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.
ATAGCC is complementary to the base sequence TATCGG.

A binds with T, C binds with G. Therefore the complementary DNA sequence will be GTCAATCG. The complementary RNA would be CAGTTAGC. The OH means it is the 3' end - so the complementary strand would be 5' at the same spot.
The complementary base pairing of nucleotides is what ensures accurate replication of the DNA molecule during each PCR cycle. This pairing dictates that adenine pairs with thymine and cytosine pairs with guanine, which allows for the faithful duplication of the original DNA sequence.
During DNA replication, a complementary nucleotide is added to each exposed base on the original DNA molecule. This process ensures the formation of two identical DNA molecules.
The base sequence of cDNA is complementary to the mRNA molecule from which it is synthesized. This means that the cDNA will have the same sequence as the mRNA, except that thymine in DNA is replaced with uracil in RNA.

The complementary sequence for a DNA sequence is formed by replacing each nucleotide with its complementary base. For the given sequence "atgcccgggtgtcgtagttga," its complementary sequence would be "tacgggccacagcatcaact."
ATAGCC is complementary to the base sequence TATCGG.
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).

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.
A binds with T, C binds with G. Therefore the complementary DNA sequence will be GTCAATCG. The complementary RNA would be CAGTTAGC. The OH means it is the 3' end - so the complementary strand would be 5' at the same spot.
The order of bases in the second strand of a DNA molecule is complementary to the first strand, following the base pairing rules (A with T, C with G). So, if the first strand has the sequence ATCG, the second strand would have the sequence TAGC.
