WebThe synthesis of RNA is performed by enzymes called RNA polymerases. In higher organisms there are three main RNA polymerases, designated I, II, and III (or sometimes …

WebA) an enzyme that synthesizes RNA primers during DNA replication B) an enzyme that uses RNA as a substrate C) an RNA with enzymatic activity D) an enzyme that synthesizes RNA as part of the transcription process E) an enzyme that catalyzes the association between the large and small ribosomal subunits 17) 18) A transcription unit that is 8000 ... WebDuring this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is … data validation only allow yes or no

WebA - DNA pol 1 RNA primers are removed, and Okaza …. Match the following enzyme with their function: 4 Exonuclease activity removes RNA primer and replaces it with newly synthesized DNA 5 v Synthesizes RNA primers needed to start replication 1. DNA poll 2. DNA pol III 3 Opens the DNA helix by breaking hydrogen bonds between the nitrogenous ... WebUnlike RNA, DNA polymerases cannot synthesize DNA from a template strand. Synthesis must be initiated by a short RNA segment, known as RNA primer, synthesized by Primase in the 5' to 3' direction. DNA … WebDNA primase forms an RNA primer, and DNA polymerase extends the DNA strand from the RNA primer. DNA synthesis occurs only in the 5' to 3' direction. On the leading strand, DNA synthesis occurs continuously. On the lagging strand, DNA synthesis restarts … DNA polymerase only synthesizes DNA in the 5’ to 3’ direction only. The difference … data validation only allow formula
