Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|_ __|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?

The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'

Explanation:

Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.

In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:

According to this, the complementarity of the strands is:

    5' - T G T A G C T G C G C G T - 3'

    3' - A C A T C G A C G C G C A - 5'

The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.
