Tadalafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, tadalafil works by increasing blood flow to the penis to help a man get and keep an erection. Tadalafil is also used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH).
Which part of the cell assembles precursors of ribosomes within the nucleus? Answer. The nucleolus (also called nucleole) is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus and is the part of the cell assembles precursors of ribosomes within the nucleus.
In eukaryotes, ribosomes form in the nucleolus, a structure inside the cellâs nucleus. As ribosomal proteins enter the nucleus, they join with four rRNA strands to create a complete ribosome. The subunits exit the nucleus through pores and begin protein synthesis in the cytoplasm of the cell. In prokaryotes, proteins combine with three rRNA strands. Since prokaryotes do not have a membrane-bound nucleus, ribosomes form within the cytoplasm.
