Before replication can begin, the following two molecular processes occur:

  1. Helicase binds to DNA
  2. Helicase causes the complimentary strands to separate by breaking the hydrogen bonds between the nucleotide bases, causing the replication bubble to form.

Can you tell the difference between the original and the replicated strand?

Yes, the original strand of DNA is typically referred to as the template strand, while the replicated strand is the newly synthesized strand that complements the original. The original strand contains the original sequence of nucleotides, whereas the replicated strand will have the same sequence but may include errors if replication is not accurate. Additionally, the replicated strand can also differ from the original in terms of post-replication modifications or the presence of newly synthesized nucleotides.


The enzyme amylase un zips or winds the DNA strand?

The enzyme helicase unzips the DNA strand not amylase.


What holds DNA strands apart during replication?

What prevents the wrong nucleotide from being added to the new strand during DNA replication? DNA polymerase 3 and DNA polymerase 1 can become what is known as exonucleases. an exonuclease can go back and "proofread" the replicated DNA and if there is a mistake, then everything beyond that incorrect nucleotide is removed and the DNA polymerase 3 will re-replicate from the bad point on. the protein p53 holds the cell in the G1 and S phase of replication which allows more time for proof reading the replicated DNA


What does semi conservative mean regard to DNA replication?

replicated DNA is made of one old strand and one new strand.


What elongates as DNA unwinds and is replicated continuously?

The leading strand elongates continuously as DNA unwinds and is replicated. DNA polymerase synthesizes the new strand in a 5' to 3' direction, allowing for continuous addition of nucleotides.

Where does Helicase attach to on the DNA strand?

Helicase attaches to the DNA strand at the replication fork, which is the region where the double-stranded DNA is unwound to separate the two strands during DNA replication. Helicase helps to unzip the double helix by breaking hydrogen bonds between the base pairs.
