The diagram represents a model of DNA replication.

The diagram shows a strand of DNA being replicated.

What can you conclude about DNA replication?

A. Both original strands are replicated in the same direction.
B. The two original strands are replicated in opposite directions.
C. Only one complementary strand is replicated.
D. Each original strand is broken apart and nucleotides are reused

Although there is no attachment, the best answer would be option B.

DNA replication occurs in opposite directions along a strand of DNA.

The leading strand is replicated continuously in the 5' to 3' direction towards the replication fork.

The lagging strand is replicated discontinuously in the 5' to 3' with segments of DNA known as Okazaki fragments.

b.   The two original strands are replicated in opposite directions.

Explanation:

Look at the diagram You will see why B is right

Also You know I am right >=}

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
