In the quaternary structure of a protein the polypeptide is folded through the mechanism of amino acids rotating around bonds and folding into a alpha-helix or beta-pleated sheet structure and stabilized by bonds. amino are the building blocks of proteins. They are made up of a center carbon atom bound to a positively charged group and a negatively charged group and a side chain. In the secondary structure of a protein the amino acid side chains of the folded polypeptide interact, forming a complex three-dimensional shape. primary structure formed by amino reactions link amino acids together, forming a linear chain. The of a protein exists if multiple polypeptides bind together to form a functional protein.

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
