Final answer:
G and C are present in both DNA and RNA.
Step-by-step explanation:
True. G and C are bases that are present in both DNA and RNA. Both DNA and RNA are nucleic acids that consist of a chain of nucleotides, with each nucleotide containing a nitrogenous base. The bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T), while in RNA, thymine is replaced with uracil (U). Therefore, G and C are common bases in both DNA and RNA.
