Review: Atomic Structure

What is the molecule from the previous slide?

What makes a biomolecule?

A monomer is a building block of biomacromolecules. 

Covalent bonds are molecular glue

Covalent bonds bond to monomers and form polymers

They take us from mono to poly.

Train car is to train as monomer is to ___

What are nucleic acids?

• Nucleic Acids are biopolymers necessary for all life. 
• They store genetic information and help synthesize proteins. 
• The monomers of nucleic acids are nucleotides. 

Examples of Nucleic Acids

• RNA and DNA are both examples of nucleic acids
• The spiral strucures are called helix
• Nucleobases are chemically bound to the sugar-phosphate helix
• Pairs of nucleobases, which are just simple molecules, are how nucleic acids store information. 

What is DNA?

• DNA is a type of nucleic acid located in the nucleus.
• DNA consists of 2 strands in a double helix.
• DNA replicates and stores genetic information. 

What is RNA?

• RNA converts the genetic material of DNA into proteins.
• RNA consists of a single strand of nucleotides. 
  
• RNA molecules are shorter and thinner the DNA molecules.

Nucleic acids, like RNA, store information on how to arrange amino acids into proteins, which make up cells.

How does RNA make protein?

• Special chemicals in the cells make partial copies of DNA called RNA. 
• RNA is transported out of the nucleus to the ribosome.
• The ribosome "reads" the RNA and uses it to arrange amino acids into proteins.
