A transfer RNA (#1) attached to the amino acid lysine enters the ribosome. The lysine binds to the growing polypeptide on the ot

her tRNA (#2) in the ribosome already. Where does tRNA #2 move to after this bonding of lysine to the polypeptide?

Options for the question have not been give. They are as follows:

A. P site

B. A site

C. E site

D. directly to the cytosol

E. exit tunnel

Answer:

C. E site

Explanation:

Translation is the process by which mRNA is converted into polypeptide chain. Translation machinery has three binding slots for tRNA : A, P and E. Any incoming tRNA encounters A, P and E site in that order.

When a new tRNA (#1) carrying the next amino acid (here, lysine) comes, it enters the A site. Peptide bond is formed between lysine and the already existing amino acid on the growing polypeptide chain on the preceding tRNA (#2). Once lysine is added to the polypeptide chain, the entire chain moves to tRNA #1 which makes tRNA #2 empty. Meanwhile, the machinery moves forward. As a result, tRNA #1 slides to P site and tRNA #2 slides to E site. The A site is empty now and can receive another tRNA.

Simora [160]

The answer is; warming of ocean water in the east of the Pacific Ocean close to the western coasts of South America.

The warming of the oceanic waters causes a current that pushes the warm waters eastwards of the Pacific Ocean at the equator.  This counters and overpowers the prevailing trade winds that blow westwards. The currents bring in storms on the West coast of South America as the currents exchange heat with the atmosphere .

Which of the following statements gives the most fundamental reason why ornithine is unlikely to be found in proteins synthesize
BlackZzzverrR [31]

Answer:

option A

Explanation:

ornithine is a non-protein and non-essential amino acid it is formed in plant by L-glutamate and in animals it is formed during the urea cycle by the catalyzation of arginine which is an enzyme. In vivo ornithine is not found in protein synthesis because it do not have any codon so it can not endoded by DNA but can be synthesized.

Ornithine is a precursor of glutamic acid, proline amino acid and citrulline amino acid

What is the major sink reservoirs for the nitrogen cycle?
Rudiy27

All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
