(20 points) a teacher shows the class a neutral atom of bromine that has an atomic number of 35 and has 45 neutrons. jackie said, "i think the atomic mass would be 45, because there are 45 neutrons and neutrons make up the mass of the atom" pauly said, "i think the atomic mass would be 80, because there are 45 neutrons and 35 protons. both of these have a mass of about 1." sam said, "there would be 45 electrons and 45 protons, because of the atomic number." who is correct? question 8 options: a. only pauly is correct. b. both sam and pauly are correct. c. only sam is correct. d. both sam and jackie are correct.

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.
