Did a bit of research on it. The requirement of an architect grind is that the tip needs to be large so that the grind can be effected. My search for a nib to try out lasted till the Jinhao 159 reached. It had a nice tip and a few hours of grind and I got a nice architect nib (with a wee bit of tooth to be honest). Was in my rotation till last week. An italic or a stub is difficult for day to day and work related writing, whereas the architect gives character to writing without appearing too fancy.
The nuclear envelope surrounds the nucleus with a double membrane with multiple pores. The pores regulate the passage of macromolecules like proteins and RNA, but permit free passage of water, ions, ATP and other small molecules.he nucleus of a eukaryotic cell contains the DNA, the genetic material of the cell. The DNA contains the information necessary for constructing the cell and directing the multitude of synthesis tasks performed by the cell in the process of life and reproduction.
Nuclear pores are protein-based channels in the nuclear envelope. They regulate the movement of molecules from the nucleus to the cytoplasm, and vice versa. In most eukaryotic cells, the nucleus is enclosed by this nuclear membrane in order to separate it from the cytoplasm. Many higher eukaryotic cells have as many as 2,000 nuclear pore complexes in the nuclear membrane of each cell. This membrane or envelope keeps the DNA safe, and contains it within the nucleus.
