Interpretation:
The composition of [T] and [C] for a double-helical strand of DNA molecules if
Concept introduction:
According to base pair rule, (A) is always equal to (T) and (G) is always equal to (C) for a double strand helix of DNA that is
Adenine (A) =Thymine (T) and
Guanine (G) = Cytosine (C)
Interpretation Introduction
(b)
Interpretation:
The composition for [A], [T], [G], and [C] of complementary strand should be determined.
Concept introduction:
According to the rule, there are four nucleotides in DNA; they are Adenine (A), Cytosine (C), Guanine (G), and Thymine (G).
Base pair in DNA are A=T and G=T.
