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.
Simply: the ribosomes, with protein, form rRNA which assemble other proteins together. The ER packages the proteins and sends them to the Golgi apparatus.The Golgi apparatus modifies proteins and either releases them into the cell in endosomes or packages them and sends them out of the cell where the proteins perform their functions.Source(s): Biology major. Jessica Â· 8 years ago.he mRNA leaves the nucleus and randomly moves to a ribosome on the ER (endoplasmic reticulum) Here tRNA brings amino acids (the building blocks of proteins) to the ribsome and they of match up with the code on the mRNA.
