Which of the following is a double stranded DNA virus?
A. sars - cov2
B. jaers - cov
C. Human Papillomavirus
D. Rhinovirus
Answer (2)
SARS-CoV-2 is a single-stranded RNA virus.
SARS-CoV is a single-stranded RNA virus.
Human Papillomavirus (HPV) is a double-stranded DNA virus.
Rhinovirus is a single-stranded RNA virus.
Therefore, the answer is C: Human Papillomavirus. C
Explanation
Understanding the Problem We need to identify which of the listed viruses is a double-stranded DNA virus. The options are: SARS-CoV-2, Jaers-CoV, Human Papillomavirus, and Rhinovirus.
Researching Virus Types Let's research the genetic structure of each virus to determine if it has single-stranded DNA, double-stranded DNA, single-stranded RNA, or double-stranded RNA.
Identifying Virus Types
SARS-CoV-2 is a single-stranded RNA virus.
Jaers-CoV (likely a typo for SARS-CoV) is a single-stranded RNA virus.
Human Papillomavirus (HPV) is a double-stranded DNA virus.
Rhinovirus is a single-stranded RNA virus.
Determining the Answer Based on our research, Human Papillomavirus (HPV) is the only double-stranded DNA virus among the options.
Examples
Understanding the genetic structure of viruses is crucial in developing effective vaccines and antiviral treatments. For example, knowing that HPV is a double-stranded DNA virus allows scientists to target its replication mechanisms specifically, leading to the creation of vaccines that prevent HPV-related cancers. Similarly, understanding that SARS-CoV-2 is an RNA virus helps in designing antiviral drugs that disrupt its RNA replication process. This knowledge is vital in combating viral infections and improving public health.
The double-stranded DNA virus among the options is Human Papillomavirus (HPV). Other viruses listed are either single-stranded RNA viruses. Thus, the correct answer is C: Human Papillomavirus.
