How many copies of a DNA molecule result from two replications of a single DNA molecule?
Four copies of a DNA molecule result from two replications of a single DNA molecule. This is because each replication results in two identical daughter molecules.
What structure that contains identical DNA copies and is formed during DNA replication?
The structure that contains identical DNA copies formed during DNA replication is called a "sister chromatid." After DNA replication, each chromosome consists of two sister chromatids, which are joined at a region called the centromere. These identical copies ensure that each daughter cell receives an exact copy of the genetic material during cell division.
Why is DNA copied in the process of replication?
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
What happens at a DNA replication for during replication?
The hydrogen bonds that hold the two DNA strands together are broken. This creates two prongs and each are made up of a single strand of DNA that creates two new partners for the two strands (because they add nucleotides).
What is the process called when a bacterial cell makes copies of its DNA then divides making two identical cells?
Mitosis
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
Sister chromatids - two copies of the same DNA joined at the centromere.
If you compare the original DNA to the two copies that are made after replication occurs what would you find?
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
What the two copies of a chromsomes are called?
The two copies of a chromosome are called sister chromatids. They are identical copies formed during DNA replication and are connected at a region called the centromere. Sister chromatids are separated during cell division to ensure that each daughter cell receives an identical set of chromosomes.
The two chromatid arms on a chromosome are what?
The two chromatid arms on a chromosome are known as sister chromatids, which are genetically identical copies created during DNA replication. Sister chromatids are joined at the centromere and are separated during cell division.
During cell division each chromosomes makes an?
During cell division, each chromosome makes a copy of itself through a process called DNA replication. This creates two identical copies of the chromosome, which are then separated into two new cells during mitosis.
When mitosis is complete the two new cell that are formed does it contain identical copies of Dna?
Yes, after mitosis is complete, the two new cells formed will each contain identical copies of DNA. This is because during the S phase of the cell cycle, the DNA is replicated so that when the cell divides, each daughter cell receives a complete and identical set of genetic material.
How many coiled DNA molecules has an S phase have at the end?
At the end of the S phase, each DNA molecule is duplicated and consists of two coiled sister chromatids. This results in each chromosome having two identical copies of DNA.
