What are protiens and nucleic acid?

Protein, a complex substance in all living things. Proteins are vital to life's chemical processes. Proteins can function as structural material (collagen, keratin), enzymes, hormones, oxygen transporters (hemoglobin), antibodies, or gene expression regulators.

In all living things, including bacteria and viruses, nucleic acids play a crucial role as large biomolecules. To store and express genomic information is a primary role of nucleic acids. Information for protein synthesis is stored in a form of DNA called deoxyribonucleic acid.

Thus, nucleic acid and proteins are significantly different from each other.

Will someone check and see if it is good enough to seem like I tried? Marco Polo (1254-1324) is likely the most renowned westerner who travelled on the Silk Road. He excelled past all other travelers in his decision, work, and effect. The travels of his through the continent lasted 24 years, and he hit farther than any of his forerunners, beyond Mongolia, to Taiwan. He turned into a friend of Kublai Khan, and travelled the whole of Taiwan and returned to tell his story, which eventually turned into a great travelogue. A citizen of the commonwealth of Venice, Polo grew up in a household where both his dad Niccolo and Uncle Maffeo were Merchants. Even before Marco was born, these brothers had journeyed extensively, setting up trading posts as Istanbul, Sudak, Crimea, and the West portion of the Mongol monarchy. They still visited Taiwan occasionally. His dad, Niccolo, traded with the Near East, and grew rich, attaining great prestige. Niccolo and Maffeo set off on the trading journey, just before Marcos own first expedition. In 1260, Niccolo and Maffeo, while residing in Istanbul, then the capital of the Latin Monarchy, anticipated the governmental effect. They liquidated their possessions into jewels and relocated themselves elsewhere. According to the Travels of Marco Polo, they fell through some of the continent, and met with Kublai Khan, the Mongolian ruler and father of the Yuan Dynasty. Their decision to make Constantinople proved to be timely. "The Travels of Marco Polo" turned into a largely popular novel. It was translated into several languages and spread all throughout Egypt. After the decline of Kublai Khan, the Ming Dynasty was the next great empire. They were largely suspicious of any traveller, and little information was free. This made the Novel even more fashionable. His Novel presents a wide and vast-extending display of Kublai Khan's thirteenth century realm. Marco Polo is the Great Khan's messenger who is appointed to go all through his domain. Marco Polo is sent to research and report back his discoveries about individuals, customs, culture, atmosphere, widely varied vegetation, game, winged animals and residence. The Great Khan's realm ranges from the Mideast and the Levant east through all the grounds and realm to the China Sea and islands in it, north to Russia and the polar area and south to the Indian Ocean islands. Marco Polo is accepted to travel farther and more broadly than any other person in the realm of his day. Polos choice to travel was paved by the pioneering endeavors of his ancestors, specifically his dad Niccolo, and his Uncle, Maffeo. His family had dealt with the Middle East for an extension of time, gaining significant wealth and prestige. Although it is questionable if the Polos were of nobility, this was of small value in Venice, the city of Republican and mercantile traditions. This time period was also known as the Golden age of Venice. They left home in 1271 and eventually returned there in 1295. A few years afterwards, Venice defended the battle with the city of Genoa. Marco was place under seizure. While under arrest, Marco told detailed tales of his journeys to an author, whom was named Rustichello, who took note of all of them, and published them in the novel, The Traveling Of Marco Polo. The discovery of the New World, the colonization of the Americas, the American Revolution, and the modern era: all of these great events in humanity may not have occurred in the same way or at all if it was not for one of historys greatest explorers. He traveled the Silk Road, enlightened Europeans to the ways of the East, and inspired future explorers who would be filled with his same drive to catalog the unknown. Yes, history would not have been the same without Marco Polo.
