Answer

  1. The HIV capsid contains:

    (b) Single-stranded RNA and reverse transcriptase

  2. Write about the structural components of arrangement.

    The structural components of arrangement in biological systems typically include proteins, lipids, carbohydrates, and nucleic acids. These components form the basis of cellular structures such as membranes, cytoskeletons, and organelles, providing support, protection, and functionality to cells.

  3. Write the composition of the peptidoglycan layer.

    The peptidoglycan layer is composed of long chains of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. These chains are cross-linked by short peptide chains, providing structural strength and rigidity to bacterial cell walls.

  4. What are mesosomes? What are their functions?

    Mesosomes are folded invaginations in the plasma membrane of bacteria. They are thought to increase the surface area of the membrane, aiding in cellular processes such as respiration and cell division. However, their existence and function are debated, as they may be artifacts of cell preparation techniques.
