Deoxyribonucleic Acid

Extracts from this document...

Introduction

Deoxyribonucleic Acid DNA is the blueprint for all life in all living things. DNA stands for deoxyribonucleic acid and is what Chromosomes are made of. DNA is a very large molecule (a polymer) and that it is made from smaller molecules called nucleotides which are monomers. There are many different types of nucleotides in a DNA molecule. ...read more.

Middle

These bonds link together each chain into a double helix which is like a ladder in appearance. The way this link together is called complimentary double base pairing e.g. one type of base attached to another. The DNA bases are what forms the genetic code. Three bases form one piece of the code and this is called a triplet code. ...read more.

Conclusion

A living cell can copy its own DNA but to do so it needs nucleotides, special carrier molecules, some energy and some specific enzymes. This happens in cell divisions such as Mitosis which occurs when an organism is producing more cells and it's own are being replaced. The DNA of a chromosome un-attaches itself from the double-helix and is replicated. This is when complimentary base-pairing comes in helpful and allows the cell to copy itself. Knowing how DNA works allows scientists to alter or replicate certain cells to endless uses. ...read more.
