Which statement correctly explains the polarity of the water molecule?
the hydrogen end of the molecule has a partial negative charge and the oxygen end has a partial positive charge.
the oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
both ends of the molecule have a partial negative charge, which attracts the other water molecule towards its

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.
