3.16 DNA and Genetic information

• The chromosome are likely to contain 1000's of genes. We would expand the geneloci.
• We would find double helix when we expand, the would appear to be parallel.
• Then we expand again, we would see the two sides that are holding which is known as "sugar-phosphate backbone". There are no chemical it.
• In the base there are 4 letters that are stand for A (adenine) that pairs with T (thvmine) and another pair is C (cvtosine) that pairs with G (guanine).
• The order of the bases we call the gene. So, the gene is  the order of the bases of 1 side of double helix.

* What is the other side of the double helix be if the other side is "gene"?
