How does the absence of proofreading ability for RNA polymerase affect the rate of error in the transcription process in comparison with DNA replication . Introduction: To convert genotype to phenotype , the conversion of information saved in the DNA to proteins is required. The central dogma describes the flow of information is one direction (DNA to RNA, and RNA to proteins). The flow of information from DNA to RNA is referred to as transcription, while the flow of information from RNA to protein is referred to as translation.

Which of the following features is common to both DNA replication and RNA transcription? Both RNA and DNA polymerase form a sugar-phosphate bond between the 3' hydroxyl and the 5' phosphate. Both RNA and DNA polymerase require oligonucleotide priming. Both RNA and DNA polymerase incorporate deoxyribonucleotides into the growing sequence. Both RNA and DNA polymerase initiate at promoter sequences. Both RNA and DNA polymerase have extensive proofreading editing.

The RNA polymerase is only using one strand of DNA as a template, and only transcribes specific sequences. In eukaryotes, how does the RNA polymerase “know” which strand to use as a template and precisely where to initiate transcription? Explain your answer, including any relevant DNA sequences/structures and proteins needed for the process.
