Theories may change over time. In ancient times, people observed that living things seemed to arise from nonliving things. They observed that maggots would
often appear on rotting meat. This became known as the Theory of Spontaneous
Generation and was widely accepted for many years. In 1668, Anton van
Leeuweenk invented the microscopes which allowed him to see microorganisms
for the first time. Upon observing the rotting meat under magnification, scientists
changed their understanding of living things.
What theory did this new information lead to?

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
