What is the role of RNA polymerase in DNA replication?
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. RNA polymerases have been found in all species, but the number and composition of these proteins vary across taxa.
What is the work 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. This RNA strand is called the primary transcript and needs to be processed before it can be functional inside the cell.
Which of the following is the job of tRNA?
The job of tRNA is to read the message of nucleic acids, or nucleotides, and translate it into proteins, or amino acids. The process of making a protein from an mRNA template is called translation.
What is the job of mRNA quizlet?
mRNA is a messenger of RNA. It carries copies of genetic instructions to the rest of the cell. These instructions tell the cell how to assemble the amino acids for making proteins.
Which is the purpose of transfer RNA quizlet?
What is the function of the transfer RNA? During the construction of a protein, the transfer RNA transfers each amino acid to the ribosome as it is specified by coded messages in mRNA.
What is the function 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.
What is the function of RNA polymerase in protein synthesis?
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).
Why do prokaryotes only have one RNA polymerase?
Bacteria only have a single polymerase to take care of each duty that RNA polymerases have. Where as Eukaryotes (Figure 1) have three separate polymerases, one according to each different type of RNA transcript that is synthesized. Eukaryotes have three distinct polymerases.
