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. The ribosomes found in the chloroplasts of mitochondria of eukaryotes consists of large and small subunits bound together with proteins into one 70S particle. 2  The ribosomes share a core structure which is similar to all ribosomes despite differences in its size.
