Buckle up and get ready to learn about DNA!
What is DNA?
DNA is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.
Where is DNA?
DNA located in the nucleus, humans and other complex organisms also have a small amount of DNA in cell structures known as mitochondria.
What is DNA made of?
DNA is made of chemical building blocks called nucleotides.
What is DNA's structure?
DNA is a double-helix formed by base pairs attached to a sugar-phosphate backbone.
What does DNA do?
DNA contains the instructions needed for an organism to develop, survive and reproduce.
Heredity
DNA has traits which are passed from parent to child which is heredity.
Replication
DNA replication is the process of producing two identical replicas from one original DNA molecule.
Protein Production
The role of DNA is to serve as the blueprint for amino acid sequences to make proteins.
What is RNA?
RNA is a messenger carrying instructions from DNA for controlling the synthesis of proteins.
Types of RNA
Messenger RNA
Transfer RNA
Ribosomal RNA
What does RNA do?
RNA fits through the pores of the nuclear membrane, unlike the DNA, allowing it to transport all of the information to the specific parts.
