DNA is Deoxyribonucleic Acid.
It is basically 4 blobs which stick to each other to form a long chain of blobs. Each blob has a sugar in the centre (decoys ribose sugar), this sugar is a pentagon shape and has 5 corners. DNA has a phosphate attached to the sugar in one corner and a nucleotide attached to the sugar in the opposite corner. The nucleotide determines if its called A, T, G or C (there are only 4 possibilities).
The sequence of A,T,G and C down the long chain (about 3mtrs long in a human) determines different genes, one gene may be 12 nucleotides long, another may be four. Each gene is responsible for making your appearance (phenotype), there are 25000 genes in the human body divided (not equally) into 46 chromosomes.
But, because 23 chromosomes are from mum and 23 are from dad, there are only 23 paired chromosomes, each gene is therefore duplicated or shown twice, this is called a diploid cell. IN sex cells such as egg and sperm, there are no duplicates and there are 23 single chromosomes, this is called a haploid cell.
Hope this helps, I use these answer websites Lot and find them really useful.
Chromosomes are made of protein and DNA.
Molecules. DNA is a big molecule made by smaller molecules. http://en.wikipedia.org/wiki/DNA
Genes are the units of heredity, and are made up of segments of DNA
Proteins are made using DNA. DNA is stored in nucleus
The Dna letter is a nucleotide base. It is made from a series of nucleotide base substrates.
Is coral made of DNA

That's correct! Chromosomes are composed of DNA and proteins called histones, which help to package and organize the DNA. These structures are found in the nucleus of a cell and play a crucial role in carrying genetic information from one generation to the next.
the first dna model was made in 1953 by james watson
