´. Educator begins this section by discussing genes and hypothesis. After that protein-coding genes are explained. Then template strand is focused. This is followed by explanation of promoter. In the end, leader sequence is pursued.


Coding region, rRNA and tRNA Genes
Section two is about ‘’Coding region, rRNA and tRNA Genes’’. Initially, coding region - start codon is discussed. The discussion continues on stop codons - terminator site. After that tRNA and rRNA Genes comes under consideration. Lastly, ribosomal RNA genes are pursued.


Transcription Machinery
Section three is about ‘’Transcription Machinery’’. At first, types of RNA are elucidated. Next focus is the polycistronic mRNAs. This is followed by monocistronic mRNAs. Furthermore, bacterial RNA polymerases are discussed. In the end, pribnow box is thoroughly explained.


Stages of Transcription
Section four is about ‘’Stages of Transcription’’. Educator's prime focus is the explanation of stages of transcription. The first step is the initiation of transcription. The discussion continues on elongation. Then termination is elaborated. At last, information is conveyed about factor dependent terminator.


Genetic Code
Section five is about ‘’Genetic Code’’. Educator talks about codons. Then gives information about set of codons. Likewise, explains wobble base pairing. This is followed by exceptions to genetic code.
