Read this article to learn about the three types of mutations helpful in determining the role of a particular gene. The three types of mutations are: (1) Operator Mutations (2) Repressor Mutations and (3) Structural Gene Mutations. A mutation in any sequence of promoter or structural gene results in changed gene expression, e.g., altered protein, non-transcription etc. Some of the [...]
This article throws light upon the top four methods of gene transfer. The top four methods of gene transfer are: (1) DNA Transfer in Protoplasts (2) Free DNA Transfer to Intact Tissue (3) Agrobacterium Mediated Gene Transfer Method and (4) Integration and Expression. The first transgenic plant was produced via Agrobacterium mediated modified transformation of Nicotiana tabacum protoplasts by Horsch [...]
This article throws light upon the top three things to know about gene expression. The top three things about gene expression are: (1) RNA Polymerase of Prokaryotes (2) Process of Transcription in Prokaryotes and (3) Process of Transcription in Eukaryotes. Introduction: Transcription is the process by which genetic information from DNA is transferred into RNA. DNA sequence is enzymatically copied [...]
