DAY 1
2
Journal Questions A question given to you every few days To be checked on Tuesdays during Eagle time – Mrs. Nedrow and Mrs. Mahan’s class go to other Bio teacher Turn all 6 in with test Receive 6 extra credit points (1/q)
3
Warm Up INDIVIDUALLY: – Create a thinking map to compare and contrast DNA to RNA. Where in the cell is it? What is it made of? Nitrogen Bases? Types
4
Warm Up In small groups: – Compare your thinking maps – Make changes to yours if you need to
5
RNA vs. DNA DNA Double stranded Deoxyribose sugar Bases: C,G A,T RNA Single stranded Ribose sugar Bases: C,G,A,U Both contain a sugar, phosphate, and base.
8
Protein Structure Made up of amino acids Polypeptide- string of amino acids 20 amino acids are arranged in different orders to make a variety of proteins Assembled on a Ribosome
9
Replication DNA double helix unwinds DNA now single-stranded New DNA strand forms using complementary base pairing (A-T, C-G) Used to prepare DNA for cell division Whole genome copied/replicated DNA makes new DNA
10
Transcription and Translation: An Overview (aka the Central Dogma) DNA RNA Protein Transcription Translation
11
Transcription and Translation Cells are governed by a cellular chain of command We call this the “Central Dogma” – DNA RNA protein traits Transcription – Is the synthesis of RNA under the direction of DNA – Produces messenger RNA (mRNA) Translation – Is the actual synthesis of a polypeptide, which occurs under the direction of mRNA – Occurs on ribosomes We’ll start discussing this process tomorrow.
12
Closing Write a short paragraph comparing DNA to RNA - types, locations, structure, etc. (Include the CENTRAL DOGMA) COMPLETE SENTENCES!
