Describe the journey from DNA to protein. Include the following in this order: DNA, gene, mRNA, nuclear pore, Rough Endoplasmic Reticulum, ribosome, protein, transport vesicle, cis-face of the Golgi Body, trans-face of the Golgi Body, lysosome.

A specific segment of DNA (gene) opens and synthesizes a strand of mRNA, through a process called transcription. The mRNA molecule suffers modifications in order to become mature mRNA, then leaves the nucleus through the nuclear pores and goes into the Rough Endoplasmic Reticulum, this is where the mRNA attaches to a ribosome. In the ribosome, translation beings and the mRNA is used to synthesize a protein. The newly synthesized protein leaves the ER through a transport vesicle and then arrives at the cis-face of the Golgi Body for further processing. The modified protein then leaves through the trans-face of the Golgi Body in a transport vesicle. This protein will function until it ages and deteriorates, to then arrive at the lysosome to be dissolved and turned back into amino acids.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
