Given the mRNA sequence below, what would tRNA anticodons be in response? A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A
Lesechka [4]

Answer:

U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Explanation:

The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).

The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.

Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Suppose you treated butter with a fatty acid desaturase, an enzyme that removes hydrogen from fatty acids and creates double bon
LekaFEV [45]

When a butter is treated with fatty acid desaturase, the hydrogen atom will be removed and form a carbon double bond, which allow the membrane to become more fluid. When temperatures change, a phase transition occurs. If the temperature decrease, the membrane gels becomes solid which then results to cracks and the imbedded proteins cannot partake in conformational changes, thus it is important to maintain membrane fluidity.

What happens first when the amount of sunlight decreases?
dezoksy [38]
Light energy absorbed by chlorophyll is converted into chemical energy. Some of this energy is used to split water into hydrogen and oxygen. Some of the chemical energy is used to make ATP from ADP and phosphate (Pi). This chemical energy is stored as ATP.

How did the explosion of the USS Maine in Havana Harbor in February of 1898 help lead to the annexation of Hawaii? A) As a resul
krok68 [10]

Answer:

By 1795, the warrior chief, Kamehameha the Great, had conquered most of the Hawaiian islands and established a monarchy. In the 1820s, American whalers, traders, and Christian missionaries began to visit and settle in the kingdom of Hawaii.

Although a small minority, the Americans in Hawaii soon owned much of the land, which they began to turn into large sugar-cane plantations. The native Hawaiian population dropped sharply due to smallpox and other diseases that came with the American immigrants. Needing more workers, the sugar planters imported Chinese and Japanese contract laborers who agreed to work on the plantations for a set period of time.

As their influence increased, the Americans became deeply involved with the government of the Hawaiian kings. In 1840, American advisors helped King Kamehameha III produce Hawaii's first written constitution.

By 1842, the United States had developed regular diplomatic relations with Hawaii and supported its status as an independent country. After King David Kalakaua ascended the throne in 1874, Hawaii and the United States signed a trade agreement lifting some restrictions on exporting Hawaiian sugar to the United States. In addition, this agreement permitted the United States to lease a naval station at Pearl Harbor.
