Pick up a concept map and start working Day 07 Warm up Pick up a concept map and start working

The 4 nitrogen bases are: DNA Structure and Function Study Guide Function is to store Stands for DNA Genetic Information Deoxyribonucleic Acid Found in all Model of DNA was developed by: Made up of repeating sub-units called but only in the Watson and Crick Cells Nucleus of eukaryotes Looks like a “twisted ladder” or Nucleotides Sides of the ladder are made up of alternating Double Helix which have 3 parparts: Phosphates and sugars The rungs or “steps” of the ladder are made up of Nitrogenous Bases The 4 nitrogen bases are: Hydrogen Bonds Form between bases Base Pairing Rules : Guanine only pairs with Adenine only pairs with Thymine Cytosine

Page: 31 Title: Transcription EQ: How are DNA and mRNA involved in the process of transcription? Standard: Explain the purpose and process of transcription and translation using models of DNA and RNA.[BIO.6C]

Only dealing with this part today! Central Dogma Only dealing with this part today! DNA mRNA Protein Translation Transcription Nucleus Ribosome

Makes body structures- Muscles, bones, etc Makes body structures- Muscles, bones, etc. Enzymes Used to transport large molecules across the cell membrane

Transcription Transferring information from one form to another Speaking To Writing Same information, different form

English to Spanish

DNA mRNA Same information but a different form first step in making a protein (polypeptide) occurs in the nucleus

Messenger RNA (mRNA): carries instructions from DNA to the rest of the cell

Ribonucleic Acid What is RNA? Analyze this RNA structure Talk with your partner and decide how this is different than DNA

U T DNA & RNA Differences: 1) RNA has ribose instead of deoxyribose 2) RNA is single stranded 3) RNA has uracil instead of thymine U T

DNA-Instructions for EVERYTHING

RNA – Partial Instructions

Copy this into your notes!! DNA to DNA DNA to RNA C  G G  C T  A A  T C  G G  C T  A A  U

What’s the point? genetic information (DNA) is turned into a Protein DNA is just the information, our useful product is our protein

Transcription Recap (big ideas) Is the first step in making a protein (polypeptide) Occurs in the nucleus DNA is used to make RNA RNA has U instead of T RNA is then sent out into the cell to make proteins It’s usually just a section of the DNA strand (gene) that codes for one specific protein
