DNA Structure

For the past week in biology we have been learning and understanding about the structure of DNA(Deoxyribonucleic Acid) the geneic material inside all cells, and what each part was. DNA consists of sugar, phosphate, nitrogenous bonds, hydrogen bonds, and A, T, C, and G. The ladders that make up the DNA structure is called nitrogenous bases: A stands for Adenine and it is always paired up with T or Thymine. The same can be said for C(Cytosine) and G(Guanine). The ladder shape twists into a way that it forms a double helix.  The arrangement of two bases in the DNA molecule forms a base pair and each base pair is held together with a weak bond called a hydrogen bond. The subunit  of DNA has three parts: a phosphate  sugar, and nitrogenous bases these all together are called a nucleotide. Then when DNA makes a copy of its self its called replication.

The above picture is one that my group drew in class to show that we knew the structure of DNA and the terms that go along with it. On the drawing the triangle shape is sugar. The purple lines are phosphates. The brown circle in between the base pairs are known as hydrogen bonds. The yellow base is the  C (cytosine) base. The red base is the T (thymine) base. The black base is the G (guanine) base. The blue base is the A (adenine) base. The subunit of DNA has three parts: a phosphate, a sugar, and a nitrogenous base. This is also known as a Nucleotide. The backbones of the DNA molecule are made of alternating sugar and Phosphate bonds. The scientific name for the DNA molecule is called the Double Helix.
