DNA acts as a template for two things: # DNA # mRNA transcripts This is possible because each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine (A) always pairs with Thymine (T) Guanine (G) always pairs with Cytosine (C) Note: in RNA, Uracil (U) takes the place of Thymine (T), but still always pairs with Adenine (A). So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: DNA acts as a template because of one fact: each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine always pairs with Thymine (or Uracil in RNA) Guanine always pairs with Cytosine So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: ATTGCAT Looking at the first base, we know that A always pairs with T, and that T always pairs with A for the second base, and so on. Therefore we can reconstruct the complementary strand is: TAACGTA The mRNA transcript would be: UAACGUA This fact is important in two ways. First, when a cell needs to replicate its DNA, it uses an enzyme, DNA Polymerase, to assemble complementary strands by adding nucleotides with the appropriate matching bases along the strand. The result is two identical, complete DNA molecules. Secondly, when the cell needs to build messenger RNA for protein synthesis, it uses an enzyme called RNA Polymerase to assemble the mRNA transcript by adding RNA nucleotides with the complementary matching bases from the DNA strand. The result is an mRNA transcript which will be translated into a protein whose amino acid sequence will reflect the codon sequence of the original DNA strand.
The template DNA refers to the strand of the DNA from which the particular gene is being transcribed. The language of DNA can be interpreted in both the template and non-template strand, but only one of them can correctly transcribe a particular gene.
Template Strand
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
replicated DNA is made of one old strand and one new strand.
the original strand serves as a temple for the new molecule.
The complementary DNA strand template of ATGCCATGG is the basic design structure. It determines how the DNA strand will be constructed and the process in which it is formed.

Template Strand
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
The template strand is used to make a complementary copy. This is a type of DNA strand.
Complementary
replicated DNA is made of one old strand and one new strand.
the original strand serves as a temple for the new molecule.
Lagging strand
The template strand, if reffering to DNA, is the strand of the DNA that is copied to make more DNA.
The complementary DNA strand template of ATGCCATGG is the basic design structure. It determines how the DNA strand will be constructed and the process in which it is formed.
This is typically called the template DNA, which is the anti-sense strand of DNA. The strand that is not transcribed is called the sense strand.
