Question

Which type of DNA is found in bacteria?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Bacterial DNA structure
	**Related Topics**: DNA types, Prokaryotic cells
	**Prerequisites**: Basic knowledge of DNA structure and cell types
## SOLUTION PATHWAY
**Given Information**:
	 The question asks for the type of DNA found in bacteria.
**Method & Steps**:
	1. Recall the characteristic DNA structure found in bacteria.
		Reasoning: Bacteria are prokaryotes and their DNA is typically found as a circular chromosome.
		Formula/Rule: None applicable.
	2.  Match the recalled information to the options.
		Working: Bacteria have circular DNA that is not bound by a membrane.
	3. Select the correct option.
		Result: Circular free DNA is the correct answer.
		Verification: The answer matches the known characteristic of bacterial DNA.
 ## OPTION ANALYSIS
[A] :x: Helical DNA is a general characteristic of DNA but not specifically of bacterial DNA.
[B] :x: Membrane bound DNA is a characteristic of eukaryotic cells.
[C] :x: Straight DNA is not the common structure of bacterial DNA.
[D] ✓: Circular free DNA is the typical structure of bacterial DNA
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing eukaryotic and prokaryotic DNA structures.
			[How to avoid]: Remember that eukaryotes have linear DNA in a nucleus, while prokaryotes have circular DNA in the cytoplasm.
	**Quick Tips**:
		1.[Helpful shortcut]: Think of bacteria as simple cells with simple DNA - circular and not in a membrane-bound nucleus.
