A single strand of DNA helix has the code CGCTAA. Which would be the complementary code on the other strand of the helix?
Yakvenalex [24]

The correct answer is option 4, that is, GCGATT.  

Complementary strand refers to either of the two chains, which forms a double helix of DNA, with corresponding positions on the two chains comprising of a pair of complementary bases. It is a section of one nucleic acid, which is bonded to another by an alignment of base pairs.  

In nature, complementarity refers to the base principle of DNA transcription and replication as it is a characteristic shared between the two RNA or DNA sequences, such that when they are arranged antiparallel to each other, the nucleotide bases at each position in the sequences will be complementary.
