Answer:
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:
- <em>Adenine is complemented with Thymine.
</em>
- <em>Guanine is complemented with Cytosine.
</em>
According to this, the complementarity of the strands is:
<em> 5' - T G T A G C T G C G C G T - 3'</em>
<em> 3' - A C A T C G A C G C G C A - 5'</em>
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.
