What does DNA polymerase do MCAT?

DNA polymerase (sometimes called DNA pol) can continuously add nucleotides to create a new daughter strand while the enzyme ligase seals the nucleotides together. It’s important to note that DNA polymerase creates a translated strand that is complementary.

What are the 6 steps of replication?

Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.

What are three facts about DNA replication?

DNA replication occurs during the S-stage of interphase.

  • The structure of DNA is double helix having two complementary strands.
  • As a result of semi-conservative replication,the new helix will be composed of an original DNA strand as well as a newly synthesized strand.

    • What are the steps of DNA replication?

    The first major step for the DNA Replication to take place is the breaking of hydrogen bonds between bases of the two antiparallel strands.

  • One of the most important steps of DNA Replication is the binding of RNA Primase in the the initiation point of the 3′-5′ parent chain.
  • The elongation process is different for the 5′-3′ and 3′-5′ template.
  • In the lagging strand the DNA Pol I – exonuclease – reads the fragments and removes the RNA Primers.
  • The last step of DNA Replication is the Termination. This process happens when the DNA Polymerase reaches to an end of the strands.
  • The DNA Replication is not completed before a mechanism of repair fixes possible errors caused during the replication.

    • What are the problems of DNA replication?

    Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer .

    How does DNA replication is initiated?

    How is DNA replicated? The Initiation of DNA replication. The stage for DNA replication is set in the G1 phase of the cell cycle and DNA is synthesized in the S phase. DNA synthesis. The mechanism of DNA replication is greatly influenced by DNA structure. Okazaki fragment maturation and replication termination. DNA Replication: a mechanobiology perspective.
