When DNA replicates, it is "unzipped", or split in half. Each half will be left with only one half of a base pair (A&T, C&G). To make new DNA, the single helix will act as a template to build the complementary single helix, which will in turn create a new double helix. Since each element of a base pair can only pair with its other half, the helix is a map, or template, for the new helix.
The same concept applies when talking about transcription, or the formation of RNA. However, RNA replaces thymine (T) with uracil (U).
Various DNA polymerases read the DNA template during replication of DNA. Various RNA polymerases read the DNA template during transcription.
The complementary strand of DNA to the template strand TACGGCTA would be ATGCCGAT.
replicated DNA is made of one old strand and one new strand.
DNA is made of of two complimentary strands, the coding strand and the template strand. When DNA is transcribed (made into messenger RNA which can be converted by ribosomes into proteins) the DNA splits open and free nucleotide bases bind to the template strand. DNA is made of T/C/G/A and RNA is made of U/C/G/A nucleotide bases. G and C bind (they are said to be 'complimentary') A and T bind and in RNA U and A bind (so U replaces T.) The newly formed RNA strand (made on the template stand of DNA) is 'complimentary' to the template but the same as the coding strand of DNA. Hence the template is used to produce RNA which is a copy of the coding strand. Either strand of DNA can act as the template/coding strand. Hope that is a little bit helpful!
When the template strand of DNA is read from 3' to 5', DNA synthesis occurs in the 5' to 3' direction.

DNA polymerase is the enzyme responsible for assembling DNA nucleotides into polynucleotides using an existing DNA template. It adds complementary nucleotides to the template strand during DNA replication.
A DNA molecule acts as a template during replication by serving as a guide for the synthesis of a new complementary strand of DNA. The template DNA strand is "read" by DNA polymerase, which adds new nucleotides following base pairing rules (A-T, C-G). This results in the formation of two identical DNA molecules.
The complementary strand of DNA to the template strand TACGGCTA would be ATGCCGAT.
A strand of DNA
DNA remains in the nucleus.
During transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides base-paired with the DNA template. The nucleotides are linked together, forming a single-stranded RNA molecule that is complementary to the DNA template. The process ends when RNA polymerase reaches a termination signal on the DNA template.
Simply means one strand is conserved, as the original template and the other strand in the double stranded DNA is modified.

This is called transcription.
