Talking of early development we are referring to the embryonic
stage of development. The closer similarity of their embryos shows a relationship
between the organisms. For example an adult chimpanzee and an adult human being
look so different and on the other hand their embryos look so much alike.
Competition is where you go up against somebody
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.
