What are the phases when a cell's DNA is replicated?
The phases of DNA replication are initiation, where the DNA double helix is unwound and the replication bubble is formed, elongation, where new nucleotides are added to the growing DNA strands, and termination, where replication is completed and the newly synthesized DNA strands are proofread for accuracy.
Does DNA replication take place in the same direction along both strands of the DNA?
No, DNA replication does not take place in the same direction along both strands of the DNA. It occurs in opposite directions on the two strands, known as the leading and lagging strands.
How is DNA replicated in mitosis and meiosis?
During mitosis and meiosis, DNA is replicated by a process called DNA replication. This process involves the unwinding of the DNA double helix, the separation of the two strands, and the synthesis of new complementary strands using the existing strands as templates. This results in two identical copies of the original DNA molecule. In mitosis, DNA replication occurs once, resulting in two identical daughter cells. In meiosis, DNA replication occurs twice, resulting in four daughter cells with half the number of chromosomes as the original cell.
The location where the DNA molecule becomes unzipped is called?
The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.
How is the process of DNA replication affected by the presence of 3' to 5' DNA strands?
The presence of 3' to 5' DNA strands can hinder the process of DNA replication because DNA polymerase, the enzyme responsible for adding new nucleotides to the growing DNA strand, can only add nucleotides in the 5' to 3' direction. This means that the 3' to 5' DNA strands cannot be replicated continuously and may cause delays or errors in the replication process.
What is birectional replication in DNA?
A DNA molecule has two complementary strands, the top (leading) one is 5' to 3' and the bottom (lagging) one is 3' to 5'. The 5' carbon has a phosphate group linked to it and the 3' carbon has a hydroxyl group. During replication, both strands get replicated however DNA strands due to their molecular structure can only be replicated from 5' to 3' so the lagging strand is replicated in 5' to 3' pieces called Okazaki fragments. However, even with this, replication still happens in both strands, even if in the same direction (5' to 3').
Where does replication of the two DNA strands takes place?
in a direction opposite to that of the replication fork

How many individual DNA strands exists after one molecule of DNA has been replicated?
4
How many strands are replicated in DNA replication?
During DNA replication, two strands of the double-stranded DNA molecule are unwound and each strand serves as a template for the synthesis of a new complementary strand, resulting in the formation of two new DNA molecules, each composed of one original strand and one newly synthesized strand.
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
The process of duplicating a DNA molecule?
The process of duplicating a DNA molecule is called DNA replication. This process involves unwinding the double helix structure of the DNA molecule, synthesizing new strands complementary to the original strands, and proofreading for errors. DNA replication ensures that each daughter cell receives an identical copy of the genetic information during cell division.
What is a y-shahped point that results when the two strands of a DNA doble helix separate so that the DNA moecule can be replicated?
Replication Fork
