How is the integrity of the genome preserved?

  Defects in specific systems that regulate cell division are the root cause of genomic instability. It happens in a variety of cancer kinds. These flaws could be typos that don't get fixed when DNA is duplicated in a cell or mutations in specific genes involved in repairing damaged DNA. Cells respond to DNA damage by using a specific DNA repair mechanism that can be broadly divided into five categories: BER, NER, MMR, NHEJ, and HR. These pathways help cells retain genomic integrity. DNA glycosylases start BER by removing the damaged base to create an apurinic/apyrimidinic (AP) site. For an organism to survive and for qualities to be passed down to children, genomic integrity must be maintained. Genomic instability is brought on by DNA deterioration, abnormal DNA replication, or ad hoc cell division, all of which can result in chromosomal abnormalities and gene mutations. By analyzing the signal distribution across the size range and applying an automatically derived value,

What is the Difference between Vaccination and Immunization?

Image
  The terms ‘ vaccination ’ and ‘immunization’ are similar, but don’t exactly mean the same thing. Vaccination is the term used for getting a vaccine — that is, actually having the injection or taking an oral vaccine dose.   Immunization is the process of both getting the vaccine and becoming immune to the disease after vaccination. Giving a person a vaccination to protect them against disease is known as immunizing them. Immunity (protection) acquired through immunization is comparable to immunity acquired from exposure to disease, except that you receive a vaccine as opposed to the actual disease.   This is why vaccines are such effective medical treatments. The majority of vaccines are administered via needle (injection), although some are also administered orally or via nasal spray (nasally). Vaccinations, needles, shots, and jabs are other names for  immunizations . The term "vaccination" refers to receiving a vaccine, whether it be through an injection or an ora

What are the types of infectious diseases?

Image
  COVID-19 is a viral disease, just one of the four main types of infectious diseases. The others include bacterial, fungal, and parasitic—each different in how they spread and how they affect the body. Infectious diseases are illnesses brought on by pathogens—dangerous organisms—that enter your body from the outside. Infectious disease-causing pathogens include viruses, bacteria, fungus, parasites, and, in rare cases, prions. Infectious diseases can be contracted from other people, insect bites, contaminated food, drink, or soil. Worldwide, infectious diseases are very frequent, but some are more prevalent than others. For instance, 1 out of every 5 Americans contracts the flu virus each year, yet less than 300 people are found to have prion  illnesses . Here is a list of some of the most prevalent infectious diseases, organised by type. Common infectious diseases caused by  viruses : AIDS Hepatitis. Ebola Human papillomavirus (HPV). COVID-19.
