C - cytosine
The complementary base pairs in DNA are adenine (A) with thymine (T), and cytosine (C) with guanine (G).
Complementary base pairs are nucleotide bases in DNA that always bond together in a specific way: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). An example of complementary base pairs is A-T and C-G.
The correct complementary base pairs in DNA are adenine (A) with thymine (T), and cytosine (C) with guanine (G).
The base sequence complementary to CGAC in a DNA molecule is GCTG. In DNA, cytosine (C) pairs with guanine (G), and adenine (A) pairs with thymine (T), so you would replace each base with its complementary counterpart. Therefore, C pairs with G, G pairs with C, A pairs with T, and C pairs with G.
The base sequence for the complementary DNA would be GCA AT. Since DNA strands are complementary, the bases pair as follows: A with T, T with A, C with G, and G with C.
CCGTAGGCC is a sequence of DNA base pairs. It represents the complementary DNA strand to the original sequence GGCTACGG, where each base pairs with its complementary base (A with T and C with G).
If a G is inserted as the first base on side A, then the complementary base on side B would be C (G pairs with C). The order of bases would be G-C followed by the existing sequence in side A.
The base sequence on the complementary DNA strand will be GCATCC. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, for each base in the original sequence CGTAGG, the complementary bases are as follows: C pairs with G, G pairs with C, T pairs with A, A pairs with T, G pairs with C, and G pairs with C again.
In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between cytosine (C) and guanine (G).
The complementary DNA base sequence for AACT is TTGA. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, each base in the original sequence is replaced by its complementary base.
ATAGCC is complementary to the base sequence TATCGG.
In RNA, the unique complementary base pairing is between adenine (A) and uracil (U), and between guanine (G) and cytosine (C).
