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.
1 The subunits of the ribosome are synthesized by the nucleolus. 2  The subunits of ribosomes join together when the ribosomes attaches to the messenger RNA during the process of protein synthesis. 3  Ribosomes along with a transfer RNA molecule (tRNA), helps to translate the protein-coding genes in mRNA to proteins. Ribosomes in a cell are located in two regions of the cytoplasm. 2  They are found scattered in the cytoplasm and some are attached to the endoplasmic reticulum. 3  When the ribosomes are bound to the ER there are known as the rough endoplasmic reticulum.
