Read the following and answer any four questions from 3(1) to 3(v) given below: DNA replication is a complex multistep process that requires enzymes, protein factors and metal ions. DNA replication in eukaryotes occurs in the nucleus during the S-phase of the cell cycle. It is semi discontinuous in eukaryotes. In prokaryotes, replication takes place in the cytoplasm. DNA replication in bacteria occurs prior to fission. Nucleoid or viral chromosome is a single molecule of nucleic acid, it may be linear or circular. Nucleic acid in a virus is either DNA or RNA but never both.

Origin of Replication in Viral DNA
The viral DNA refers to the genetic material present within a virus. Unlike the DNA in eukaryotes and prokaryotes, the viral DNA can exist in either a single-stranded or double-stranded form. Additionally, the viral DNA can be either linear or circular in structure.
Origin of replication
In DNA replication, the process of creating an identical copy of the DNA molecule, the replication begins at specific sites called the origins of replication. These sites serve as starting points for the replication machinery to unwind the DNA strands and initiate the synthesis of new DNA strands.
Number of origins of replication in viral DNA
In the case of viral DNA, the number of origins of replication can vary depending on the type of virus. However, it is important to note that viral DNA never contains both DNA and RNA.
The correct answer to the question is option 'A', which states that there is a single origin of replication in viral DNA. This means that the replication of viral DNA starts at a specific site and proceeds in a unidirectional manner.
Explanation
- Viral DNA can exist in either a single-stranded or double-stranded form.
- Viral DNA can be either linear or circular in structure.
- The replication of viral DNA starts at specific sites called the origins of replication.
- The number of origins of replication in viral DNA can vary depending on the type of virus.
- However, viral DNA never contains both DNA and RNA.
- In the given question, it is mentioned that the viral DNA has a single origin of replication.
- This means that the replication of viral DNA starts at a specific site and proceeds in a unidirectional manner.
- The presence of a single origin of replication ensures that the viral DNA is replicated accurately and efficiently.
Summary
In summary, viral DNA can exist in different forms and structures. The replication of viral DNA starts at specific sites called origins of replication. The number of origins of replication in viral DNA can vary depending on the type of virus. However, viral DNA never contains both DNA and RNA. In the given question, the correct answer is option 'A', indicating that viral DNA has a single origin of replication. The presence of a single origin of replication ensures accurate and efficient replication of the viral DNA.
