What does it mean to say DNA polymerase reads a template strand to make the complementary strand?
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.

Does RNA polymerase read the DNA template strand in a 5' to 3' direction during transcription?
Yes, RNA polymerase reads the DNA template strand in a 3' to 5' direction during transcription.
During DNA replication a primer attaches to a template strand of DNA and begins a new strand. After the primer has attached an enzyme extends the new strand of DNA by adding nucleotides that correspon?
The enzyme responsible for extending the new DNA strand by adding nucleotides is DNA polymerase. It reads the template strand and adds complementary nucleotides to form a new DNA strand. DNA polymerase can only add nucleotides in the 5' to 3' direction.
How is DNA transcribed into RNA?
During transcription, the enzyme RNA polymerase binds to a specific region of DNA called the promoter. The DNA double helix unwinds, and RNA polymerase reads the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides. This process continues until a termination signal is reached, resulting in the formation of a single-stranded RNA molecule that is complementary to the DNA template.
How does RNA polymerase use DNA?
RNA polymerase reads the DNA template and synthesizes a complementary RNA strand by linking together RNA nucleotides according to the base pairing rules. RNA polymerase moves along the DNA strand in the 3' to 5' direction, synthesizing the RNA transcript in the 5' to 3' direction.
In what direction does RNA polymerase read during transcription?
RNA polymerase reads the DNA template strand in the 3' to 5' direction during transcription.
When is one or both sides of the DNA strand copied in transcriptionI?
In transcription, only one side of the DNA strand is copied. The enzyme RNA polymerase reads the DNA template and synthesizes a complementary RNA strand based on the sequence of the DNA template.

How does DNA template dictate the sequence of the RNA produced?
During transcription the DNA double helix is separated into two individual strands. Each strand may serve as a template for RNA polymerase, which travels along the DNA structure in a 3' to 5' direction. As it progresses down the strand, RNA polymerase synthesizes a pre-messenger RNA strand that is complementary to the sequence on the DNA template. For example if the DNA sequence on the template was 5' ATACA 3', then the pre mRNA sequence synthesized would be 3' UAUGU 5'. (Remember, RNA synthesis utilizes the nucleotide uracil instead of thyamine).
What is the process of making mRNA from a template strand of DNA is known as?
The process of making mRNA from a template strand of DNA is known as transcription. During transcription, RNA polymerase enzyme reads the DNA template and synthesizes a complementary mRNA strand by joining RNA nucleotides together. This mRNA molecule carries the genetic information from the DNA to the ribosomes for protein synthesis.
What enzyme build mrna molecule based on their on code in DNA?
The enzyme responsible for building mRNA molecules based on the genetic code in DNA is called RNA polymerase. RNA polymerase reads the DNA template and synthesizes a complementary strand of mRNA during the process of transcription.
How is RNA transcribed within a cell?
RNA is transcribed within a cell by a process called transcription. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary RNA strand. This RNA strand then serves as a template for protein synthesis.
