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.
The DNA appears as swirls in the center of the cell, and the ribosomes appear as dark particles at the cell periphery.Courtesy of Dr. Abraham Minsky (2014). All rights reserved. Ribosomes are the sites in a cell in which protein synthesis takes place.Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).fter the transcription of DNA to mRNA is complete, translation â or the reading of these mRNAs to make proteins â begins. Recall that mRNA molecules are single stranded, and the order of their bases â A, U, C, and G â is complementary to that in specific portions of the cell's DNA.
