1. Scientists have taken genes from a species of bacteria that is pathogenic to several insects and
inserted the genes into potato plants. The bacterial genes cause a cell to produce toxins that kill
the insects. As the potato plants grow, every cell of the plant contains the toxin-producing genes.
This makes the potato resistant to attack by crop pests.
Which of the following is a limitation of this new technology?

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.
