DNA+(Questions+3&4)

3. How and why does DNA copy itself? A) DNA copies itself so each cell is formed in the right genetic order and that the cells have the correct genetic information to function. B) Each DNA strand unwinds and splits into "daughter strands". Since Thymine only bonds with Adenine and Cytosine only bonds with Guanine, the new strands are the exact replica of the old strand. While the parent strand is splitting, the missing half of each daughter strand forms and starts to combine with the daughter strand. The daughter strands splits again when they are fully formed. This process repeats itself many times. media type="file" key="dna-rna2.swf" width="360" height="270" Link: []  4. What are genes and where are they found? A) Genes are traits that children inherit from their parents. It could be parts of your personality, intelligence, bone structure, eye color, or hair color.   B) Genes are made up of DNA, and DNA exists in basically every cell in your body, Therefore, genes are in every part of your body.
