This document summarizes prokaryotic DNA replication. It describes prokaryotic replication as the process by which a circular, double-stranded DNA molecule in prokaryotic cells is copied to produce two identical molecules. The key steps are initiation at a single origin of replication, elongation of DNA strands by DNA polymerases, and termination resulting in two circular chromosomes. The replication occurs rapidly in the cytoplasm and requires enzymes including DNA polymerases I and III.
replication of DNA to form two daughter DNA molecules, basis of cell division and transfer of genetic information from one generation to other generation
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance. The cell possesses the distinctive property of division, which makes replication of DNA essential.
Replication Introduction , DNA replicating Models , Meselson and Stahl Experiments , Circuler Model of DNA replication , Replication in Prokaryotes , Replication In Eukaryotes , Comparison Between Prokaryotes and Eukaryotes Replicaton and PCR (Polymerease Chain Reaction)
Here is the process of formation of progeny DNA from Parental DNa. The process is described here briefly. DNA, abbreviation of deoxyribonucleic
acid, organic chemical of
complex molecular structure that is found
in all prokaryotic and eukaryotic cells and
in many viruses. DNA codes genetic
information for the transmission of
inherited traits.

Replication:
DNA replication is the biological process of producing two identical copies of DNA from the original/parentral DNA molecule.
This process occurs in all living organism.
Basis for biological inheritance
DNA Replication Is Semiconservative
Replication Begins at an Origin and Usually Proceeds Bidirectionally
DNA Synthesis Proceeds in a 5’-3’ Direction and Is semidiscontinuous
A reaction in which daughter DNAs are synthesized using the parental DNAs as the template.
Transferring the genetic information to the descendant generation with a high fidelity
Semi-conservative replication
Bidirectional replication
Semi-continuous replication
High fidelity
Replication starts from unwinding the dsDNA at a particular point (called origin), followed by the synthesis on each strand.
The parental dsDNA and two newly formed dsDNA form a Y-shape structure called replication fork.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

SIGNIFICANCE OF PROKARYOTIC DNA REPLICATION
Prokaryotic Replication
This process occurs in prokaryotic cells.
It is a continuous process.
Circular, double-stranded DNA
The DNA replicates in the cytoplasm
Single origin of replication
Small amount of DNA
DNA polymerase I and III are involved
Large okazaki fragments
The process is rapid, 2000 base pairs per second
Two circular chromosomes are obtained
DNA gyrase is required
