Witryna19 lip 2024 · Dimensions of B-form (the most common) of DNA 0.34 nm between bp, 3.4 nm per turn, about 10 bp per turn 1.9 nm (about 2.0 nm or 20 Angstroms) in diameter Major and minor groove The major groove is wider than the minor groove in DNA (Figure 2.5. 2 d ), and many sequence specific proteins interact in the major groove. WitrynaFor this reason, the DNA is protected and packaged in very specific ways. In addition, DNA molecules can be very long. Stretched end-to-end, the DNA molecules in a single human cell would come to a length of about 2 meters. Thus, the DNA for a cell must be packaged in a very ordered way to fit and function within a structure (the cell) that is ...
