What's DNA All About?

Lets take some twists and turns into the DNA world.

What is DNA?

DNA is located in the cells nucleus, DNA also stands for deoxyribonucleic acid. The two DNA strands are known as polynucleotides, they are also composed of simpler units called nucleotides. Nucleotides are compounds consisting of a nucleotide linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA. The DNA's structure is a double-helix and has two strands running in opposite directions. DNA is like a blueprint, takes your genes and gives your body directions to formulate it into physical appearance. It is the Molecular Basis of Heredity. DNA replication is the process of producing two identical replicas from one original DNA molecule. In order for DNA molecules to make a protein, a cell must put a chain of amino acids together in the right order.

What Is RNA All About?

RNA is a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. There are actually several types of RNA, but most RNA falls into one of three categories:

-Messenger RNA

-Ribosomal RNA

-Transfer RNA
