Is Taq polymerase RNA-dependent?
Taq DNA Polymerase has an intrinsic RNA-dependent DNA polymerase activity (reverse transcriptase activity). However, this activity is very low and is only present under buffer conditions that are completely different from those present during PCR.
Is reverse transcriptase a RNA-dependent DNA polymerase?
Reverse transcriptase is an RNA-dependent DNA polymerase that was discovered in many retroviruses such as human immunodeficiency virus (HIV) and avian myeloblastosis virus (AMV) in 1970. First, RNA-dependent DNA polymerase synthesizes a DNA strand complementary to the RNA template. …
How is the DNA-dependent RNA synthesis called?
Hence, the correct answer is ‘Transcription’
Why is RNA polymerase DNA dependent?
RNA-Polymerase = enzyme of transcription in vivo: The transcription of the genetic information of the DNA-base-sequences into RNA-structure is performed by the DNA-dependent RNA-polymerase [1, 2]. It catalyses the synthesis of RNA in vitro in the presence of a DNA-template and the 4 ribonucleoside-triphosphates.
Where is RNA polymerase used?
RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule.
What is RNA polymerase made up of?
As complex molecule composed of protein subunits, RNA polymerase controls the process of transcription, during which the information stored in a molecule of DNA is copied into a new molecule of messenger RNA.
Is RNA polymerase made of DNA?
In molecular biology, RNA polymerase (abbreviated RNAP or RNApol, and officially DNA-directed RNA polymerase), is an enzyme that synthesizes RNA from a DNA template….RNA polymerase.

Does DNA polymerase unwind DNA?
DNA replication requires unwinding of the complementary two-stranded structure of DNA. DNA Polymerases are one such crucial factor. They are multi-subunit enzymes that participate in the process of DNA replication in the cell. They catalyze the addition of nucleotides onto existing DNA strands.
