Answer:
The correct answer is The bridge between cystein which connects parts of a protein is stable but non covalent interaction.
Explanation:
Disulfide bond link the sulfhydryl group of two adjacent cystein residues in a protein structure.
Dulsulfine bond is stable but is not a non covalent interaction.Disulfide bond itself is a covalent interaction.
The most true answer from these choices is:
Methyl groups most often added to guanine-cytosine base pairs because they are held by three hydrogen bonds, and this decreases the probability of gene expression.
Answer: Seafloor spreading occurs at <u>divergent plate boundaries.</u> As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
