10 Shocking Results from DNA in Kannada language Kannada real fact DNA Replication ಡಿ ಎನ್ ಎ

Good morning Our earth has filled with wide variety of
creatures. We can find at least one living thing from
the deepest sea to tall mountains. Scientists have discovered nearly 13 lakhs of different
species which includes bacteria that was hidden from naked eye to blue whale, which weighs
some tonnes of weight and grass to eminent trees. An imagination is that this number may be
87 lakhs. But, what is the thing that leading us to
live and running us in a regular way? What is the reason behind unique appearance
of persons from one another in this world having hundreds of millions of people. What should be the height of a man? How should his looks be? how much delicious a mango should be how much proteins, vitamins should it consists
of and last what should be the color of a flower and what fragrance should it release etc, likewise the future of every living being
on the earth should be decided at one place i.e. In simple words, the root cause of living
and mystery of living is DNA only. What is DNA?
How it works? What will be the changes that happen in the future based on DNA Like these, Let us know about many interesting
things of DNA. You will be surprised if you know about a
great system running in our body in our absence of consciousness. So, watch this video completely. Every human life begins in same manner. Two single cells , each from mother and father
fuse together to form a single cell. Later, it will divides into two cells, again these two into four…. This division of cells continues upto making
of 10 trillion cells. How to form billions of cells into a human
shape, which cells have to make eyes, which cells have to make hands which cells have to make brain etc., can be
said by DNA, which means Deoxyribonucleic acid. It means
, all the instructions that tells how to build our body are present in the form of Genes
inside a DNA. To be simple, if DNA is a library then Genes
are the books present inside it. What color should we have, what should be our blood group, where to form
head, how many fingers should our hand have etc., information regarding our entire body is in
the form of Genes and reside in DNA. like this DNA contains nearly 20,000 to 40,000
Genes. In such a way, every living being contains
DNA having data related to their own body. Do you know? Genes in DNA of corn are more in number than
in the human. Ok, let us see how will be the DNA, pay attention. In the middle of every cell
of our body, DNA is situated in the form of double helix. It is made up of adenine, thymine, guanine
and cytosine molecules. These are simply represented as A,T,G and
C. In these, A always paired with T while G with
C. All of our genetic information is stored on
the basis of these configurations. In each cell, DNA is in the form of thread. Do you know? length of DNA extracted from
a single cell will be 2 meters length. Just imagine an invisible cell of size 0.09 micrometer
length, consists of 2 meter length DNA, what a wonderful construction it is! It means if we take out DNA from 10 trillion
cells of our body.. stretch it out from end to end, the length is enough to reach pluto from earth
and returns earth, Let us see how data will be stored in DNA. As we seen earlier, any of 3 molecules in A,T,G and C combine
to form a word. For example, ATC, TGA, GAC, CAG, etc. Here 3 letters are grouped to form a word, like this each cell of our body stores data
having length of 300 crore letters. all the human in this world constitutes 99.9%
of same DNA. remaining 0.1% causes difference in our color,
height, shape, lineament etc. Also, our DNA is 98% similar to chimps DNA. Another miracle is human DNA matches 50% to
a bananas DNA. Now we see what type of effect we receive
if a change in DNA occurs. As we have seen earlier that DNA is a sequence
i.e., made up of A,T,G and C molecules. Now, during cell division DNA in first cell
gets copied into second as it is. But, due to some occurrence of errors this
sequence gets changed and damages the DNA. Also, UV rays coming from sun or due to some chemicals or narcotics or during
smoking time, DNA gets damaged. Like these reasons DNA gets damaged nearly
10 lakh times a day. But our body has self repair mechanism. It replaces damaged DNA continuously. But sometimes damaged DNA cannot be repaired. This situation is called as “mutation”. Damaged DNA may not harm us or become useful
to us. but it can also leads to cancer. In 1990, American government wanted to find
the complete sequence of DNA so that they can find their genetic code. For this, they has started Human genome Project. It has taken 13 years to some hundreds of
scientists to find the sequence of 300 crore base pairs in DNA of single human cell. To complete this project, it takes 3 billion
dollars, which means more than 20,000 crore rupees
, as per rupee value no, Now, it takes one hour to read DNA of a person
at a cost of $1000 dollars, by this we can understand how fast this field
is developing. The information of our ancestors memories
and experiences is in our DNA. according to a recent study, we may receive effect from our ancestors of
14 generations. This is the reason why some people come up with analogy to their parents
or grandparents or uncles, or diseases that come inherently from ancestors
and only because of DNA. we have observed some people who acquire arts
by birth. Childhood onwards some persons can draw pictures, can do mathematical calculations well, this is due to one of the ancestors have such
capability and acquired through DNA. In this way, information regarding our ancestors is stored
in DNA. according to a study, we can store 215 petabytes
of data in one gram of DNA i.e., 21,50,00,000 ( 21 crore 50 lakhs) GBs
of data. Already scientists have started saving data
in DNA. first they convert digital data into binary
system then
it is encoded into 4 letter DNA codes of A,T,C and G. CDs, memory cards we are using today remain
for few years only. But data saved in DNA lasts for some hundred
thousands of years, safely. Now we are using large servers and huge data
storages for storing data. But the technology which stores data in DNA then we can store 10 crore HD movies in a
size of small eraser that resides at the top of a pencil. We can store entire information in this world
with in a shoe box sized DNA. In future there may be some days -when we
can store images, videos and other files in DNA. Now our scientific technology step forward i.e., Genome Editing, which means a technology which provides an
opportunity to edit and design our own DNA on our like. This is called as CRISPR. In
some families there may be some diseases which affect some generations inherently. In that situation, we can save our children
from such diseases.. by removing some part of DNA that is responsible
for disease. For example, assume father
is tall and has strength, mother is wise. Now, we can design DNA of born baby by giving
father’s strength and mother’s intelligence. Then newly born baby will has no defects,
such a days are ahead. Many persons die due to aging in this world. So to slow down old age and to improve human
life time, some experiments are carrying out. Do you
know? Jellyfishes dies only by killing, never by
aging. So, experiments are carrying to combine DNA
of Jellyfishes with that of human DNA. Elimination of death is impossible, so experiments
are conducted to improve life time of man. With this CRISPR technology scientists are trying to cure some terrific
disease like cancer, AIDS etc. scientists of kobe university in Japan, succeeded in blocking spreading of AIDS attacked
cells through Genome Editing. Main objective of this genetic engineering
is to cure diseases, getting babies without defects, increasing life span of man. But this DNA editing should be done very carefully. If any mistakes were happen while editing
genes then there is a possibility of unexpected
results. Finally, a
living organism- how to born, how to grow, how to behave etc should be decided by DNA. actually if we are a computer then DNA is
our software. A computer cannot run without a software and
the situation is same in us. Giving the ability to DNA to drive millions
of lives in a small cell that cannot be seen by naked eye, storing genetic information from many generations, all such complex structure is really a wonder. Ok friends, if you like this video then like. Share with
