How radiation affects DNA?

All of us are conscious of nuclear disaster and most people know how to it can be dangerous for us, it damages our DNA but how? let’s know.

What is radiation?

Radiation is energy in the form of waves or high-speed particles. It can be naturally occurring or artificially generated. Ionizing radiation, the most energetic type, can knock electrons out of the atoms in a process called ionization. This can damage DNA within your body cells.

Radiation can be considered in ionizing radiation and non-ionizing radiation. Ionizing radiations, which ionize atoms of our body cells and knock out electrons from atoms, which are x-rays and gamma rays and non-ionizing radiation are that which do not cause bad effects like ionizing one.

In the metric system, a radiation dose is measured in units called sievertsSmall doses such as those received from medical x-rays are measured in millisieverts (1/1,000) or microsieverts (1/1,000,000). Sometimes it is measured in rem ( 1 rem equals 10 millisieverts).

How it affects our DNAs?

When cells and what lies within them come to contact with the radiation, components of DNA get ionized by radiation, meaning that the electrons with atoms are kicked out from the chain and causes genetic changes in our body cells.

It does not affect our DNA as well the whole body.  Ionizing radiation leads to the production of free radicals and breaks critical chemical bonds. Generally, cells are damaged by free radicals all the time and repair themselves to keep the body healthy, therefore high doses of radiation can damage the cell’s ability to repair itself. Radiation kills rapidly dividing cells which is why we use it to treat fast-growing cancer cells. Some sensitive areas of our body which can be damaged or denatured by radiation exposer are the brain, eyes, thyroid (thyroid cancer), lungs, heart, gastrointestinal tract, reproductive organs, lymphatic system, and skin.

How the brain pays attention?

How the brain chooses what most deserves attention?

“There are a million things out there in the world bombarding our eyes, our ears, our skin, and other sensory organs. Of all those things, what particular piece of information do we most need to pay attention to at any instant to drive our behaviour.

Despite studying the forebrain of animals for decades, scientists have not found a good answer to the question of how the brain decides what to pay attention to.  The researcher decided instead to look at the midbrain, an evolutionarily older part of the brain found in everything from fish and mammals to birds and humans.

The researchers choose owls to study because they not only have sharp vision and hearing but also, like all birds, they have a midbrain organized in a way that makes it relatively easy to track the activity of specific neurons.

Here, while measuring the activity of individual neurons in owl’s midbrain, they found puzzling and unexpected. Although individual neurons usually encode visual space topography, meaning neighboring neurons encode the spaces for neighboring parts of the world, here they found single neurons responding to several pockets of locations, sometimes very far apart.

Success is a science; If you have the conditions, you get the results. Many students dream of being about a scientist, publishing their own research and being famous as Albert Einstein, actually it is not so easy researching anything without following a worthful process and having a better knowledge on the specific area. Don’t worry so much about this set back even if you have less knowledge.

So this article is written especially for you. Now let’s start your journey.

The art and science of asking questions is the source of all knowledge.

1. Picking out a topic which is worthful:

Selecting a topic ought to be done wisely because it changes the way to research every time. It leads your success so you should take a topic which is worthful, easy for you and problem-solving. Let’s consider an instance of AIDS/HIV which is incurable yet.

2. Study about the topic:

Now you should have a better concept The science of hive and aidson the topic on which you are going to research something. You should study on your topic deeply, here we have already taken an instance of AIDS/HIV. First, you should know the science of AIDS/HIV.

3. Study on the related topic:

It is necessary to know also about related topics, it gives us a better understanding of your research topic. Here HIV is a retrovirus (any of a group of RNA viruses which insert a DNA copy of their genome into the host cell in order to replicate) so it is necessary to know about different retroviruses in order to treat them better.

4. Study about every component related to the topic:

We already know structural details of the all retroviruses including HIV, further, we should know the structure and behavior of all its structural units to perform an exact experiment.

5. Study all the related researches:

This is the most important step of the whole process, knowing all related research on AIDS/HIV carried by others will give you extra marks in your research.

6. Trying experiments and collecting observations:

Now we are on the final step. Mind we are solving the incurable problem of AIDS/HIV. To destroy it we should need vaccines or drugs, we will try an experiment in every way. In this section, our creativity will be examined what we have in our brain. Mind it every observation should be collected carefully.

7. Be confident and publish your research:

Now we have done our experiments and found a desirable conclusion. You can publish your research in any research journal or can also apply for the patent to have the exclusive right.

In this article, I have tried to explain through an instance of AIDS/HIV but this belongs only not to biology but also to every field. You should implement it in your own ways for any kind of research. That’s all.
