What Does DNA Stand For?
DNA stands for DeoxyriboNucleic Acid (pronounced dee-oxy-rye-bow-nu-clee-ik acid). It is the genetic material of a cell.
What Is The DNA Structure?
The chromosomes inside the nucleus (control centre) of the cell are made of DNA. Lots and lots of DNA. It is very fine and tightly coiled but there may be as much as a metre in a single cell. DNA is really a code. It is divided up into sections. These sections are genes, which carry all the instructions for making up our body. So there is a gene that tells the body to have brown hair and so on. Each gene is a code for a particular protein. Our bodies are made up of proteins. So the genes dictate how we are made and what our bodies look like.
What Are The 4 Bases?
Here are four different types of nucleotides found in DNA, only in the nitrogenous base. The four nucleotides are given one letter abbreviations as shorthand for the four bases.
Where Is DNA Found In The Cell And In What Form?
In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome.
During DNA replication, DNA unwinds so it can be copied. At other times in the cell cycle, DNA also unwinds so that its instructions can be used to make proteins and for other biological processes. But during cell division, DNA is in its compact chromosome form to enable transfer to new cells.
Who Discovered DNA?
In 1951, James Watson and Francis Crick started work on unravelling the structure of DNA. It was known at the time that DNA was present in the nucleus of every living cell, and that it had something to do with heridity, but without a knowledge of its structure little more could be understood about how it actually worked. Their task was to devise a structure which would account for all the chemical and X-ray evidence, and at the same time be consistent with all the structural features of the units involved - such as the size and shape, bond angles and lengths, configurations and conformations.
What Is Amino Acids?
A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure. They also play a key role in the transport and the storage of nutrients. Amino acids have an influence on the function of organs, glands, tendons and arteries. They are furthermore essential for healing wounds and repairing tissue, especially in the muscles, bones, skin and hair as well as for the removal of all kinds of waste deposits produced in connection with the metabolism.

- A is for adenine
- G is for guanine
- C is for cytosine
- T is for thymine
