Which macromolecules are present along with DNA within the cell?

Options

A. Viruses
B. Bacteria
C. Vectors, organelles
D. Lipids, polysaccharides

Explanation

To answer the question "Which macromolecules are present along with DNA within the cell?", we can follow these steps:

### Step 1: Define Macromolecules
Macromolecules are large molecules that are typically composed of thousands of atoms. They are formed by the polymerization of smaller units called monomers. The main types of macromolecules found in cells include proteins, nucleic acids (like DNA and RNA), carbohydrates (like polysaccharides), and lipids.

### Step 2: Identify the Macromolecules Present in Cells
In a cell, alongside DNA, several macromolecules are present:
- **Proteins**: These are made up of amino acids and play various roles in the cell, including structural support, catalyzing biochemical reactions, and regulating cellular processes.
- **RNA**: Ribonucleic acid is involved in protein synthesis and gene regulation.
- **Polysaccharides**: These are complex carbohydrates that serve as energy storage (like starch and glycogen) and structural components (like cellulose in plant cell walls).
- **Lipids**: These are hydrophobic molecules that include fats, oils, and phospholipids, which are essential for forming cell membranes.

### Step 3: Conclusion
Thus, the macromolecules present along with DNA in a cell are:
1. Proteins
2. RNA
3. Polysaccharides
4. Lipids

### Final Answer
The macromolecules present along with DNA within the cell are proteins, RNA, polysaccharides, and lipids.
