DNA

Discovering what makes you, you.

What is DNA?

DNA is also known as Deoxyribonucleic Acid. DNA is located in the nucleus of all living cells. DNA is shaped like a winding staircase called a double helix. DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.

What does DNA do?

DNA carr­ies all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. During heredity, DNA actually controls the production of the proteins that determine all of the traits passed on from parents to their offspring. After replication, each daughter chromosome has one strand of newly synthesized DNA and one strand of DNA from the parental chromosome.

What does RNA do?

DNA makes RNA, RNA makes proteins and is involved as a carrier of information.RNA molecules also contain modified nucleotides, and in some cases, quite complicated ones

What is RNA?

RNA is also known as ribonucleic Acid, present in all living cells. RNA's job is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
