Bacteriophages: Our friendly neighbourhood





Bacteriophages are the virus. These are non-cellular organisms. Thus they are not considered as living. They seem to be mechanical as someone made them. They are motile. Consists of a crystalline head, collar, sheath and tail fibres. They contain RNA as genetic material.   

They found everywhere from eyes to eyelids. They found much more than any organism. They are the deadliest being on the planet. They daily kill 40% of bacteria in the oceans. They are much smaller than our cells and bacterias. They are known as bacteriophages because of they phages bacteria. Each bacteriophage terminates specific bacteria.

When bacteriophage finds it's victim, then it injects its genetic material inside the bacteria. This produces many new phages inside the bacteria body, which releases an enzyme called endolysin. This enzyme punches the hole and causes bacteria to burst. With the burst, those bacteriophages come out in the environment. Fortunately, bacteriophages can't harm us even when our cell and it encounters each other because bacteriophage ignores our cells as the human cell is not it's a specific victim.


Till 200 years ago a single cut sometimes kills a person due to bacterial infections and luckily we found an antibiotic from algae called Penicillin. But due to more use of antibiotics bacteria get evolved and immune to it and antibiotics also kills the good bacteria of our body. 




When bacterias get evolved it becomes a superbug but, bacteriophages can destroy them. With the evolution of bacteria, bacteriophages also evolve. Bacteria who get immune against them, lose its resistance to antibiotics.


 A few years ago an old man gets infected poorly by bacteria named as Pseudomonas Aeruginosa in his chest cavity. This bacteria is naturally resisted to many antibiotics and can even survive in alcohol. In the end, doctors experimentally inject bacteriophage into his chest cavity and within a week the patient gets cured completely.


The bacteriophages are our friendly neighbourhood.

CLASSIFICATION OF PERSONALITY ON THE BASIS OF BODY TYPE (Physique) by W.H. Sheldon

W.H. Sheldon William Herbert Sheldon was a American psychologist who  classified personality of an individual on the basis of body posture and shape  which are endomorph, mesomorph and ectomorph. Endomorphs Endomorphs have short arms and legs. that is their limbs are shorter due deposition of adipose tissue. It is hard for them to loose weight. They have soft body and have high capacity for high fat storage. Their excessive mass hinders their ability to compete in sports, but those sports which requires strength like weight lifting, powerlifting and wrestling are suitable for them. Mesomorphs Mesomorphs have athletic physique and body composition, their chest and shoulder are broader than their waistline.  They can easily gain or loose weight. they can perform well in sports need strength, agility and speed. Ectomorphs Ectomorphs are slim. they have elongated muscled and limbs, They usually face great difficulties in gaining weight. Their chest is also flat and have less ...

Alien Disclosure: Part 2

 American airforce declared that the leaked videos of UFOs are real and was recorded by American airforce. We still don't know about area 51, 52, 53 and many more. UFOs had been seen there and nearby region many times. Maybe the American government is hiding something extraterrestrial such as the alien spaceship. American government marked these areas restricted by the military. Is intelligence agencies of many nations know about the nonplanetary organisms? If yes, so why they don't disclose about them?  What you di, if you come to know your neighbours are actually aliens? This will be really shocking. Maybe they have a base on earth. It is possible that they are present on our planet much before our existence.  In human history, there are many things that were impossible for humans to do at that time. Such as Stonehenge and Pyramids of Giza. Even a group of people can't lift those heavy stones whose weighs in tons.  So, what do you think...

DNA FINGERPRINTING

  What is DNA fingerprinting?   Alec Jeffreys DNA fingerprinting is a technique to identify a person based on his/her DNA specificity. Every individual organism is unique. Thus every person has unique DNA fingerprint. It can't change by any known technique. It is a quick way to compare the DNA sequences of any two individuals. DNA fingerprinting developed by Alec Jeffreys.     Paternity test Applications:   Paternity test Criminal Identification Determination of population diversity Determination of genetic diversity   Principle: It has found that the DNA of an individual carries some specific nucleotide sequences which don't code for any information or proteins. These sequences repeated many times and found at many places throughout the DNA. These sequences of satellite DNA which are very specific in each individual and vary in number from person to person and are inherited. These are a variable number of tandem repeats (VNTRs). Each individual inherits th...
