Very simply put, a gene is a region of DNA that codes for a protein DNA is composed of 4 different nucleotide bases- guanine, adenine, thymine, and cytosine. A group of three of these is called a codon. A codon codes for a particular amino acid. A protein is composed of a chain of amino acids put together in the codons are in. Therefore the genetic information is the sequence of codons and by extension the sequence of nucleotide bases.

it is complicated but we recall the nucleus is a small spherical and helix is in dna. dna helix is actually made of reapeating units called nucleotides.
The double helix IS DNA - its what the spiral structure of the DNA is called. :) hope it helped
Genetic code of the cell is found in a long molecule known as DNA.
The cell membrane is a double-walled structure containing a cell's genetic code.
DNA is the genetic code
The secondary genetic code is the folding of protein.
