Starter Questions What is the function of DNA? Stores information for making proteins Where are proteins made in the cell? On the ribosomes in the cytoplasm Can No DNA leave the nucleus? Then how can the information for making proteins get to the ribosome? RNA is made
Central Dogma
Vocabulary Terms • Chromosome : A rod shaped structure made of one strand of DNA and protein • Gene= segment of DNA on a chromosome that codes for hereditary trait (protein) • RNA (Ribonucleic Acid): an intermediate between DNA and proteins, made of nucleotides
Vocabulary Terms • Transcription: DNA acts as the template for RNA synthesis (Making RNA) • Translation: RNA directs the assembly of protein synthesis (making protein)
Central Dogma • Framework for understanding the flow of information • Information flows in the following way: • DNA RNA Protein

What differences do you notice between RNA and DNA?
RNA vs DNA RNA • Sugar = ribose • Uses uracil instead of thymine • Single stranded DNA • Sugar = deoxyribose • Use thymine instead of uracil • Double stranded
Double Bubble RNA vs. DNA
Types of RNA • Messenger RNA (m. RNA): single strand of RNA that carries information from DNA to ribosome
Types of RNA • Ribosomal RNA (r. RNA): RNA that is part of a ribosome
Types of RNA • Transfer RNA (t. RNA): transfers amino acids to the ribosome to make a protein
