In science, we are learning about the structure of DNA. DNA contains information for the cells. DNA looks like a double helix, a twisted ladder. When DNA has to make copies of itself, it unzips like a zipper and makes two DNA helixes and uses nucleotides to make it. DNA contains sugar and phosphate groups. Cytosine all ways pairs up with guanine Adenine always pairs up with thymine. DNA also contains hydrogen bonds.
What I learned was how DNA makes copies of itself and what DNA contains. The people who discovered DNA were James Watson, Francis Crick, Rosalind Franklin, Maurice Wilkins, and Erwin Chargaff. These people were the first to discover DNA. Rosalind Franklin was the first to discover DNA and two forms of it, A and B. She also made a photo that was a picture of DNA and was called Photo 51. She thought that DNA had a spiral shape to it.
