| − | {{stub}}DNA, otherwise known as deoxyribonucleic acid, is a [[molecule]] that encodes the [[genetic]] instructions in pants and animals. All living creatures contain DNA, and the DNA of two creatures' offspring is a combination of its parents' DNA. DNA looks like two ladders twisted around each other. | + | {{stub}}DNA, otherwise known as deoxyribonucleic acid, is a [[molecule]] in a form of a double helix that encodes the genetic instructions for the development of living organisms. All living creatures contain DNA, and the DNA of two creatures' offspring is a combination of its parents' DNA. |

| − | Parts of DNA called genes give the instructions for the body to carry out its functions and give rise to things such as eye color, hair color, etc. Genes are packaged into chromosomes. Every person has 23 pairs of chromosomes, where one set is inherited from his/her mother and the other set is inherited from his/her father.
| + | Subunits of DNA called genes serve as the instructions for the body to carry out its functions and give rise to traits such as eye color, hair color, etc. Genes are packaged into chromosomes. Each individual has 23 pairs of chromosomes, where one set is inherited from his/her mother and the other set is inherited from his/her father. |

| − | DNA changes create differences between people. However, they can also cause diseases and sickness. | + | DNA changes account for variability in a population. However, they can also have clinical significance. |

| − | DNA makes [[RNA]] , which in turn makes [[Amino Acids]] that that are used to form [[protein]]s. These proteins are the building blocks of all living creatures. [[RNA]] can also be turned back into DNA, which is called [[Complimentary DNA]] or [[cDNA]]. | + | DNA is transcribed into [[RNA]] , which is in turn being translated into [[Amino Acids]] that that are used to form [[protein]]s which are the building blocks of all living creatures. [[RNA]] can also be reverse transcribed back into DNA, which is the called [[Complimentary DNA]] or [[cDNA]]. |
