1. DNA vs. RNA

2. Review of DNA Double stranded molecule
Contained in the nucleus of the cell
Controls the actions of the cells
Made up of Nucleotides
Deoxyribose sugar
Phosphate group
Nitrogenous Base
A, T, C, G

3. What is RNA? RNA = Ribonucleic Acid Single stranded molecule
Can leave the nucleus and move around the cell
Made up of Nucleotides
Ribose sugar
Phosphate group
Nitrogenous Base
A, U, C, G
Uracil replaces Thymine

4. DNA vs. RNA DNA RNA NUMBER OF STRANDS LOCATION SMALLEST SUBUNIT
TYPE OF SUGAR
NITROGEN BASES

5. DNA vs. RNA

6. Types of RNA mRNA (Messenger RNA) rRNA (Ribosomal RNA)
created from DNA; carries the information contained in the DNA out of the nucleus to the ribosome
rRNA (Ribosomal RNA)
Helps make up the ribosome
tRNA (Transfer RNA)
Carries amino acids to the mRNA in the ribosome to help build a protein

7. What are Proteins?
Chains of Amino Acids connected to one another by peptide bonds.
Have a specific shape and function.
Examples:
Enzymes
Hormones
Antibodies
Hemoglobin
