1.) The 2 copies of DNA produced by replication in each chromosome remain closely associated until the cell enters prophase of mitosis. 2.) At that point, the chromosomes condense, and the two chromatids in each chromosome become clearly visible. 3.) They separate from each other in anaphase os mitosis, producing 2 cells, each with a complete set of genes coded in DNA.

The first step of DNA replication is to copy part of the DNA sequence into?
The first step of DNA replication is to unwind and separate the two strands of the double helix. This process is initiated by enzymes called helicases. Once the strands are separated, they serve as templates for the synthesis of new complementary strands.
What is the first step of DNA replication?
1. Interphase: replication and growth of the chromosomes occur. 2. Prophase: the chromatin condenses to see the individual chromosomes and centrioles move toward the opposite poles of the cell and spindle fibers grow. 3. Metaphase: the chromosomes align in the center of the cell. 4. Anaphase: spindles attach to the chromosomes and split them in part towards the opposite poles. 5. Telophase: the cell begins to separate into to new daughter cells. 6. Cytokinesis: the nucleus begins to form and the cells are completely cut off from each other.
How does heating and cooling DNA in water resemble the process of DNA replication?
Heating DNA in water denatures it by breaking hydrogen bonds, similar to the initial step in DNA replication where the DNA strands separate. Cooling DNA in water allows the strands to reanneal, akin to the subsequent step in DNA replication where new complementary strands are synthesized.
What major enzyme involved on replication?
DNA polymerase is the major enzyme involved in DNA replication. It is responsible for synthesizing a new strand of DNA complementary to the template strand during replication.
Y shaped regions where the 2 strands of DNA separate?
Replication forks are Y-shaped regions where the two strands of DNA separate during DNA replication. At the replication fork, the DNA helicase enzyme unwinds the double helix structure, creating two single strands that serve as templates for DNA synthesis by complementary base pairing.
What the first step in the replication of DNA the?
mitosis is the very first step in DNA replication my dear friend
Difference between eukaryotic DNA replication and bacterial replication?
Eukaryotic DNA replication is more complex and occurs in the nucleus of the cell, involving multiple origins of replication and coordination with the cell cycle. Bacterial replication is simpler and occurs in the cytoplasm, often with a single origin of replication and a faster rate of replication. Eukaryotic replication also involves telomeres and histones, which are not present in bacterial replication.
What is the first step in replication?
The first step to identifying DNA is to Determine the cell
What is the first step of replication?
The first, and potentially most important, step of DNA replication is unzipping the DNA through enzymes. This allows more nucleotides to be attached to the halves of the DNA, to create more.
Which is the first step to occur during the process of replication?
Separation of the two DNA strands by the action of the Helicase enzyme.
Compare the number of replication forks in prokaryotic and eukaryotic DNA during replication?
Prokaryotic DNA is reproduced with DNA Polymerases replication forks.
DNA replication and transcription occur in the what?
DNA replication and transcription occur in the nucleus of eukaryotic cells. In prokaryotic cells, replication and transcription occur in the cytoplasm.
There is just a single origin of replication in bacterial DNA whereas there are hundreds or perhaps thousands of origins of replication in the DNA of eukaryotic organisms?
true
In the eukaryotic cell where does DNA replication occur?
it occurs in the nucleus...
How does DNA replication differ in prokaryotes and eukaryotes?
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
Where are Nucleotides used for DNA replication in eukaryotic cells made?
nucleus... I believe
