Transcript
Name:___________________________________________ Date:_____________________ Period:______ DNA KEY Part I: DNA Structure 1. Label boxes a-d using the terms: Nitrogen base, Nucleotide, Deoxyribose (sugar), and Phosphate. Use your DNA Guided Notes. c. Deoxyribose (Sugar) a. Nitrogen base T C d. Phosphate b. Nucleotide C T 2. Fill in the missing bases on the DNA molecule above. Remember how they pair. Part II: DNA Concept Map Fill in the concept map with the correct terms. Use your DNA Guided Notes. 1. Adenine (A) DNA is made of 4 nitrogen bases 2. Thymine (T) 3. Guanine (G) 4. Cytosine (C) It is in the shape of a Double helix The sides of the ladder are made of Phosphate The steps of the ladder are made of nitrogen base pairs Sugar A pairs with T G pairs with C Assignments Name:___________________________________________ Date:_____________________ Period:______ Part III: How Does DNA lead to Traits? Directions: 1. Read the boxes and fill in the missing words. Use your DNA Guided Notes. 2. After, color code the DNA molecule using the key below. The specific order of bases along a DNA molecule forms a “word.” This is called a G E N E When the ribosome reads this word it is able to make a P R O T E I N This protein gives an organism a specific characteristic called a T R A I T blue purple red orange yellow green If a portion of the DNA is changed we call this a MUTATION This change is a “spelling mistake.” Will the cell be able to make the correct version of the protein: YES or NO? NO COLOR CODE THE DNA MOLECULE Assignments
