What data provide support for the plate tectonic theory?

detailed research of the ocean floor
shape of the continental coastlines matching up together
lava flows that match up on different coasts of different continents
rock layers that match up on different continents

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
