Q1. What is DNA and where is it found? A1, DNA is deoxyribonucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. DNA is found in the nucleus. Chromosomes are made in the DNA and are also found in the nucleus/

** Q2. What does it look like (its structure) and what is it made from? **

**A2, DNA is a double helix. One helix is a strand or a half of the DNA. The whole DNA structure looks like a spiral stair case. DNA is made out of Hydrogen, Nitrogen, Deoxyribose sugar, carbon, and phosphorus.**



**Q3. How and why does it copy itself?** DNA is all coiled up inside chormosomes. It first has to unwind and then unzip itself. Unzipping exposes the nitrogen bases on both sides of the DNA molecule. New nitrogen bases on both sides of the DNA molecule. New nitrogen bases in the nucleus attach themselves to the exposed nitrogen bases and you end up with two completely new stands of identical DNA that then rewind themsleves.

DNA replication occurs during interphase when the cell is getting ready to undergo cell division (makes new cells). Those new cells each need a complete a new set of DNA so they hace all the neccessary information to carry out the proccess they need to do. **A3, DNA copies itself when the two sides of the DNA molecule unwind and unzip. Then it creates a new strand for each side. It copies itself because it needs to pass the DNA to the next cell so it can function properly.**



** Q4. What are genes and where are gene? **

**A4, Genes are the set of information that controls a trait. It is a segment of** **DNA **** on a chromosome that codes for a specific trait. **
