DNA

• DNA is the genetic material. That's because our DNA determines our inherited features.
• What does DNA look like?


  Here it is, but in a picture.

  
• DNA consists of two strands, and each strand is a polymer. Basically, each strand is made by joining together lots of smaller molecules.
• In DNA, the two strands wrap around each other to form a double helix.
• A gene is a small section of DNA on a chromosome.
• What does a gene look like on a chromosome?


  Here it is, but in a picture.

  
• Proteins are made by joining together amino acids. Each gene encodes for a specific sequence of amino acids, to make a specific protein. Like this...

  
• The genome is the entire genetic material of an organism. So the human genome is the entire genetic material that makes a human.
• Understanding the human genome, will help us to search for genes that are linked to a disease. It will also help us to understand and treat inherited disorders. Lastly, we can use the human genome to trace human migration patterns from the past, this help to discover their own ancestry.
• DNA is short for deoxyribonucleic acid.
• DNA, is the chemical molecule that contains the instructions for growth and development of all organisms.
• • DNA is the genetic material that determines the characteristics of all living organisms.
  • DNA carries a set of chemical instructions to make all the proteins required for life.
  • Except for identical twins every person's DNA is unique.
• DNA is classed as a polymer (a molecule made from many repeating subunits called monomers)

  • Monomers are the small basic units that can make larger complex molecules.
  • In DNA the individual monomers are called nucleotides.
  • The nucleotides are joined together to form a single long chain/strand.
• Chromosomes are found in the nucleus of cells. Chromosomes contain the molecule DNA.

• DNA forms a double helix Like this image.


  Here it is...

  
• These are the pairs within the double helix.
