DNA replication

DNA is the career of genetic information. It carries properties of living organism from ancestor to offspring. 

DNA is a double hellix structure where two single hellix RNA coiled and form a spiral structure. 

During cell division DNA have to devide into single hellix RNA. Two RNA seperated and each RNA forms its copy to form a new Two DNA.

Coiling of Two single hellix RNA to form New DNA is called DNA replication.

Microorganisms

Microorganisms in microbiology indicates the living organ unicellular,  or multi cellular, even particles like virus.

The members of microorganism includes, 

Bacteria : examples,  clostridium titani

Virus: HPV,  Tobacco Mosaic Virus

Fungus: Candida Albicans that causes oral candidiasis

Protozoa

Antibody

Antibody is a protein in animals body to fight against specific types of antigen. Antigen is foreign living pathogen that usually harms body.  

Antibody made inside the body kills foreign particles. Foreign particles should be bacteria, virus or fungus.

Antibody is the active part of our immune system. It is also indicator of immunity. Who gained antibody against specific disease he gained immunity against specific disease.

Bacteria

 Bacteria is a living microorganism that is unicellular and consist with nucleus protoplasm surrounded it. 

The basic difference of bacteria and virus is that it is independently alive. But virus is alive when it hosted by living organism. Otherwise it is particle.

According to gram staining experiment bacteria is gram positive and gram negative. 

According to survival capabilities in presence of Oxygen bacteria classified into aerobic bacteria and anaerobic bacteria. 

According to infection capabilities bacteria are classified into pathogenic bacteria and non pathogenic bacteria.

Centrifugal force

Centrifugal force Centrifugal force is a ficttious force in Newtonian classical mechanics. In every rotating frame of reference. In rotating device like centrifugal pump, centrifuge, centrifugal clutches, centrifugal force is applied. Earth is a rotating frame of reference but it's fictitious force is small due to slow rotation. In any point of earth surface the strength and local gravity is the combination of centrifugal force and gravitational force. An object weighted on a spring have two force. In downward direction we find gravitational force and in upward direction we find restoring force of spring. Rotating force motion results another fictitious force that is called Coriolis force. Rate of rotation in a frame of reference if changes another fictitious force is required that is called Eular force.

Centripetal force

Within nucleus electron revolves surrounding nucleus is not collapse even, not go far from nucleus. It is nothing but a result of electrostatic force. electrostatic force is a combination of two forces opposite direction. These are centripetal force electron direction toward centre and centrifugal force which is directed opposite of centre. According to Rutherford atomic model, both forces are equal and opposite direction within an electron. Centripetal force Directed toward the centre of atom. Any forces directed toward centre is centripetal force. Centripetal force are always found in circularmotion. When any object moves circularly the centripetal force act towards centre of the circular path along with radius of the circle. The force is always orthogonal and fixed to the centre of the curvature. Gravity is a best example of centripetal force. Issac Newton says that it always drawn object. In Newtonian classical mechanics, Centripetal force causes due to orbits of astronomical objects.

Gene transcription

Gene transcription is a process of producing RNA from DNA. DNA polymerase enzyme used to breakdown of DNA into two single helix RNA. Special types of DNA binding protein is required That is called transcription factor.

Genetic linkage

Genetic linkage is a term that indicates the tendency of inheritance of two nearest gene sequence in a chromosome during meiosis cell division. Gene linkage is the most important expectation in The law of independent assortment by Gregor Johannes Mandel. Two genetic marker in a chromosome inheritance probability depends on distance between themselves. this distance is count by centi Morgan. The nearest gene sequence have highest chance of inheritance and less chance of Genetic recombination . During Genetic crossover two physically nearest gene in chromosome is unlikely to seperates into different chromatid during meiosis Cell division .

When any Cell divides there have a chance of separate the chromosome into different chromatid.

In different types of plant examples of genetic linkage may be found. We may find that rates of seed dormancy even germination somehow linked with genetics and genetic linkage.

 

Grapes

Grapes

Grapes are abundant of Vitamin C, antioxidant, menerals like calcium, magnessium, potassium. These abundance of nitrients provides a lot of health benifits.

It boost immunue system

Because of having Vitamin C in grapes it boost immunity. Vitamin C fight against virus and bacteria as well as yeast infection. 

Poassium in grapes improves heart health. Water prevents dehydration. Calcium improves bone hearlth. 

Antioxidant in grapes reduce the risk of cancer by reducing free radicals.

Gene expression

Gene expression is a process of encoding Gene into DNA to form final product protein.

There have two process of gene expression One is Gene transcription and another is translation.

Through, a gene expression process genotypes appears as phenotypes. 

There, also have some steps of gene expression. These are,

Transcription 

RNA splicing

Translation

Post translational modification

Gene regulation

Banana and its health benifit

Banana is a very nutritious fruit that contains essential elements for our healrh.

It supplies a lot of vitamin and minerals to body. Banana is a rich vitamin C abundant fruits. 

Banana comes from plant family called Musa. Mostly it grows in south Asia. It contains fibres, minerals and vitamins. The potassiam in Banana is beneficial for normal heart rate. It controls blood pressure effecgively.

Vitamin B6, and antioxidant improves health condition.

Banana is a fruit that can consume when it unriped as well as when it riped. In unriped banana carbs is presents as 80 parcent of starch. But when it riped it converts into sucrose, glucose and sugar.

The starch of Banana in our large intestine forms butyrate by bacteria fermantation that is a short chain fatty acid. It improves our gut health.

Banana contains dopamine. But the dopamin of banana does not cross blood brain barier. It acts like an antioxidant.

Catechin: Banana contains several types of flavonoids. One of the most important flavonoid is catechin. It reduces the risk of heart disease.

Resistant starch and pactin is a diatery fibre and both of the element asc as prebiotic nutrient to grow bacteria in gut. Hence it provides gut health benefit.

How to Germinate seed effectively？

Seed is a zygote that is able to produce new plant if favorable environment is available.

Atomic size

The size of an atom depends of different things. Read mor

Attractive force

The force acting among the objects that tends to closer together is attractive force. The opposite concept of attractive force is repulsive force. Repulsive force tends the particle to go away as far as possible. within an electrostatic force there exist both attractive force and repulsive force. centripetal force tends to electron to go to nucleus and centrifugal force tends electron far away from the nucleus. Within a magnet we find that opposite pole of magnet attract each other and same pole of magnet repulse each other. Same electric charge repulse each other and opposite electric charge attract each other.

Do you think about your child that your child is intellegent enough？

 Do you thinking about your childs intellegence. Intellegences is a capability of solving problem. 

Each and every living organism have some specific skill and knowledge of problem solving. Specially, problem concerned with surviving have naturally acquired knowledges. 

Brain and body have a significant relationship. How much any animal will be intellegent depends on its body weight and brain weight.

Standard model

Governed by fundamental force, how matters building blocks interacts is explained by standard model in particle physics. Everything in universe found to made by some building blocks called fundamental particles. These fundamental particles how interacts governed by fundamental interaction is explained by Standard model which is developed in 1970.

Eucalyptus and its Health benefit

Eucalyptus is a forest plant well known to grow within shortest time. It have a lot of health benefit besides of economical benefit. Eucalyptus oil provides significant mechanism of treatment of pain and inflamation.
