Procedure: Using lodine, which stains starch a dark-blue/black color, you will determine the presence of starch in a solution and the effect that amylase has on the
starch. After adding iodine, if the solution remains the color of the iodine solution itself,
then starch is not present; the amylase has hydrolyzed it into maltose molecules which no
longer react with iodine. In this way, you can determine the time it takes for the reaction to
run its course...

What is the difference between how ionic and covalent bonds form

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.
