Write a short story describing the application of the system of classification of living creatures
Citrus2011 [14]
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.

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.
