3.16 DNA & Genetic Infomation

Describe a DNA molecule as two strands coiled to form a double helix, the strands being linked by a series of paired bases: adenine (A) with thvmine (T) and cvosine (C) with guanine (G)



1.  In the chromosome, we find 100's of genes. Looking at one position on the chromosome called the gene loci, we find a double helix, in which is parallel.

2. Looking closer into the double helix, there are two strands holding it together. They are called "sugar phospate-backbone." In the middle we find a group of molecules called basis, and there are four "adenine (A) with thvmine (T) and cvosine (C) with guanine (G)"
3. The basis are holding together the two helix's, they do this by being paired up between 4 bases called: adenine (A) with thvmine (T) and cvosine (C) with guanine (G).
4. The order of the basis is always the same. But is different to each side. The order, is what makes up the GENE.
A
C
T

question: what makes up the protein?
