What does semi-conservative replication of DNA mean?(1 point)

Responses

Both strands of the DNA molecule are completed conserved.
Both strands of the DNA molecule are completed conserved.

One strand of the DNA molecule is completely conserved, while the other is completely replaced.
One strand of the DNA molecule is completely conserved, while the other is completely replaced.

Each newly synthesized DNA molecule consists of one original strand and one newly synthesized strand.
Each newly synthesized DNA molecule consists of one original strand and one newly synthesized strand.

DNA replication occurs without any conservation of the original DNA strands.

The correct response is:

Each newly synthesized DNA molecule consists of one original strand and one newly synthesized strand.

This describes semi-conservative replication, where each DNA double helix contains one old (parental) strand and one new (daughter) strand after replication.
