ther are different types of pathogens like bacteria and viruses which cause disease by self replicating.if we talk about bacteria it divide into two with in specific time i.e e.coli divide into 2 after every 20 minutes by replication.it divide its genome into 2 and synthesize new strands according to the semi conservative model.

What are the three specific steps for destroying pathogens?
Disrupting the pathogen's cell membrane or wall using physical or chemical means. Inhibiting the pathogen's metabolic processes or replication through heat, radiation, or disinfectants. Blocking the pathogen's ability to infect host cells or evade the immune system through antibodies or antiviral drugs.
What is the importance of DNA replication in the cell reproduction?
DNA replication is significant in the reproduction of cells through the mechanisms of mitosis and meiosis. The DNA replicates so that there will be an extra DNA when the cell multiplies, allowing the "daughters" the chance to reproduce.

What is subtractive genomics?
Subtractive genomic strategy is developed by assuming that the novel targets identified in the pathogen should be essential for the pathogen that is it should be involved in the replication, survival and a important component of various metabolic pathways and mechanisms occurring in the pathogen while at the same time should be absent on the host that is human and should have no homologue in human, so that when a drug or a lead compound is designed considering the potential target it should only be against the mechanism and functionality of the pathogen not the host.
How is the number of replication errors in cells kept to a minimum?
Cells have various mechanisms to ensure accurate replication and minimize errors. These include proofreading by DNA polymerase, DNA repair pathways, and cell cycle checkpoints that monitor DNA integrity. Additionally, telomeres at the ends of chromosomes help prevent loss of genetic information during replication.
What kills cells infected with a pathogen?
Cells infected with a pathogen can be killed by the immune system through mechanisms such as releasing toxic chemicals, inducing programmed cell death (apoptosis), or activating immune cells like T cells and natural killer cells to target and destroy the infected cells.
Describe two mechanisms that operate to restore homeostasis after infection by a pathogen?
Gaben at valve
What is colonisaion in infection?
As you probably know, colonization and infection are 2 separate events.Colonization occurs when a pathogen enters a wound then replicates.Once you have colonization/replication of a pathogen in a wound, the wound will (most likely) become infected.
An animal insect or human whose body is capable of sustaining the growth of a pathogen is known as what?
An animal, insect, or human whose body can sustain the growth of a pathogen is known as the pathogen's host.
What are the differences in the functions and mechanisms of action between helicase and topoisomerase in DNA replication and repair processes?
Helicase unwinds the double-stranded DNA during replication by breaking hydrogen bonds between base pairs, while topoisomerase helps relieve the tension and supercoiling that occurs ahead of the replication fork by cutting and rejoining the DNA strands. Both enzymes play crucial roles in DNA replication and repair processes, but they have distinct functions and mechanisms of action.
How is bacterial DNA replication different from eukaryotic DNA replication in terms of process and mechanisms?
Bacterial DNA replication is simpler and faster than eukaryotic DNA replication. Bacteria have a single circular chromosome, while eukaryotes have multiple linear chromosomes. Bacterial replication occurs bidirectionally from a single origin, while eukaryotic replication starts at multiple origins. Bacteria use a DNA polymerase III enzyme for replication, while eukaryotes use multiple DNA polymerases.
What are the key differences in the genetic material replication process that DNA uses, while RNA uses a different mechanism?
DNA replication involves the synthesis of a new DNA strand using the existing DNA as a template, while RNA replication involves the synthesis of RNA using DNA as a template. DNA replication is highly accurate due to proofreading mechanisms, while RNA replication is less accurate. Additionally, DNA replication occurs in the nucleus, while RNA replication can occur in the nucleus or cytoplasm.

How accurate is the process of DNA replication in ensuring the faithful copying of genetic information?
The process of DNA replication is highly accurate in ensuring the faithful copying of genetic information. The enzymes involved in DNA replication have proofreading mechanisms that help to correct any errors that may occur during the process, resulting in a very low error rate.
The faithful replication of DNA prior to cell division depends primarily upon?
The faithful replication of DNA prior to cell division depends primarily upon the enzyme DNA polymerase, which reads the existing DNA template and synthesizes a new complementary strand. This process ensures that each daughter cell receives an accurate and complete copy of the genetic information. Additional proteins and mechanisms, such as proofreading and error correction mechanisms, also play a role in maintaining the fidelity of DNA replication.
How does the glandular fever pathogen divide inside the body?
The glandular fever pathogen, Epstein-Barr virus (EBV), infects B-cells in the body and replicates within these host cells. It utilizes the host cell's machinery to multiply and spread to other cells. This replication process contributes to the symptoms associated with glandular fever.
