Jane's dog Skippy has 78 chromosomes in each cell. One day, Skippy jumped into a tree while lunging for a frisbee. This left him with a cut on his nose. Luckily, mitosis occurs to help repair the cut. After mitosis, how many chromosomes does each of Skippy's daughter cells have if each original cell had 78 chromosomes?

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.

What molecules will be best used to compare different species with the exact same sequence of amino acids? why would two species have the same protein even if the molecules in question is different? (hint: transcription to translation to protein).
