Helicase proceeds to break hydrogen bonds and separates the polynucleotide chain. Simultaneously, primase also attaches to each strand and creates a starting point where replication can begin, known as a primer. Once the primer is attached on a single, unwound polynucleotide strand, DNA polymerase ...
DNA Replication: DNA replication occurs both when a cell is getting ready to divide and when it needs to make new plasmids, mitochondria, or chloroplasts. In eukaryotes, DNA replication happens on both the leading strand and the lagging strand and requires the presence of RNA primers. ...
What is the purpose of DNA replication? What is the purpose of DNA helicase in the DNA replication process? Why is DNA replication necessary? How is transcription different from replication? How is replication different from transcription?
DNA Structure Chargaff’s Rule DNA Replication Function of DNA Why DNA is called a Polynucleotide Molecule? Read on to explore DNA meaning, structure, function, DNA discovery and diagram in complete detail. What is DNA? “DNA is a group of molecules that is responsible for carrying and transmi...
RNA primer synthesis is facilitated by transcription factors and proteins including TFAM,POLRMT, and TFB2M. DNA polymerase γ catalyzes strand synthesis, while Twinkle helicase unwinds DNA and TOP1MT relaxes supercoiled DNA. SSBP1 stabilizes single-stranded regions. RNA primers are r...

Answer and Explanation:1 A carrier molecule is a protein that helps transport a substance or electrons across a barrier. Carrier proteins usually allow the transport of polar... Learn more about this topic: Carrier Proteins | Definition, Functions & Examples ...
Werner syndrome (WS) is a rare autosomal recessive disorder characterized by genomic instability and the premature onset of several age-associated phenotypes. The protein defective in WS patients (WRN) is a helicase/exonuclease involved in DNA replication, repair, telomere maintenance, and transcription...
HGPS cells show defects in cellular proliferation and premature senescence, suggesting that advanced ageing of tissues may be the result of impaired growth or decreased replicative potential at the cellular level. Multiple progeria models are associated with enhanced DNA damage, implicating this form of...
Explain the role of DNA polymerases in replication. What are the role of DNA polymerase and RNA polymerase? What is the role of DNA polymerase III? How are the hydrogen bonds important in the replication of DNA? What is helicase? Describe its role in DNA replication. What role do single-...
