A student analyzed a viral genome and found that the genome had the following nucleotide composition.
lapo4ka [179]

Answer:

Option A) Double-stranded DNA

Explanation:

Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.

Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.

Thus, the structure of the viral genome is Double-stranded DNA.

The regression equation is:

y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

<span> <span> <span> Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058

Inserting the values,
<span><span></span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748

y = 1.15 + 0.0629508 + 0.0060606 + 0.935748

y = 1.3125862

Answer:

x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
