Describing how the structure of DNA is suited to its role in Cell Division and Protein Synthesis.
DNA is found in every cell nucleus. The nucleus contains genetic codes, these codes decide a species inherited characteristics. Cell division is a process of replacing lost or damaged cells and aiding growth. To produce new cells proteins need to be manufactured this is done by a process called Protein Synthesis.
The role of DNA in these two processes is very important. DNA controls the manufacture of proteins and these proteins are what make us unique. Therefore it is important to understand the structure of DNA and how it is suited to its role in these two processes.
Structure of DNA
A strand of DNA is made up of a double helix. When it is unwound it consists of phosphate, sugar and one of four organic base/nitrogen molecules called nucleotides. The sugar and the phosphate form the two strands along the sides of the helix and the bases are joined by hydrogen bonds that form ties like rungs on a ladder.
