Concept explainers

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.

Question

which is true ? After DNA Replication is complete,

1-One copy of DNA has both "old" strands, while the other copy has both "new" strands

2-Each strand on both copies of DNA contains pieces of both "old" and "new" strands

3-Each copy of DNA has one "old" and one "new" strand

Definition Definition Mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of itself. DNA molecules utilize a semiconservative method for replication. DNA replication is the most essential part of biological inheritance and is crucial for cell division during growth and repair of damaged tissues.
