What is the role of the enzymes in the DNA replication process?
DNA polymerase enzymes bind to and dissociate from template DNA repeatedly during the replication or repair process. The number of synthesized nucleotides added by the DNA polymerase per one binding event is defined as processivity.
What are the two main functions of the enzyme DNA polymerase during DNA replication?
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule.
What are the steps for transcription?
Transcription involves four steps:Initiation. The DNA molecule unwinds and separates to form a small open complex. Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule. Termination. In prokaryotes there are two ways in which transcription is terminated. Processing.
What is transcription and where does it occur quizlet?
Transcription occurs in the nucleus. mRNA, or Messenger RNA, is the copy of the DNA that transfers the information from the nucleus to the ribosomes.
What is the process of transcription?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
