DNA

Sure.... can I explain the most basic of DNA?

AT and CG

There are 4 DNA bases. Same 2 are paired together, simple.

AT or TA . . . . CG or GC
A and T together. C and G together. 4 make 2 each time, stacked like dominos.
The combination of 4 run along like endlessly two base pairs wide.

A two-sided chain:
DNA= ATCGCGTAATGG ect and ect..... These 4 in varied combination, two wide.
. . . . . . TAGCGCATTACC

This is it. The 4 make 2 when side by side.
DNA is a 2 sided chain of 4 molecules, T A G C varying length ways.
RNA is one strand like a train.AU and CG. The T is replaced.

The Nucleic part of DNA means the center of the cell.
The D means sugar and A means acid. Can I keep it simple?
Each 2 bases turn-over left-to-right to be on other side. AT or TA.
The 2 stack on eachother when length ways. Do you see it?

To go into RNA, to make a long story short, it's a copy of a portion
of DNA. A short section of DNA is copied and then this copy
moves out of the nucleus to help make proteins.

The DNA stacks like dominoes and are connected by sugar and phosphate.
Thats the rebos in DxrebosNA. Its outside connected to the bases.
Then there is a phosphate molecule between each sugar.

I just read in a book that most amino acid is made in the liver.

RNA

I want to get into RNA. There are mRNA, tRNA, anyway they are short single
strands almost like DNA. RNA has one different base and an extra oxygen.
AUCG ect . . .for a short length.

see this book: [ DNA The Ladder of Life ] ; 576.3 page 112 about tRNA.
It shows tRNA in the nucleus. Where do they come from ?

One sided string
UGGUGAUGCU = mRNA

UGG GUA UCG= CODE / for attaching single amino acids.

This may not seem like a new idea. In the last 2 years lots has gone
up on the Net. I have had Searches in some Search Engines but I think
lots more illustrations are available now. Lets say this is my 1-st.
tRNA from Google Search Engine. Maybe more subjects can
be explained now from Search Engines

This is the simplest diagram showing the P=Phosphorus and S=Sugar backbone
supporting the DNA bases. The Sugar molecule connected to the bases. You Got It !

As I teach, I can make reliable comments like about the movie industry. Notice
all the devil-like monsters they want to show children.

This picture shows DNA turned like a page in a book for bases to be on other side.
