The basic concept of molecular biology is to investigate the activities of an organism's makeup at a sub-cellular level. The focus is on the sequence of the DNA (the genes), the rate and timing of the expression of those genes, the mechanisms involved in expressing those genes, and the effect that they have on the whole cell and ultimately the [...]
Some of the most important techniques used in molecular biology are as follows: Molecular Biology techniques include characterization, isolation and manipulation of the molecular components of cells and organisms. These components include DNA, the repository of genetic information; RNA, functional and structural part of the translational apparatus and proteins, the major structural and enzymatic type of molecule in cells. (i) [...]
Some of the major steps of DNA transcription are as follows: (i) RNA Polymerase binds to DNA (ii) Elongation of DNA takes place (iii) Termination of DNA takes place. A process that involves the transcribing of genetic information from DNA to RNA is DNA transcription. Colored image 4.9 explains DNA transcription. Protein is produced by the transcribed DNA message. DNA [...]
