¿Cómo hacemos nuevos genes? | Rafik Neme | TEDxBarranquilla


well I want to start today I bring you

a memory of my childhood when I was

boy for school I had to make a

plasticine cell played arm a

cell here I or laziness that coexist

the parts of that cell in which I

He said how it looked I know that all

we here should have done some

exercise class as the sheep be a

exercise as is done by the brothers

children or we could do our

students and I think you remember the

tomorrow people were left with an idea

I made a cell in a villa but for me

that started a journey that took me in the

time and space to become a

single night a little too the school is

everything that is alive is made of

health for example a bacterium is

made from a single cell and we

We are made of millions and millions of

cells that we humans are

cells like genes and animals both

plant cell is to make them slightly

life is made health and what is more

important that they organize them in a

particular way but we can go a

little bit beyond and look at what happens

single cell and a little beyond

look what happens inside is to make it how

the different courtyards are organized

Portuguese cell bodies beyond

look inside

the nucleus of the cell where it is organized

all the information that he tells the

cell to be this the genome that a

long long chain and the genome is a

collection of genes or even more inside

in I think for the moment and

we think we’ve started was a

person and we walk inward

go in and now we are in

the most intimate part of life that is

urgent everything stopped if we look towards

outside

the cell is organized from that

information bit

I come to talk a little about what

we do like us

we imagine in science that they stop

function

they make the genes but for that first

that what the genome imagine as

a long long line telling him that

in the regions the pieces that go from

one side to the other that we call

genes are regions of the genome that when

the city needs something for copies

of just that little piece and for example and

those those copies serve the cell

as an instruction so that they have

instructions that will run a routine

and from the eye for example there are some cells

that have an instruction that detects

where there is light and where there is no light and

example in the language

there is an instruction that says this is

bitter sweet and things that are very much

more elaborate much more complex as

our ability to think our

ability to dream to imagine

things also have a basis in genes

there are genes that organizes information from

so that we can now think no

we know how all the genes work

but we know that it has a foundation

it turns out that the cell is not an organism

present perfect that as well as I know

Now described that happen

this the only real thing is that the agency

he also makes mistakes and from time to time

when it produces a bit of instructions

in other parts where images or you have to

make everything produced by mistake and

many of those genes are many of those

bits do not do anything nothing happens if

what makes them produce is like no

they would shout something in the street that no

understood and continues straight when a

bit that causes a real instruction

the routine between the cell and for example

in some kind of cell we are going to do

that the organism has been faster and has been

faster and that’s important for

example to escape a predator was

important for example to pursue

a prey to get food for

pair

that is beneficial for the organism and

we want to retain it and the cell

has eventually developed a way

how to mark those bits and turn it

genes then of a serious error

produce an instruction to the toya by

unity

looking at how blindly it came about in is

an idea that we believed that

we think that it works more or less in

the nature and how new ones are produced

things and this we validate what we look for in

other time scales but it was said

that this takes me back in time and it’s because

example if I want to understand neither what

human and again the line with pieces

of genes

I want to understand where the

genes what I do is everything very

simple and that is that I compare with other

very human species

kiko mouse pay a fish and as I do not

we only have an idea of ​​the relationships

evolutionary among those species

we know that the human is closer to the

mico and that then in 32 the mouse is the

which is closer to those that are left

we can not go organizing in groups that

the group does not represent time in the

past

the common ancestor between the human and the

mico more recent than the common ancestor

between the human and a weight and if we eat

the genomes of those organisms and

we look for the genes that are expressed

genes that must align with those we

we realize that for example in the

fish and in it the bird there is not that gene

ps does not exist is what he tells us

US

it happens is that approximately 100

millions of years when they still existed

dinosaurs on earth

that did not exist but then time for

here the lineage that gave birth to

mice to humans to the nation micos

people left that we draw half

It will be known soon although

we can give age to the great

topics new genes older ones you see

you on the sides because they are very old

because they are present in all

species as a viewpoint but it results in

We also have to try

our idea when we say albi and we have

observed the patterns and it occurs to us

something have creativity

we have to try the note to prove

that there are genes that are born humans

very difficult for a simple idea and it is

that we take a long time to

reproduce them in time they take for

example 20 25 years a new generation

human and if I want to try is one day

I do not have all my life

to expect all the feeling is that in

this to see it

then the trick that occurs to us

we were bacteria that in a

Week bacteria tests

generations of bacteria

I for collecting 200 years 200 years of

human life and it is imagined that I

I start an experiment when Colombia

is becoming independent and the new

mirador result of the experiment today

that’s the same thing I can do with the

bacterium already starts the experiment Monday

and it ended on Friday and I can look at what

happened in a week with cousin the scale

of evolution time and could observe

the evolution of new genes in the

laboratory or that ‘s what I wanted

do with this

the trick is simple a matter like what

what I want to try are those little pieces

of instructions that are around the

genome that are not genes or a lot of

bits that does not make any sense

but even so they do not say anything but they are

pieces of DNA from the bacteria methods

and then I have many bacteria with those

bits and each bacterium has something

different if it would be an urn have

some things at first glance it might seem

very interesting and other things still weighs

the trick here discern which of those

bits gives a bacteria an advantage

on the subject all that I like the

bacteria, we put clothes on

experiments in which we put the

bacteria growing and we wait then

we can continue

we lived in a week we were

we were a few weeks and that whoever

feel and it turns out that there is bit to

instructions to which we put

to the bacteria that we do not know

that are initially that we now know

that has an effect and there are some that in the

as we put the

experiment those bacteria disappears

that remember what they had about

you did not see her again

we can say that there is one of

those instructions that are good

positive for the bacteria and others that

they are negative and we are

looking to try with people something but to

margin any find

definitely we can collect

that idea that I told them about how

city ​​is organized and like all those

genes from no instruction

that is not good for anything good to do in

a week we compress that and it’s the idea

that I had with looking at other patterns and

do the ipom experiment we find

this but also that if we take those

pieces for example that can produce

the gift and hat and I want now

the piece that the hat produces

wants to use for different purposes and

is for example there are bacteria and

cellular organisms that we

they hurt

hundreds there are bacteria for when

we need antibiotics but as

been consuming lukewarm therefore

existence time and we

we need to kill the bacteria support

to kill us and there are also

other cells in our body that do not

they produce cancer and that kills us

if we are able to take those

fragments that we do not know that always

they hurt a cell and we put them

inside those cells

what happens if then we are able now

with this type of system to develop

molecules to develop instructions

that if we put in the cells

they are going to kill the cells that we do not

we want to have something that seems to be

negative because life is very positive

for us as an imh tool for

me this is very rewarding in the

I sense that I like to do science

such that I like to understand things

but also important that one does

science that he has a service for the

people and I think this has all the

potential to be a tool for

that we do not over put many

of the challenges that we are going to have as

species and I want to take them back to

that is the memory that after them that

I remember but I hope that also

within each of you something of

that memory has to have and it’s like

we can combine creativity

of one as a child to be interested in something

how can we combine the creativity of

a scientist the creativity of the

cell because the cell is also

solving your problems with those

innovation production mechanisms

of production new things takes

solving your problems challenges and thousands

of millions of years and know how

integrate all that I want to be

take that and it’s that memory of your

cell is much more and can be

now the solution to a problem

great humanity but that is

He filled the house with many thanks
