What happens after DNA replication is completed?


Claire Maxwell   |   Member since 2013  |  10+ Answers Submitted  |  ✔ Verified

The other strand is synthesized in a direction away from the replication fork, in short stretches of DNA known as Okazaki fragments. This strand is known as the lagging strand. Once replication is completed, the RNA primers are replaced by DNA nucleotides and the DNA is sealed with DNA ligase.

In this manner, what happens after DNA replication?

Once completed, the parent strand and its complementary DNA strand coils into the familiar double helix shape. In the end, replication produces two DNA molecules, each with one strand from the parent molecule and one new strand.

Beside above, how does DNA replication stop? Termination requires that the progress of the DNA replication fork must stop or be blocked. Termination at a specific locus, when it occurs, involves the interaction between two components: (1) a termination site sequence in the DNA, and (2) a protein which binds to this sequence to physically stop DNA replication.

Beside this, what happens after a replication fork is formed?

DNA Replication in Prokaryotes: A replication fork is formed when helicase separates the DNA strands at the origin of replication. DNA ligase seals the gaps between the Okazaki fragments, joining the fragments into a single DNA molecule. The replication fork moves at the rate of 1000 nucleotides per second.

What would the chromosome to the right look like after DNA replication?

Before a cell can divide, it must first replicate its DNA so that each of the two daughter cells will receive a complete copy of the DNA. The two identical chromosomes that result from DNA replication are referred to as sister chromatids.

Why does DNA replication occur in the 5 to 3 direction?

These fragments are processed by the replication machinery to produce a continuous strand of DNA and hence a complete daughter DNA helix. DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides.

Why is DNA called the blueprint of life?

DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce. DNA does this by controlling protein synthesis. Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms.

Where does DNA replication occur?

DNA 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.

What is the point of transcription?

Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence.

How long does DNA replication take?

Eukaryotic Replication The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second. At that speed of DNA replication, it would take the cell over a month to copy a chromosome. The fact that it takes only one hour is because of multiple replication origins.

What is the process of transcription?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

Where does DNA replication take place?

DNA replication occurs in the nucleus of eukaryotic cell. By definition, prokaryotic cells do not have nuclei. Therefore, DNA replication occurs in the cytoplasm of a prokaryotic cell. DNA replication is when DNA makes another copy of itself.

What enzymes are 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)

What are the 3 steps in DNA replication?

The three steps in the process of DNA replication are initiation, elongation and termination.Replication Basics. Replication depends on the pairing of bases between the two strands of DNA. Initiation. Elongation. Termination.

What occurs in the process of replication?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. To accomplish this, each strand of existing DNA acts as a template for replication.


Vicky Sawyer   |   Member since 2008  |  ✔ Verified

What is ligase in DNA replication?

DNA ligation. DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another. It is used in cells to join together the Okazaki fragments which are formed on the lagging strand during DNA replication.


Helen Jarvis   |   Member since 2007  |  ✔ Verified

How does DNA replication works?

DNA replication is the process by which DNA makes a copy of itself during cell division. The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.


Judith Bristow   |   Member since 2020  |  ✔ Verified

Why does DNA replication happen?

Explanation: 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!
