Question 1

What are the three fundamental rules of DNA replication?

Answer 1

Semiconservative, bidirectional, semicontinuous

These rules describe how DNA is copied during replication.

Question 2

Define semiconservative replication in DNA replication.

Answer 2

Each strand serves as a template for replication

The two new strands consist of one new strand and its template (old strand).

Question 3

What does bidirectional replication mean?

Answer 3

Replication occurs in both directions from a starting point

This starting point is often referred to as the origin.

Question 4

Explain semicontinuous replication.

Answer 4

One strand is replicated continuously (leading strand)

The other strand is replicated in fragments (lagging strand).

Question 5

Fill in the blank: DNA replication is _______.

Answer 5

semiconservative

Question 6

Fill in the blank: DNA replication is _______ from a starting point.

Answer 6

bidirectional

Question 7

True or False: In DNA replication, both strands are replicated continuously.

Answer 7

False

Only one strand (leading strand) is replicated continuously; the other (lagging strand) is not.

Question 8

What is the significance of the term ‘leading strand’ in DNA replication?

Answer 8

It is the strand that is replicated continuously

The leading strand is synthesized in the direction of the replication fork.

Question 9

What is the role of the template strand in semiconservative replication?

Answer 9

It serves as a guide for synthesizing the new strand

Each new DNA strand is complementary to the template strand.
