As bile is produced and secreted, what structures or cells does it encounter?
eimsori [14]

The order is Hepatocyte, Bile canaliculus, Common hepatic duct, Cystic duct, and Gallbladder.

<h3>What is bile?</h3>

The liver of most vertebrates produces bile, also known as gall, which is a dark-green to the yellowish-brown fluid that aids in the small intestine's breakdown of lipids. Bile is continuously created by the liver in humans (liver bile), and it is stored and concentrated in the gallbladder. Hepatic bile is made up of 200 meq/l inorganic salts, 0.7% bile salts, 0.2% bilirubin, 0.5% lipids (cholesterol, fatty acids, and lecithin), and 97-98% water. Biliverdin, a green oxidized version of bilirubin, is one of the two primary pigments in bile. They combine to give feces their specific brown hue color. Adult humans produce about 400 to 800 milliliters of bile every day.

Explain how the triplet code of dna is transcribed and translated in the synthesis of proteins
timama [110]
Ok this is going to be a long answer lol


Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.



During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

I hope this helps :)
