TRNA stands for transfer-RNA which is used in the process of protein synthesis or translation. tRNA is a unique clover leaf like structure that has 4 arms- amino acid acceptor site (acceptor arm), D loop, T psi C loop and anticodon loop. It also has a small variable loop. The anticodon loop consists of a sequence of 3 bases that is complementary to the 3 bases present of mRNA to be translated. A tRNA for alanine will have an anticodon for alanine while a tRNA for lysine will have an anticodon for lysine. For a tRNA to insert an alanine in place of lysine in a forming peptide, the anticodon and the amino acid acceptor site should be altered so that it accepts lysine in place of alanine and add it to the growing polypeptide.

In terms of the scientific method, the purpose of an experiment is to:
D) Test a hypothesis
After forming a hypothesis, you TEST it out by performing the experiment and collecting data. After collecting the data from the experiment, you can form a conclusion about the results of the experiment.
An experiment is supposed to tell you whether the hypothesis you came up with is true and is able to be proven with an experiment.
The purpose of an experiment is to test a hypothesis and see whether the results you get support or contradict your hypothesis.
Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent).
Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust.
Answer: Microscopic organisms are not made of cells.
All things that are living are made of cells.
