The process in which a mRNA molecule forms (by base-pairing) along a part of a DNA molecule is called transcription.

Transcription
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.
DNA replication of one helix of DNA results in two identical helices. If the original DNA helix is calledthe "parental" DNA, the two resulting helices can be called "daughter" helices. Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100% the same due to mutations).DNA creates "daughters" by using the parental strands of DNA as a template or guide. Each newly synthesized strand of DNA (daughter strand) is made by the addition of a nucleotide that is complementary to the parent strand of DNA. In this way, DNA replication is semi-conservative, meaning that one parent strand is always passed on to the daughter helix of DNA.
new DNA strand is made using the original as a template
Through a process called Transcription. Transcription involves a DNA template before it may begin the synthesis of a complementary mRNA strand using RNA Polymerase II in a 5' to 3' direction. When RNA Polymerase II reaches the termination sequence on the DNA template strand, the production of a mRNA (also known as the primary transcript) is completed and the entire transcription complex disassociates.
A complimentary DNA sequence is the genetic code on the partner strand that aligns with and corresponds to (matches) the code on the primary strand. Each nucleotide has a match, A matches T and C matches G, therefore the complimentary sequence for ATCGA is TAGCT.

new DNA strand is made using the original as a template
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
Through a process called Transcription. Transcription involves a DNA template before it may begin the synthesis of a complementary mRNA strand using RNA Polymerase II in a 5' to 3' direction. When RNA Polymerase II reaches the termination sequence on the DNA template strand, the production of a mRNA (also known as the primary transcript) is completed and the entire transcription complex disassociates.

separates the DNA strand and making a complimentary strand
The new strands have new complementary bases on one side and the other is made of the original strand. A strand of DNA has two strands that are complementary to each other in a double helix. When it gets copied one side is used as a template for the new side being added on, the bases cytosine and guanine match up and the bases adenine and thymine match up to each other. For example: If the original DNA strand has this order: 3' G-A-T-A-A-C-C 5' then the new complementary strand has: 5' C-T-A-T-T-G-G 3'
This is called transcription.
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.
The process of generating an mRNA copy of a DNA molecule is called transcription. Here, an enzyme called RNA polymerase opens up the double stranded DNA and begins inserting RNA bases using DNA as the template. Every time the enzyme encounters an Adenine (A), it inserts a Uracin (U) to the growing mRNA strand. When it encounters a cytosine (C), it inserts a Guaning (G) into the growing RNA strand. This is how DNA acts as a template for mRNA
