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.
rRNA is synthesised in the nucleus, in a special part called the nucleolus. rRNA leaves the nucleus where it forms part of organelles called ribosomes which are the site of protein synthesis. Ribosomes can be free in the cytoplasm or attached to special membrane-bound organelles called rough endoplasmic reticulum (RER).est Answer: mRNA is synthesised in the nucleus. It is a copy of the genetic code held in DNA. It then passes out into the cytoplasm of the cell to be involved in protein synthesis.
