Understanding DNA Deoxyribonucleic Acid

What did Rosalind Franklin do? _________________ _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________

What James Watson & Francis Crick figure out? _________________ _________________ _________________ _________________ _________________ _________________ _________________ _________________ _________________ _________________ _________________

What did Erwin Chargaff discover? AT C G _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________

examples: DNA and RNA sugar phosphate nitrogen base nucleotide Are made up of _________________________ What are the three parts of a nucleotide? ___________________________ Nucleic acids store _________________________

Label the Nucleotide ___. Sugar (deoxyribose) ___. Phosphate Group ___. Nitrogen Bases A B C

Rules for Base Pairing in DNA: Cytosine always pairs with ___________________________ Adenine always pairs with ___________________________

*_______________________ ______________________ ______________________ ______________________ ______________________ ______________________ ______________________ What is the function of DNA ?

Sugar Phosphate Nitrogen Bases Fill in the base pairs. Remember your base pair rules.

Label: -Sugar-phosphate backbone -Base -Hydrogen bonds

Fun Facts If you wrote down all of the bases in one cell, you would fill a stack of 1,000 phone books with A's, T's, G's and C's

Fun Facts If you unraveled all your chromosomes from all of your cells and laid out the DNA end to end, the strands would stretch from the Earth to the Moon about 6,000 times.

Understanding RNA Ribonucleic Acid

Label the RNA Nucleotide ___. Sugar (ribose) ___. Phosphate Group ___. Nitrogen Bases A B C

Rules for Base Pairing in RNA: Cytosine always pairs with ______________________________ Adenine always pairs with ______________________________ What base that is in DNA is NOT in RNA? ________________________

* Helps make ___________________ Types of RNA A. ______________ (mRNA) B. ______________ (tRNA) C. ______________ (rRNA) What is the function of RNA?

__________________ __________ Label: -Base -Ribose -Phosphate group
