Answer 2

Correct question:

Find the odd one out w.r.t. genetic material

1.TMV

2.QB phage

3. Φx174

4.HIV

Answer:   3. Φx174

Explanation:

The genetic material in the following are as follows

HIV contains  RNA as genetic material.

Φx174 contains DNA as genetic material.

QB phage contains  RNA as genetic material.

TMV contains RNA as genetic material.

Here only Φx174 has DNA as genetic material while others have RNA as genetic material

Hence Φx174 is odd one out.

TMV is a virus that can withstand high temperatures. TMV has a rod-like appearance. The capsid or coat is made up of 2130 protein molecules. The TMV genome is made up of single-stranded RNA with 6400 bases of length.

Bacteriophage ϕ × 174

was the first DNA-based virus whose genome was traced by Fred Sanger and his team in 1977. It has a visual feature of the closed-loop rotation. ϕ × 174

viral particles also began to be synthesized in vitro from synthetic oligonucleotides.

Genetic material refers to the type of nucleic acid present within the viral protein capsule.

The ssDNA or single-stranded DNA (Deoxyribonucleic acid) molecule is composed of a single strand of DNA with the same chemical structure as Double helical DNA. It has a stellate or star shape. It is present in very few viruses such as Bacteriophage ϕ × 174

The human immunodeficiency virus (HIV) is a lentivirus that causes acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans where the ongoing failure of the immune system allows life-threatening diseases and cancer to progress. HIV is made up of two copies of a single-stranded RNA enclosed by a conical capsid. Single-stranded RNA is tightly bound to the nucleocapsid proteins, p7, and enzymes needed to develop virion such as reverse transcriptase, proteases, ribonuclease and integrase.
