DNA and It's Properties
"You can't run away from your DNA!"
What is DNA?
Dioxyribonucleic Acid - commonly known as DNA - is the blue print for all living organisms. DNA is located inside of a cell's nucleus. These molecules are double helixes - two strands twisted around each other like a winding staircase. Each strand is made up of connected nucleotides (subunits of DNA.) These nucleotides are made of three parts: a phosphate group, a five-carbon sugar molecule and a nitrogen base.
About DNA
What does DNA do?
DNA creates genes. Genes give your body instructions on how it should grow. DNA does many things in its' cycles like heredity, replication, and protein reproduction.
DNA Replication
DNA Replication is the process of producing two identical replicas from one original DNA molecule.
Heredity
Heredity is the passing on of physical or mental characteristics genetically from one generation to another.
Protein Production
Protein Production is the work of RNA strands being decoded and which later forms proteins.
What is RNA?
RNA is ribonucleic acid, a nucleic acid that is present in all living cells. Its role is to be a messenger to carry instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
mRNA
Messenger RNA that travels from nucleus to ribosomes with a coded protein message
tRNA
Transfer RNA where RNA collects, transfers, and positions amino acids to make a protein molecule.
rRNA
Ribosomal RNA where RNA is a part of the ribosomal structure.

The Double Helix Game!
This a game that is a bit difficult for me, but if you are really fast with your mouse and/or your brain, this is the game for you!
