Group II viruses violate the Central Dogma. Is this statement above true or fals

Question

Group II viruses violate the Central Dogma.

Is this statement above true or false and why?

Please indicate if you think the highlighted statement above is True or False, AND you must pick one of the rationals for your choice from the list presented below. Your answer should follow the form of the word True or False immediately followed by a number.

For example, False3 would mean you think the statement above is false, because Group II Viruses use a DNA genome as a template for DNA, which is then transcribed to mRNA. The Central Dogma is DNA -> RNA -> Protein. Group II viruses use a DNA -> DNA -> RNA -> Protein pathway

1. Group II Viruses still use a DNA genome as a template for anti-sense DNA, which is then used as a template for RNA, which is then translated to proteins. This is still DNA -> RNA -> Protein.

2. Group II Viruses use an RNA genome as a template for for proteins.

3. Group II Viruses use a DNA genome as a template for DNA, which is then transcribed to mRNA. The Central Dogma is DNA -> RNA -> Protein. Group II viruses use a DNA -> DNA -> RNA -> Protein pathway.

4. Group II Viruses use an RNA genome to synthesize DNA, which is then used to synthesize mRNA, which is then used to synthesize proteins. This is still DNA -> RNA -> Protein.

Explanation / Answer

False 1

Group II viruses contains single stranded DNA as their genetic material. These viruses are known to infect plants. After infecting the host cell, it uses the host enzymes to synthesize complementary or antisense strand, hence converting ssDNA to dsDNA. The viral genes are then transcribed by host RNA polymerase and then translated to viral proteins. it follows the order

DNA-> RNA->Protein

Hence this virus does not violates central dogma.
