DNA polymerase
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.

"... errors are corrected in DNA is through the use of the enzyme DNA polymerase. This enzyme is the same one that matches nucleotides that create a new strand to the old strand of a molecule of DNA. After DNA polymerase creates the new molecule of DNA, it checks its work, to make sure that it didn't try to match a nucleotide with its incorrect pair." -taken from last editors paper.
The double strand is separated by an enzyme called helicase. A primer is placed at the 3' end of the template strand. DNA Polymerase III (another enzyme) then adds new nucleotides to the primer, in the 5'-3' direction. The primers are replaced with DNA nucleotides by DNA Polymerase I and joined together by ligase. This is how DNA is replicated.
That depends on the type of protein it needs to make. Bigger the polypeptide, longer the mRNA.
RNA Polymerase is the enzyme responsible for adding RNA nucleotides to make mRNA.
DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
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.

A molecule of RNA contains one strand of nucleotides.

The DNA strand that is copied to make mRNA is the template strand of the gene. This strand serves as a template for the RNA polymerase enzyme to synthesize a complementary mRNA strand during the process of transcription.

To change DNA to mRNA, a process called transcription occurs. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary mRNA strand by matching nucleotides. This mRNA strand carries the genetic information from the DNA and can then be used to make proteins through a process called translation.
It not 1, but four components that make up the strand. These 4 nucleotides are guanine, cytosine, thymine, and adenine (G-C-T-A)
The process of DNA being used to make RNA is called transcription. During transcription, RNA polymerase enzyme unwinds a section of DNA and synthesizes a complementary RNA strand by adding nucleotides according to the base pairing rules. This newly synthesized RNA molecule then serves as a template for protein synthesis during the process of translation.
