The sequence on the strand of the helix is TACCGGATC.
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.

The two strands in a DNA molecule (the polynucleotides) are complementary to each other. This means that the base sequence in one strand determines the base sequence in the other strand. This happens because of specific base pairing. An adenine in one strand always pairs with a thymine in the other strand, and a cytosine in one strand always pairs with a guanine in the other strand. So if you know the base sequence in one strand of the DNA yoiu can work out the sequence in the complementary strand. See: http://www.phschool.com/science/biology_place/biocoach/dnarep/basepair.htmlDNA strands run anti-parallel from one another, and have a double helix structure. The strands are held together by hydrogen bonds between base pairs that are weak individually, but collectively strong.
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
The sequence on the strand of the helix is TACCGGATC.

no both the double helices aren't the same. the sequences(bases) that are part of one of the helix is sequence complementary to the other strand of DNA.structurally they form the helical pattern, the sequence information is absolutely different.this itself determines the specificity,
A DNA strand is shaped like a 'double helix'.

The whole DNA strand is a double helix.
DNA, and the shape is also known as a double helix.
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.
A double helix
A double helix.
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
