THE BUILDING BLOCKS OF OUR BODIES
We have received 27 chromosomes from both our parents, which together form a double DNA strand, a helix. This DNA contains the building blocks of our bodies. One of the chromosomes holds the Usher gene, which contains the protein code for the production of a protein that we need for hearing and seeing well.
NUCLEOTIDES
The DNA is a long chain of building blocks, also called nucleotides (or bases).
At first sight, the DNA seems to be a random sequence of As, Cs, Gs and Ts, but the order of these letters is highly important. In fact, the order of the letters defines the genetic code and determines whether a good protein is produced.

DNA DATABASES
There are databases in which geneticists, scientists and specialists can consult all information about mutations, transcripts and gene locations. These databases are always searched through by gene name.
