Question

use the examples of dna and protein structure to explain the importance/significance of hydrogen bonding (2 - 3 sentences).
match the protein or the function that correctly correspond to each other.
transport and storage
enzyme
actin and myosin
antibodies
structural support/adhesion proteins
protein on the surface of a cell
lactase (breaks down lactose in milk) hemoglobin proteins involved in the immune response
receptor collagen and fibrinogen contractile proteins

Explanation:

Hydrogen bonding is crucial in DNA for holding the two strands together (A - T, C - G base pairs via hydrogen bonds), enabling replication and transcription. In proteins, hydrogen bonds stabilize secondary structures (alpha - helices, beta - sheets), which are essential for the protein's overall 3D shape and function.

Answer:

Hydrogen bonding is vital for DNA's double - helix structure (holding base pairs) and protein secondary structure (stabilizing helices/sheets), thus enabling their biological functions.
