TAGC. A pairs with T, G pairs with C.
The opposing base pairs for the sequence ATCG in DNA would be TAGC. Adenine pairs with thymine, and cytosine pairs with guanine in DNA.
Base pairing refers to the pairing of complimentary nitrogen bases, either during DNA replication, or transcription and translation. In DNA, the bases adenine and thymine pair together, and guanine and cytosine pair together. In RNA, the base uracil takes the place of the base thymine. The bases that pair together are said to be complimentary to each other.
The complimentary base for cytosine in DNA is guanine. In RNA, the complimentary base is uracil.
DNA Bases are complimentary as each base only binds to one other (Adenine to Thymine and Guanine to Cytosine).
DNA
The opposite strand in DNA will have bases that pair with the original strand according to the base pairing rules: adenine with thymine and cytosine with guanine. So, if the original sequence is ATCG, the opposite strand will be TAGC.
Complimentary bases are bases that fit together. (Guanine and Cytosine & Adenine and Thymine). A & T are complimentary. G & C are, too. They are bases (the letters) that fit together on a double helix. Complimentary bases are bases that fit together. (Guanine and Cytosine & Adenine and Thymine). A & T are complimentary. G & C are, too. They are bases (the letters) that fit together on a double helix.
Base pair complementarity ensures faithful DNA replication. Remember that a base can only pair with a definite pair and not with just about any base therefore this ensures high fidelity of replication. If guanine can only pair with cytosine the same way that adenine can .only pair with thymine then the copying of the DNA will be accurate.
The molecular weight of a DNA base pair is approximately 650 daltons.

TAGC.
DNA usually comes in a double stranded helix, but if there is only one strand provided, complimentary base pairing occurs. Adenine and Thymine pair, as do Guanine and Cytosine. Given a sequence of DNA, using this, you can find its complementary strand.
