Insect pests often feed on crop plants in farmers' fields. To address this problem, scientists have developed transgenic crop plants that produce their own pest-killing chemicals. In nature, these chemicals are produced by certain bacteria.

Which of the following actions was MOST LIKELY involved in the development of the transgenic crop plants?

A. Sections of the genome of the host plant were spliced and removed.
B. DNA from the host plant was inserted into the genome of bacteria.
C. Recombinant DNA was inserted into the genome of the host plant.
D. The host plant was artificially crossed with an insect pest.

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.
