A bacterial infection of the periodontium that causes rapid attatchment loss and poor response to periodontal therapy has a grade of Aggressive periodontal disease
<h3>Periodontium </h3>
The cementum, gingiva, periodontal ligament (PDL), and alveolar bone make up the complex structure known as the periodontium. The periodontium's main purposes are to protect the underlying structures of the tooth from the oral microflora and to enable the tooth to connect to the bone.
An orthokeratinized or parakeratinized stratified squamous epithelium makes up the gingival epithelium. The gingiva, which has connective tissue and epithelial components, covers the supracrestal root surface and the alveolar bone. As it lines the gingival sulcus close to the tooth surface (enamel or cementum) and subsequently joins to it with hemidesmosomes, the gingival (oral) epithelium develops into the sulcular epithelium and junctional epithelium.

It requires energy when a substance must travel against a concentration gradient through the membrane
Answer:
The biologist should have a look at the structure of the protein. Since all functions are largely dependent on the structure of the protein (another way to look at it would be that proteins are specialized to carry out their functions because of how they are structured), this is determined by the amino acid sequence of the protein. And the sequence of amino acids is given by the DNA sequence, so that is what the biologist should look at.
Hope that answers the question, have a great day!
