Transcription--making an RNA template from the DNA strand copy site
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.
This process occurs in the nucleus of a cell. Firstly DNA helicase, will break the hydrogen bonds holding together the two strands of DNA. This exposes the bases on the two strands. RNA polymerase then anneals free nuleotides via phosphodiester bonds, via complementary base pairing to one strand of DNA, known as the template strand. Thus a strand of pre-messenger RNA is built, as the RNA polymerase moves along the DNA strand, the two DNA strands join up behind it. RNA polymerase stops the process of transcription when it reaches stop codons, which tell the enzyme to stop annealing nucleotides. The product is a length of pre-mRNA, which can then leave the nucleus throguh the nuclear pores and undergo splicing to remove introns and then translation.
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.
One is known as the Leading strand, and the other is known as the Lagging strand.

The synthesis of mRNA from DNA is called transcription.
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.

The DNA template strand is used to create mRNA.
The non-coding side of DNA, also known as the non-coding strand or the template strand, serves as a blueprint for producing RNA molecules during the process of transcription. Unlike the coding strand, which has the same sequence as the RNA product, the non-coding strand has a complementary sequence to the RNA molecule, with the nucleotides A, T, G, and C pairing respectively with U, A, C, and G in RNA.

The process that produces mRNA is known as transcription. In this process a single DNA strand is used to make a copy of mRNA.

DNA transcription occurs in the nucleus. It begins at a site known as the promoter, and continues along the DNA template strand that is being transcribed. answer: Nucleus. But to be more exact, promoter.
