Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)
-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

Being or used to produce an organism or cell of one species into which one or more genes of another species have been incorporated
A nucleus is the central and the most important part of an object, movement, or group.
It is found in plant and animal cells and an atom.
Hope this helped :)
Have a great day
The answer is B) It does not show all the phases of mitosis.
The absence of a particular trait does not exclude a species from a particular clade that possesses that trait because physical attributes of the species is not the basis of the groupings in the clade.
Cladistic groupings uses the evolutionary relationships among the species as its basis in grouping rather than its shared physical traits. These evolutionary relationships are called apomorphies or a set of unique features shared by all organisms in the group but not found in the distant ancestors.
