DNA by ValdesBG DNA by ValdesBG
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
Chemically, DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription.
Within cells, DNA is organized into long structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms (animals, plants, fungi, and protists) store most of their DNA inside the cell nucleus and some of their DNA in organelles, such as mitochondria or chloroplasts.[1] In contrast, prokaryotes (bacteria and archaea) store their DNA only in the cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA. These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.

There are way too many base pairs per turn of the helix. Average is ~10.

Amazing pieces of organic technology. Makes me wonder if life where to evolve on other worlds what system of information storage it would use.

Really nice XP can you do it molecular wise now?

what do you mean?
I`m sorry I have some problems with translating from English to Bulgarian.

I mean that instead of using like you have here a stick to represent the various components of DNA you would form the chemical structure instead

Okay, now I've had my biology lesson for the day . . . ;)

Very well done, although I doubt the real stuff is quite as colorful, this is a neat rendition.

Of course the real DNA is not so colorfull. In fact there is no colors at all, cuz who can tell what colors have atoms and molecules. As you can see against blue there is always yellow, and against red there is always green. As it`s A-T and G-C complementary bases.

That was my point in making.

Thank you for your comment :)

Thank you, my friend.

If you have some other ideas for rendering - write to me :)
