Answer:
The virus lacks strcutures to replicate genetic material.
Explanation:
They can replicate it, but don't have structures to do it without the help of a cell. They USE the cell to replicate it but cannot do it themself.

Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
Answer:
Option (B).
Explanation:
The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.
Species A has the DNA sequence TAGCTTAGGGACGG whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.
Thus, the correct answer is option (B).
