DNA strand which is formed continuously in 5’  $ 	o $  3’ direction is called

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
**Primary Concept**: DNA Replication
**Related Topics**: Leading strand, Lagging strand, DNA Polymerase, Direction of Synthesis
**Prerequisites**: Basic understanding of DNA structure and replication process.
## SOLUTION PATHWAY
**Given Information**:
* Question asks about the DNA strand formed continuously in the 5' to 3' direction
**Method & Steps**:
 1. Recall the definition of leading and lagging strands during DNA replication.
    Reasoning: During DNA replication, one strand (leading strand) is synthesized continuously in the 5' to 3' direction, while the other strand (lagging strand) is synthesized discontinuously in fragments (Okazaki fragments).
    Formula/Rule:  DNA polymerase can only add nucleotides to the 3' end of a growing strand.
 2. Identify the strand that is formed continuously in the 5' to 3' direction.
    Working: The leading strand is synthesized continuously in the 5' to 3' direction.
 3. Select the correct answer.
   Result: The correct answer is the leading strand.
  Verification: This is a fundamental fact about DNA replication.
 ## OPTION ANALYSIS
[A] :x: Lagging strand is synthesized discontinuously.
[B] ✓: Leading strand is synthesized continuously in the 5' to 3' direction.
[C] :x: Template strand is the strand that is being copied.
[D] :x: Stranded strand is not a defined term in DNA replication.
 ## LEARNING AIDS
**Common Mistakes**:
1. Confusing leading and lagging strands: Understand that leading strand synthesis is continuous and lagging is discontinuous.
2. Forgetting the 5' to 3' direction: DNA polymerase always adds nucleotides to the 3' end.
**Quick Tips**:
1. Remember 'leading' as 'leading the way' for continuous synthesis.
2. Visualize the replication fork: Leading strand goes in the same direction as the fork movement, lagging strand in the opposite direction.
