**Template Strand: The DNA strand that is transcribed during transcription is called the template strand.**

During the process of transcription, DNA serves as a template for the synthesis of RNA. The DNA molecule consists of two strands that are complementary to each other. These two strands are known as the template strand and the coding strand.

The template strand is the strand of DNA that is used as a template for the synthesis of RNA. It is also sometimes referred to as the antisense strand because its sequence is complementary to the RNA molecule that is transcribed from it.

**DNA Dependent RNA Polymerase: The enzyme responsible for catalyzing transcription is DNA dependent RNA polymerase.**

DNA dependent RNA polymerase is an enzyme that plays a crucial role in the process of transcription. It binds to the DNA double helix and moves along the template strand, synthesizing a complementary RNA molecule. It catalyzes the formation of phosphodiester bonds between the nucleotides, thus elongating the growing RNA chain.

**Transcription Process: How DNA dependent RNA polymerase catalyzes transcription**

1. Initiation: DNA dependent RNA polymerase recognizes and binds to a specific DNA sequence called the promoter region. The promoter region is located upstream of the gene that is going to be transcribed. Once bound, the RNA polymerase unwinds a small portion of the DNA double helix, exposing the template strand.

2. Elongation: The RNA polymerase moves along the template strand in a 3' to 5' direction. It reads the DNA sequence and catalyzes the formation of phosphodiester bonds between the nucleotides of the growing RNA chain. The RNA molecule is synthesized in a complementary manner to the template strand, following the base pairing rules (A-U, G-C).

3. Termination: Transcription continues until the RNA polymerase encounters a termination signal, which is a specific DNA sequence that signals the end of the gene. At this point, the RNA polymerase detaches from the DNA template, and the newly synthesized RNA molecule is released.

**Summary:**
During transcription, DNA dependent RNA polymerase catalyzes the synthesis of RNA using the DNA template strand. The template strand is the DNA strand that is transcribed, and the RNA polymerase binds to a specific DNA sequence called the promoter region to initiate transcription. The RNA polymerase moves along the template strand, synthesizing a complementary RNA molecule in a 3' to 5' direction. Transcription continues until a termination signal is encountered, at which point the RNA polymerase dissociates from the DNA template and the RNA molecule is released.
