What is the function of RNA polymerase?
RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
What is the role of RNA Primase?
Primase is an enzyme that synthesizes short RNA sequences called primers. Since primase produces RNA molecules, the enzyme is a type of RNA polymerase. Primase functions by synthesizing short RNA sequences that are complementary to a single-stranded piece of DNA, which serves as its template.
What are two functions of RNA polymerase?
RNA polymerases transcribe the information in DNA into RNA molecules that have a variety of functions, including messenger RNA, transfer RNA, ribosomal RNA (for protein synthesis), ribozymes (for catalysis), and microRNA (for regulation of gene expression).
What is a RNA polymerase and what are its features?
A RNA polymerase (RNAP), or ribonucleic acid polymerase, is a multi subunit enzyme that catalyzes the process of transcription where an RNA polymer is synthesized from a DNA template. Some RNAP molecules can catalyze the formation of a polymer over four thousand bases in length every minute.
What is the role of RNA polymerase quizlet?
What is the function of RNA Polymerase? RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.
Does RNA primer have thymine?
In RNA, adenine is complementary to uracil, and guanine remains complementary to cytosine. Keep in mind that there is no uracil in DNA and no thymine in RNA.
What are the features of RNA polymerase?
A RNA polymerase (RNAP), or ribonucleic acid polymerase, is a multi subunit enzyme that catalyzes the process of transcription where an RNA polymer is synthesized from a DNA template. The sequence of the RNA polymer is complementary to that of the template DNA and is synthesized in a 5’→ 3′ orientation.
What is RNA polymerase simple?
Definition of RNA polymerase : any of a group of enzymes that promote the synthesis of RNA using DNA or RNA as a template.
