Biomolecule Posters

Working in a group you will research nucleic acids and create a poster to share with the class. Remember that you are teaching the class about this topic and you need to explain the topic in terms they will understand. Each group member must contribute.

“Nucleic Acids”

Content

 Describe the different functions and compositions of DNA, RNA, mRNA and tRNA.  In what cellular processes are these molecules involved?  Where are the nucleic acids located within the cell?  Describe the composition of nucleic acids.  Describe how nucleic acid polymers are constructed by dehydration synthesis and broken down into monomers by hydrolysis.  How are nucleic acids related to proteins, heredity, and inheritance?  Include a diagram showing the molecular structure of a nitrogenous base. An example of the molecular diagram is found to the right.

Key Terms

DNA (deoxyribonucleic acid), chromosome, RNA (ribonucleic acid), tRNA (transfer RNA), mRNA (mRNA), nucleotide, adenine, guanine, cytosine, thymine, uracil, double helix, sugar, phosphate, hydrogen bond, base, nucleotide, monomer, polymer
