The question is incomplete. The complete question is as follows;
Imagine you are following a particular tRNA, called tRNAQ, through the process of translation in a eukaryote. In what order does tRNAQ go through the steps listed below? (Note that some steps may be used more than once.)
1. The polypeptide is transferred to tRNAQ.
2. tRNAQ binds the A site of the ribosome.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
3, 4, 1, 4, 2, 4, 5
3, 1, 4, 2, 4, 5
2, 4, 1, 4, 2, 4, 5
5, 1, 4, 3, 4, 5
2, 1, 4, 3, 4, 5
Answer:
2, 1, 4, 3, 4, 5.
Explanation:
The translation process involves the different types of RNA, ribosome and different translation factors. This process results in the formation of the protein product from the RNA molecule.
The ribosome contains the three site known as A site (entry site), P site ( peptidyl site) and E (exit site). The tRNA Q must enter first to the A site and contain some initiation factors. tRNA Q contains the specific anti codon that are complementary to the codon present on the mRNA. The polypeptide is the attached to the tRNA Q. This allows the movement of ribosome over mRNA and tRNA Q will enter in P site. The ribosome shifting still occurs and then tRNA Q enter the E site and later exits from the ribosome.
Thus, the sequence is 2, 1, 4, 3, 4, 5.
Absorptive cells are responsible for completing digestion by removing nutrients from chyme and transferring them into capillaries or lymph vessels in the digestive system. These cells are typically found in the lining of the small intestine, where nutrient absorption takes place.

The reason why Koala bears are restricted to live in a certain habitat is because they can only eat a certain type of eucalyptus leaf. These bears are indigenous to Australia. They are nocturnal and live in tropical where temperate eucalyptus forest can be found.
Answer:
Only eat a certain type of eucalyptus leaf
Explanation:
Koala bear are found in restricted geographical regions only since they eat only certain type of eucalyptus leaves. Koala bear prefer a habitat rich in eucalyptus trees and receiving adequate rainfall. The leaves of eucalyptus trees are rich in water which is essential for Koala bear. They are found in coastal islands and inland woodlands that are habitat for eucalyptus species as preferred by Koala bears.
