Biofilms are complex structures composed of various biological polymers. Which of the following is a key component of biofilms, beyond exocellular polysaccharides? A) Deoxyribonucleic acid (DNA) and proteins, contributing to the biofilm's architecture and function. B) Lipopolysaccharides (LPS) that contribute to the biofilm's structural rigidity. C) Peptidoglycans forming a mesh-like network throughout the biofilm matrix. D) Phospholipids that create a hydrophobic barrier, preventing water penetration into the biofilm.
Understand the Problem
The question is asking which component, beyond exocellular polysaccharides, is a key part of biofilms, with multiple options provided for selection. This involves understanding the composition and structure of biofilms.
Answer
Deoxyribonucleic acid (DNA) and proteins.
The final answer is Deoxyribonucleic acid (DNA) and proteins, contributing to the biofilm's architecture and function.
Answer for screen readers
The final answer is Deoxyribonucleic acid (DNA) and proteins, contributing to the biofilm's architecture and function.
More Information
DNA and proteins play crucial roles in the structural and functional aspects of biofilms, alongside exocellular polysaccharides. Extracellular DNA (eDNA) contributes to the stability and architecture of biofilms.
Tips
A common mistake is to overlook the variety of biological polymers in biofilms and assume only polysaccharides are significant. Remember that biofilms are diverse structured entities.
