What produces cells with identical DNA?

Mitosis
Mitosis produces two daughter cells that are genetically identical to each other, and to the parental cell. A diploid cell starts with 2N chromosomes and 2X DNA content.

What is a identical DNA molecule called?

In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes. Chromatid pairs are normally genetically identical, and said to be homozygous.

Are the two DNA molecules genetically identical?

DNA replication is the process in which the double stranded DNA molecule duplicate two identical DNA molecules. Each cell divides to generate two identical daughter cells (genetically) as the parent cell.

Why are the two cells produced by mitosis genetically identical?

The two cells are genetically identical because during S phase an exact copy of each DNA molecule was created. … Mitosis ensures that each new cell receives one of the two identical sister chromatids. Thus, the newly formed cells will contain identical daughter chromosomes.

Why does mitosis create genetically identical cells?

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. … These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

Why does the DNA produced through replication need to be identical?

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Which enzyme is used to join together two different types of DNA molecules?

DNA ligase
Which enzyme is used to join together two different types of DNA molecules? Explanation: DNA ligase is used to join two different types of DNA molecules, thus giving rise to a recombinant molecule that can be cloned inside a suitable host to facilitate the gene expression.

Why does the DNA molecule need to make identical copies of itself?

DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. … The enzyme DNA Helicase is involved in breaking these bonds. The two single strands of DNA then each serve as a template for a new stand to be created.

What are the products of the replication of one DNA molecule?

The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides.

When DNA separates into two strands the DNA would most likely be directly involved in what process?

DNA replication
Correct answer:

Explanation: DNA replication involves the separation of the two original DNA strands. Both of these strands are then replicated using DNA polymerase.

What keeps the two DNA strands separate during replication?

helicase
First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.

When one DNA molecule is replicated the second molecule is identical or nearly identical to the first DNA molecule Why does this occur?

DNA replication is semi-conservative. This means that each new molecule of DNA contains one strand of the parent molecule and one complementary strand that is newly synthesized (daughter strand). Hence two newly generated molecules remain similar to the parent DNA molecule.

What is the product of DNA replication quizlet?

The final product of DNA replication is: two DNA molecules, each of which contains one new and one old DNA strand. The information carried by DNA is incorporated in a code specified by the: specific nucleotide sequence of the DNA molecule.

What is the end product of replication?

The outcome of DNA replication is two DNA nearly identical DNA double helix molecules. Each DNA is made up of one DNA strand from the original DNA and a newly created strand.

When one DNA molecule is copied to make two DNA molecules each new DNA molecule contains?

When one DNA molecule is copied to make two DNA molecules, each new DNA contains 100% of the parent DNA. DNA replication uses each strand of a DNA molecule as a template for the creation of a new strand. You just studied 10 terms!

Is the second DNA molecule identical to the first?

when one DNA molecule is replicated, the result is two DNA molecules. … It is identical or nearly identical to the first DNA molecule. What is the role of enzymes is the DNA replication process? Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.

Are the two double stranded DNA molecules identical or different explain?

Each new double strand consists of one parental strand and one new daughter strand. This is known as semiconservative replication. When two DNA copies are formed, they have an identical sequence of nucleotide bases and are divided equally into two daughter cells.

What makes up the rungs of the DNA molecule?

It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. … Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder.
