What is needed for DNA replication select all that apply?
Answer: The things needed for DNA replication are: …
For two identical DNA molecules to be produced, the parent DNA molecule will be unwound by an enzyme known as helicase which breaks the hydrogen bonds between the nitrogenous bases of the two DNA strands thereby separating the two strands..
What is the purpose of DNA replication?
DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
What is DNA replication called?
semiconservative replicationEach strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
What are the steps in DNA?
The synthesis of any macromolecule proceeds in three stages: initiation, elongation and termination. This is true for DNA replication as well. During initiation, DNA synthesis begins at a specific site, called an origin of replication.
What 2 enzymes are used in DNA replication?
1 Answer. DNA primase and DNA polymerase.
Where does DNA replication occur in a cell?
nucleusDNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
What are the steps in DNA replication?
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Is DNA a polymerase?
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. … DNA polymerase adds nucleotides to the three prime end of a DNA strand one nucleotide at a time. When a cell divides, DNA polymerases are needed so that the cell’s DNA can duplicate.
What are the 5 enzymes involved in DNA replication?
Enzymes involved in DNA replication are:Helicase (unwinds the DNA double helix)Gyrase (relieves the buildup of torque during unwinding)Primase (lays down RNA primers)DNA polymerase III (main DNA synthesis enzyme)DNA polymerase I (replaces RNA primers with DNA)Ligase (fills in the gaps)Oct 19, 2014
Which enzyme is not required for DNA replication?
Deoxyribonuclease or DNase is an enzyme that breaks the DNA into nucleotides, i.e. degrades the DNA. DNA polmerase is used to make DNA from nucleotides. RNA polmerase helps in replication. Hence, the correct answer is B.
What is the last step of DNA replication?
5) The last step of DNA Replication is the Termination. This process happens when the DNA Polymerase reaches to an end of the strands.
What is DNA replication Class 10?
DNA replication is the basis of biological inheritance in all living beings. The process gives rise to two identical replicas of the original DNA molecule. … The two copies of the DNA which are synthesized are equally distributed to the two new cells which are formed after cell division.
What are the 6 steps of DNA replication in order?
The complete process of DNA Replication involves the following steps:Recognition of initiation point. … Unwinding of DNA – … Template DNA – … RNA Primer – … Chain Elongation – … Replication forks – … Proof reading – … Removal of RNA primer and completion of DNA strand –More items…
What are the 7 steps of DNA replication?
The series of events that occur during prokaryotic DNA replication have been explained below.Initiation. … Primer Synthesis. … Leading Strand Synthesis. … Lagging Strand Synthesis. … Primer Removal. … Ligation. … Termination.
What is the first step in DNA replication?
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
