Amazing and Interesting facts about your Brain and DNA.

Brain and DNA facts

Wondering about how your Brain and DNA works? Don't worry today I am going to explain about Brain and DNA, and how it works.

According to scientists Brain and our Body DNA are the most complex things in our Human body, Below are some facts about our own Brain and DNA.

The modern brain is an energy hog. The organ accounts for about 2 percent of body weight, but it uses about 20 percent of the oxygen in our blood and 25 percent of the glucose (sugars) circulating in our bloodstream.
The foundation for the brain is set early. Three weeks after conception, a sheet of embryonic cells called the neural plate folds and fuses into the neural tube. This tissue will become the central nervous system.
Velocity of signal transmitted through a neuron = 1.2 to 250 miles/hour, Wow! that's more then the speed of a super Racing car.
There are as many neurons in the human brain as stars in the Milky Way. So it is better to count the stars in our galaxy rather than going for the neurons in our brain.
The largest part of the human brain is called the cerebrum. Other important parts include corpus callosum, cerebral cortex, thalamus, cerebellum, hypothalamus, hippocampus and brain stem.
A thought is a physical pathway in the brain. The more you have that thought the more you groove that path and the easier it is to have it again. That's why having the thought "Why do I suck?" is never a great idea.
Your brain has no pain receptors which is why if I managed to remove the top of your skull without you noticing I could poke around all day without you feeling a thing. The skull removal may hurt a bit though.
Until relatively recently scientists thought that the brain was the only area of the human body that didn't generate new cells. We now know that's not true and the brain does reproduce shiny new cells for you to use.
Your brain is constantly lying to you when you have your eyes open. Because it cannot deal with every single detail that you're looking at, the occipital lobe is joining the dots with what it presumes is there.
Similarly, your brain doesn't record memories like video as it would be easy to assume. It takes snapshots of the more important bits and then when you recall the event it guesses what happened in between based on prior experience.
This was some amazing facts about our Brain, Now lets move to DNA.

# DNA is like a computer program, Everything is programmed in DNA and it controls and give instructions to our cell to do responsible tasks. DNA contains some special types of letters(program)that your cell can understand.

99.9% of our DNA sequence is same as other humans, Then you may be wondering that there is only little difference between einstien and you. But the remaining 0.1% makes a lot of difference between you and rest of the people.
Our entire DNA sequence would fill 200 1,000-page New York City telephone directories.
If unwound and tied together, the strands of DNA in one cell would stretch almost six feet but would be only 50 trillionths of an inch wide.
If all the DNA in your body was put end to end, it would reach to the sun and back over 600 times (100 trillion times six feet divided by 92 million miles).
The CODIS databank (COmbined DNA Index System) is maintained by the BI and has DNA profiles of convicted criminals.
Lengths of connected DNA molecules, called genes, are like tiny pieces of a secret code. They determine what each organism is like in great detail. Almost all the DNA and genes come packaged in rod-like structures called chromosomes--humans have 46. There are 22 almost identical pairs, plus the X and Y chromosomes, which determine if a human is male (one X chromosome and one Y chromosome) or female (two X chromosomes).
The DNA information in a single sperm contains 37.5 MB worth of data? Which means that an average ejaculation almost instantly transfers roughly 1.5 1,500 terabytes of data. Suddenly USB 3.0 doesn't look that impressive when compared to what Mother Nature's been using for years.
An animal's entire code, comprising a long string of the letters A,G,C,T, is called a genome. The human genome is about three billion letters long. Just think if that was written in the normal letter size like the letters you are reading now, then it covers kilometers of distance.
Most of our genome is made of junk DNA. This junk is compressed either of deactivated genes that were once useful for our non-human ancestors(like a tail), or parasitic DNA from virus that have entered our genome and replicated themselves hundreds or thousands of times over the generations, but serve no purpose. Genome size is therefore not related to the complexity of life. For example, the genome of the unicellular amoeba has been reported to contain more than 200 times the amount of DNA in humans.

Interesting stuffs about human body.

It takes food seven seconds to go from the mouth to the stomach via the esophagus.

The average human dream lasts only 2 to 3 seconds.

The average American over fifty will have spent 5 years waiting in lines

A sneeze travels at over 100 miles per hour. Gesundheit!

Your thigh bone is stronger than concrete.

Your fingernails grow almost four times as fast as your toenails.

You blink your eyes over 10,000,000 a year.

There were about 300 bones in your body when you were born, but by the time you reach adulthood you only have 206.

Your brain is move active and thinks more at night than during the day
Your brain is 80% water

Your pet isn't the only one in the house with a shedding problem. Humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70.

Mind blowing facts about our human body.

1. DNA tests can help you understand your family history aka genetic genealogy.
2. If all the DNA in your body was put end to end, it would reach to the sun and back over 600 times (100 trillion times six feet divided by 92 million miles)

Nerve impulse to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It's due to the super speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.

The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn't too far off the mark. Your brain generates as much energy as a small light bulb even when you are sleeping.

A kitchen faucet would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime

 Women are more likely to gain weight than men during the first few years of marriage.

Germs only cause disease, right? But a common bacterium, E. Coli, found in the intestine helps us digest green vegetables and beans (also making gases – pew!). These same bacteria also make vitamin K, which causes blood to clot. If we didn’t have these germs we would bleed to death whenever we got a small cut!

When you wake up in the morning you are at taller than when you go to sleep, because you have let your spine straighten back out after all the bending, sitting, and moving you have done!

The farthest you can see with the naked eye is 2.4 million light years away! (140,000,000,000,000,000,000 miles.) That’s the distance to the giant Andromeda Galaxy. You can see it easily as a dim, large gray “cloud” almost directly overhead in a clear night sky.
