The DNA molecule is a double thread, coiled into a helix. The genetically important constituents of DNA are four nucleotides
The total DNA in a human cell, if the DNA molecules of each chromosome were lined up end to end, would be some 6 feet in length
Each human individual is made up of several hundred million million microscopic cells (plus considerable noncellular material such as bone and water). Cells come in a variety of shapes and sizes.
So TNF do we have to multiply several hundred million million microscopic cells X 6 feet.X 1 or 4 ?

Thanks for your trivial question

Pete
Pete, before you explain any more DNA information to me...please remember that I was a molecular biologist...I appreciate the explanation though.

Just take the 6 feet and multiply it by the number of nucleated cells in the body (its an estimate) - remember, muscle cells are multinucleated, red blood cells are enucleated during hematopoeisis, etc.

There are varying estimates as to the number of cells in an adult, but lets use a common estimate of 10 trillion.

So, do the math - about 6 feet/cell x 10 trillion cells = how many miles? Now convert that to astronomical units. People are pretty surprised when they see how much there is. And even more interesting is the fact that each of those 10 trillion cells (with nuclei) have pretty much ALL the instructions for making a whole human. The entire instruction manual for a human is crammed into something as small as a cell nucleus. Talk about compression of information.
Sir tnf, There is some misunderstanding in here, I precised these infos were not my own.

I know from your replies that you aren't ( un deux de pique ).

Is it true that we have like 30 some feet of colons inside?

Pete

I see now pete...when you said 'not my own' I wasn't sure what you meant - at first I thought you were saying that your own cells didn't have 6 feet of DNA in them.

Not 30 feet of colons. The colon is generally used to describe the large intestine. We have many feet of small intestine, where most of the digestion takes place. The small intestine also has a tremendous surface area do to all the tiny fingerlike projections in it.

You reminded me of that night when two of my friends with whom I spent the night, talking philosophy completly nacked.
I don't know were it come from but my friends have a doc in their area and I have a poor PHD.

A PhD is a 'doc' in an area.

tnf, as a trust in your vast greatness of knowledge and wisdom

could they actually make a living T rex with nothing more than what they have got there ?

i mean growing it, would they grow the cell into an egg then wait for it to hatch ?

remind me of that south park sketch:

under pants > ? > profit

just

70 million year old meat > ? > T-rex

tnf, can you explain to me the "shell method" for finding a volume of a solid for a curve rotated along an axis?

I know Tnf,,,PHD is just my Initials.

Of course you didn't know it. Nobody but me...Well, not any more.

I just have a bac in psychosociology of communication.

Far from you my friend.

I wanted to study medecine and the likes but I was afraid of the dead people on whom I would have had to study on.

Why, are you in calculus right now?

2 x pi x integral (radius x height)

Coincidentally, one of my students just happened to be working on shell stuff in his calc class - which is the only reason I remembered a bit of that formula. The limit part is missing.

I have learned to never say 'never' - but with the technology we have right now, that I am aware of at least, no.

I'm going to ask my good friend, who has a PhD in reproductive biology that question though Chunk.

I'll get back to you with his opinion.

Yeah I know the formula, but I don't get the principle of how it works. Disk method is easy to picture, so I can just sketch the graph and get all the numbers I need. For the shell method I don't understand shit

I wish I could help you more. It has been a LONG, LONG time since I've done much applied calculus. I can help students with it if I am looking at their work with them and have some time to review the stuff...but I can't give you the specifics now.

I bet Nightshade could, though.

Aight, I'll have to just figure it out myself anyway, cause I need to see some illustrations of what is happening and my cal book has some good ones in it. Cheers anyway.

Should I have to reminded you...

No competion here allowed.

I appreciate your participation in this thread.

Thanks all

To all the people who don't speak friench: don't bother trying to use a translating application for what I wrote, it's special code.

It would be worst for the average English person to try to translate what you just wrote than it is for me to find the slang words or meaning of the icons in here.

What is it with you?
Quesé qui t'arrive?

I had to look it up, but the best way I can explain it is to point you back to the derivation of Riemann sums. Recall the approximating rectangles under a given curve? Well, you're just rotating them about an axis. I have to take off at the moment, but if you're interested I can go farther in to it later...

A riddle for ye children to ponder on...

On a small island in the middle of the ocean, there lives a tribe of people. The number of people does not matter - let's say fifty. Each person in the tribe has either blue eyes or green eyes. However, there are no mirrors on this island and the ocean is too murky so the tribesmen have NO way of knowing what color their eyes are. Furthermore, the capricious god the islanders worship has forbidden them to reveal to each other what color eyes they have. The islanders are devout and thus far have obeyed their god's command, so none of them know what color eyes they have.

One day their god tells them that all blue eyed people must kill themselves and if they do, all the islanders will go to heaven. However, if a blue-eyed person doesn't commit suicide, or if any green eyed person commits suicide or is harmed in any way, or if, during the process, any islanders communicate in any way, all the islanders will go to hell. The islanders believe their god, and after a time, they succeed in carrying out his command. Keeping in mind that the exact number of islanders is irrelevant, how do they do it?

Hints:

1) No, this is not a trick question.

2) The answer does not rely on a play on words.

3) The answer has nothing to do with genetics or reproduction

4) No, they can't just gouge out their eyes and look (green-eyes can't come to harm)

5) No, there is not just one blue-eyed islander (that would be a trick question)

6) Many people have suggested that the islanders could look at their own reflection in each other's eyes to determine what their own eye color is. Try this. It is not possible.

p.s: I do not know the answer, thats why i posted it

have fun solvin it and if you like it i will post others to

Everyone must punch every blue-eyed person they see, right in the eye. Trauma to eyes will darken the iris color and the blue-eyed people will become hazel- or brown-eyed.
No green-eyed people will be harmed, and there will be no blue eyes left.

Good day my friends.

Tnf, for the Human DNA Calculation Length…

10 Trillion Cells X 6 Feet,

60000000000000 feet = 11,363,636,363.636364 miles or
122.2477293 astronomical units.

1 AU = 149,597,870.691 kilometers or 92,955,807.2674332 miles.

Definition: An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an unperturbed circular orbit a massless body would revolve about the sun in 2*(pi)/k days (i.e., 365.2568983.... days), where k is defined as the Gaussian constant exactly equal to 0.01720209895. Since an AU is based on radius of a circular orbit, one AU is actually slightly less than the average distance between the Earth and the Sun (approximately 150 million km or 93 million miles).

Tnf is this correct? That mean a little more than 122 times the distance between the earth and the sun. Quite impressive.

Btw what is the measure of a chromosome? We measure them with something like ‘’amstrong’’unit?
Pete.

lol, molecular distances are often displayed in angstrom

1 angstrom = 1.0 × 10-10 meters

Well, I was close amstrong
angstrom same letters just not at the right place.

Thanks for the correction my friend.
