Question

What DNA/RNA/protein(s) is/are involved in the following processes in... DNA Replication Transcription - Prokaryotes Transcription - Eukaryotes What serves as the template? Unwinding of DNA Initiation Elongation What direction does elongation occur? Termination What is the end product of this process? How many strands? Processing after?

Answer 1

DNA Replication What DNA/RNA Protein are involved in the following Transcription Prokaryotes Transcripts Eukaryotes Non- what serves as Template Antisense Strand (315) of ONA Non-coding strand of coding DNA DNA Helicase RNA Unwinding of DNA Initiation DNA strand RNA Polymerase Polymerase RNA DNA Polymerase Primase Helicases Polymerase Transcription actors. Elongation RNA RNA DNA ligases. DNA Polymerase Topoisomerase SSB Proteins - Polymerase Polymerase Direction 51-31 Direction 51-31 Direction 51-31- Leading strand 31-5 - Lagging Strand [Okazaki Fragments

Termination Poly(A) Ter Protein Tus Proteini Signal; Rho-Dependent or Rho- Independent Proteins Downstream Terminator sequence RNA Endproduct. strands - Two DNA molecules One new and one old strand (Semi-conservative Polycistronic M-RNA'S [many RNA'S with different functions molecules- MRNA, E-RNA. n-RNA Processing after Parent strand & its complementary DNA coils to a double helix Rho-protein collides with Polymerase - Rho releases M-RNA from transcription splicing pre-mRNA's; 5 capping; 3 addition of Poly-A tail bubble.
