DNA and Importance of Proteins | Molecular Biology

The length of DNA double helix is calculated in a typical mammalian cell (simply by multiplying the total number of bp with distance between two consecutive bp, that is, 6.6 x 109 bp x 0.34 x 10-9m/bp), which approximately comes out to be 2.2 meters. A length that is far greater than the dimension of a typical nucleus (approximately 10-6 [...]

Protein Synthesis: Control of Protein Synthesis |Biology

Control of Protein Synthesis! (i) A Mechanism for the control of protein synthesis by Adenovirus VA RNAI: In the absence of VA RNAI protein synthesis process fails in adenovirus infected HeLa cells. This is due to defective initiation. The defect results from phosphorylation of the initiation factor elF-2 on its alpha subunit. The protein kinase is responsible as the DSRNA-activated [...]
