<u>Explanation:</u>

Deoxyribonucleic acid is the one which carries the genetic information from the parent to the offspring.  During DNA replication one strand of DNA replicates to produce another strand.        

The DNA molecule have a anti-parallel structure and the two strands run in opposite direction. If in one strand in a segment of a gene has the base sequence TGCTTA the complementary sequence of nucleotides found on the other strand of DNA will be ACGAAT.
