Shown below is a double-stranded bacterial (E. coli) DNA sequence coding for a hypothetical protein. Both strands are shown; the top strand reads 5’ to 3’ left to right, while the bottom strand reads 5’ to 3’ right to left. The nucleotides are numbered 1 to 100.

10.3 (POB) RNA polymerase. How long would it take for the E. coli RNA polymerase to synthesize the primary transcript for E. coli rRNAs (6500 bases), given that the rate of RNA chain growth is 50 nucleotides per second?
RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during transcription. It binds to specific promoter sequences on the DNA, unwinds the DNA helix, and catalyzes the formation of phosphodiester bonds between ribonucleotides.
RNA polymerase The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand. ANA c
23 sie 2022 · DNA transcription, also known as RNA synthesis is the process by which genetic information that is contained in DNA is re-written into messenger RNA (mRNA) by an RNA polymerase enzyme. The synthesized mRNA is transported out of the cell nucleus where it will later on aid in the synthesis of proteins by the mechanism of translation.
a. DNA polymerase moves along the template strand in the 3’ to 5’ direction. b. DNA polymerase requires a primer to initiate replication. c. DNA polymerase forms a covalent bond between a phosphate group and a hydroxyl group. d. Polymerization of DNA for both the lagging and the leading strands is in the 5’ to 3’ direction. e.
