Does not have a nucleus. The prokaryotic cell's chromosome float around the cell itself.

Answer:
Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the tRNA anticodon and is congruent with what was actually found by researchers.
Explanation:
A group of researchers led by Seymour Benzer demonstrated that the anticodon of the charged tRNA was recognized by the protein synthesis machinery, when they changed the amino acid sequence. This example shows the exact result as found by the researchers.
The Fossil record is the history of life as documented by fossils, the remains or imprints of the organisms from earlier geological periods preserved in sedimentary rock.
