Hmm... not sure if this is a serious question or not... sounds
answerable though so I'll give the benefit of the doubt (:

Nope, if you have a large enough amount of DNA that you can see it, the
DNA is transparent! It has no colour.

The green and brown colour of algae is probably due mostly to
chlorophyll, which is a pigment that absorbs sunlight for the conversion
of sunlight to energy. They use it to 'power' their cells so the can
move, reproduce etc. They're some of the original 'solar cells' (:

but algae has dna right - what is dna's role in algae's life... is it just
an enscription

ok i am serious but sometimes i ask stupid questions...

i still dont want to give up...
why i see dna in colour of algae's greenbrown i dont know i wanted to
connect the dna with thoughts of human beings and i know there is some
connection ...

the reason for this is how people behave when you ask them "if the
army-military was canceled or shutdown in the political system" as a reward
to our futures kids - would get sick and have twisted answer like they cant
answer by themselves but the answer would become so general like the society
is answering not the individual and thats why i connected the colours of
the military with algae colours and DNA is something inbetween - that makes
the human a marionette or...

Same as in yours; it is the genetic information (the blueprint).


I would modify Scott's answer slightly by saying that DNA is white, if
you actually had pure DNA (a white solid). Solutions of DNA are
transparent -- at least for visible light.




nope; only that the DNA of humans is responsible for us developing a
brain.

Every living being on this planet (all bacteria, algae, plants, insects,
animals, people...) are formed through the DNA that they received from their
parents. That is the genetic code - your parents made you by combining their
DNA into an egg. Bacteria and algae get their DNA by the parent splitting
into 2 offspring cells.

The DNA directs the whole process and forms a being according to the
information in the DNA. An offspring can only be the same as the parents
because that is the information in the parent's DNA.

An algae's chlorophyll is an inherited trait because the parent's DNA coded
for it. Algae have chlorophyll, humans don't.

Yeah, but it's not really white. It's only white because of diffraction
and reflection, not colour... Same as salt and sugar. They're actually
colourless, not white.


No problems with asking any questions you want! The only reason I posted
that bit at the top about whether it was a serious question is that, on
this group, it's sometimes hard to tell... there's always people posting
strange things and often they're obviously not serious... so ask all you
want!


Yeah, the colour you see is not associated with the DNA of the algae,
anymore than it is associated with the gree colour of plant leaves, the
red colour of an apple or anything else. An overly simplified
explanation is that the DNA is just a long set of instructions for how a
cell should construct it's components.

Hope that makes some sense.

Cheers,

Scott.

Our DNA "works" on our colour (eyes skin whatever) it does not have a
coulour itself neccessarily... for example my grandma has grey eyes and my
granpa had brown but my moms eyes are brown does that mean my grandmas' DNA
was to lazy to work its way to victory ...

So humans are just like complex books walking around the world, working,
talking, loving and there are more liitle books, animals and plants around
us that we see, love ,pet or look after...

I am interested in this is there any way DNA works on how a human thinks -
for example my parents gave me 50% of their genes each and sometimes i have
something that is smarter than what they had or of what they gave me - my
DNA has learned a new way to work better or something like that... Does that
mean i am 50% more advanced ...


Can a human "write" new stuff to his DNA - just for fun... if you know
something transparent is working for you - you'd be the administrator of
your own DNA...

the real reason of my interest in DNA is this - i also dont expect positive
answers cause this has something to do with an idea coming from the future
(the nice part of the future - if people like this idea we can all live in
peace then) - croatia has implemented a system - for people who are citizens
of this country - who do not wish to carry guns or learn how to use them
because their consciousness tells them to do so - they are a part of the
civil service system and they have to serve some government or state
institution for eight months if they do not wish to serve the regular army
where 18 year olds have no objection in carrying guns or learning how to
kill another human not actually but the whole army thing has brought nothing
good to humanity - 90 % is going in the regular army and 10% is a social
worker - these 10% are saving the life of the children of the future so the
number is increasing - people still care about good things and life because
we wouldnt be able to survive if we had no entertainment coming from good
things or a good source - i worked as a social worker for 8 months in the
government office and figured what time and parts of my thought process i
would have lose if i went to the regular army - i would lose a lot but i
would never jeopardize my morale codes i always hated the army since i was a
kid and later i got beaten because of this and humiliated often and saved by
good people- but i also am one of the strongest people on the planet just
because - many people think i will never persuade someone to cancel the
army - its a bloody job. The army in the US or its branches has technology
that the civil populi has ever seen and its worth enough to feed the entire
planet for 30 years and enough to fund laboratories for doctors and
scientists to find out cures to deadly diseases...

einstein hated the army especially when solidiers would march - there is a
french saying with the devil we marche - thats sick - well mad people work
in the army anyway... i hate it anyhow ... but thats why i am interested in
how to fix things DNA works in tachyon speed and one good argument can
persuade people to believe in a better life... this is a bloody job and its
hard i know but i need some info on the possibilities how to make DNA work
to work for noble stuff - nobility is what lacks in the world society - so i
would expect some noble ideas from people who read this - every genius loves
to talk to his or her DNA ...

....at least tell me this would you (scientist or whoever) have more funding
if the military was proclaimed an obsolete organ in our society...

Google Mendelian genetics



It would be very hard to find out how someone thinks by looking at their
DNA. I'm sure most behavior is associated with DNA, but that idea is
still very controversial as well as very hard to test. Check out
sociobiology or evolutionary psychology.

Well not right now. maybe in the future if molecular biology and
genetics ever lives up to the hype. As you may know we can genetically
modify certain organisms by inserting genes into very young cells. The
problem is that an entire human is trillions of cells and each cell has
all of the same DNA wrapped in 46 chromosomes. The idea is to get the
gene you want to insert into the organism into enough cells to produce
enough of the desired effect without any negative results. There are
some techniques that are using viruses to insert genes in humans, but
the technology is still being tweaked.


So I'm assuming you want to learn about DNA to be able to change
people's DNA and thus change their behavior to that of a non-killing
person. That might be a noble cause, but do you intend to do this
against someone's will. Science is governed by ethics, and that is
unethical.

At least you have a curious mind and I suggest getting a student visa to
the U.S., Canada, U.K., Germany, or someplace where your degree is
recognized everywhere.
I've got bad news for you. Most scientific research is funded by the
military (at least here in the United States). The military has a lot
of interest on new technologies that may come out of basic research that
can be used for military purposes. I'm sure the questions you are
asking about DNA right now what to be found by the military for use as a
weapon. I find this unethical because I do believe science can take
this planet to the next industrial revolution. The only question is,
will science share these advancements with all, or will it be sold to
the highest bidder and used for the consolidation of power?
