It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

From Tree To Web
A Quixotic Quest
“The tree of life is a record of how every species that
ever lived is related to all others back to the origin of life.”
For a period of 150 years
biology sought the holy grail
of the tree of life – today
the tree has become obsolete
through negative evidence
Discovery of DNA structure led to
molecular evolution studying inheritance
as contained in the history of DNA sequences
finding species swapped genetic material
with each other, hybridising - thus the tree-
theory degenerates into impenetrable
thickets of interrelatedness
Bacteria and archaea swap
genetic material with other species
across huge taxonomic distances
in horizontal gene transfer (HGT)
Darwin assumed 'vertical' descent
but when genes were sequenced -
DNA replication and protein synthesis
showed the promiscuous exchange
of genetic information across
diverse groups

This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.

It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.

It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule.

Into God Worship
You shall not pernit a false teacher to seduce you or,
Pull you away into God Worship! !
And stay away from the genetic engineering which involves the mixing of two species,
For, they are all part of Satan's work to elude many into her fold.
Par, stat, tar, car, far, bar, gar, jar, oar, war!
Spies,
Species,
Alone once again! !
And, back to square one;
But, stay away from the genetic engineering which involves the mixing of two species!
And, live like the muse of love in the land of your joy.

Genetic studies in Iceland have found that many of the women who were the founding stock of Iceland came from England and what is now France. Some were probably captured and carried off in Viking raids only 40 generations ago.

At The Night Time
Paint it black and paint it red,
And like a nice flow with your brush;
But use it at the night time like,
An Australian in bed!
Genetic information,
Positive or negative is considered by a person's character!
But your choices can affect your life, your family and your community;
And like a cat out of the sack.

It's funny, to me, the way people refer to childbirth as a miraculous event. A miracle is something that defies nature. Only, childbirth has got to be the most natural thing in the world. Top three anyway. But, on the other hand, when you think about it, there's really no other word that fits. Sperm. Egg. A coincidental meshing of genetic information that will grow something that could write an opera or cook up some Napalm. It blows my mind.

Out Gunned By A Single Cell DNA Rocker
Amoebia Dubia approximately
200 times more DNA than a human
being of ego essential character.
Genome human 3.2 billion base pairs.
The largest sequenced genome known?
At present a one celled animal traveller.
Counting up in genome base pairs we have
E. coli 4.1 million, baker’s yeast 12 million,
a worm 97 million, a fruit fly 120 million base pairs.
Continuing with our count up define
a flower arabidopsis (Arabidopsis thaliana) 157 million,
a bat (Rhinolophus ferrumequinum) 1.9 billion,
a snake (Boa constrictor) 2.1 billion
an Asian barking deer (Muntiacus muntjak vaginalis) 2.5 billion
us humankind (Homo sapien) 3.2 billion
a frog (Bufo bufo) 6.9 billion
amoebia (Amoebia proteus) 290 billion
amoebia (Amoebia dubia) 670 billion base pairs.
Amoebia Dubia approximately
200 times more DNA than a human
when the human genome was
recorded as 2.9 million base pairs.
Human immunodeficiency
virus type, only 119,750 thousand?
A virus usually contains
less base pairs than a bacterium.
“Duplications are probably
fundamental to the creation
of genetic novelty.”
“Horizontal gene transfer is a highly
significant phenomenon and amongst
single-celled organisms perhaps
the dominant form of genetic transfer.”
“Horizontal gene transfer is invoked
to explain how there is often extreme
similarity between small portions
of the genomes of two organisms
that are otherwise very distantly related.”
The words probably, perhaps and invoked
were used to indicate that we are not as knowledgeable
nor smart as collective public perceptions.
Artificial horizontal gene transfer
is a form of genetic engineering
which was once used for genetic warfare
biological weapons development
crossing the genetic barrier between
species to create a cold war advantage
such as the creation of the aids virus.
While the human race continues to deploy
scientific development to attain military supremacy
Amoebia Dubia continues rein supremacy
as the largest sequenced genome known to humanity.
Amoebia Dubia slam dunks the field and rocks on.

How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.

Where are the intelligent people?
I agree with everyone that we are over populated,
Because we have our genetic pool intact,
We have never believed in the Eugenic Movement,
that promoted the selective breeding in human,
Thousands of human were sterilized in Europe,
For they had the low IQ, as if the IQ is genetic,
Millions of men and women were slaughtered in the wars,
As the dictators trusted the inferior genes in holocaust,
Human are manipulated to live the life of single,
In the name of the son and his cross and struggle,
If the men are clever, Catholics force them to be the priests,
If a girl is beautiful and intelligent, she is sent to nunnery,
The good genes of Europeans are lost in their beliefs,
The good genes of Europeans are lost in their misbehavior,
They need the people, who have good genes in their brains,
To do the programming and to run their everyday life,
We run for it leaving our loved ones behind,
We are the coolies in their land, still proud to say that.
