The circle represents the ​ (a)   . The pentagon represents the ​ (b)   . The A, G, C, and T represent the ​ (c)   .

• phosphate
• sugar
• nitrogen bases
• calcium carbonate
• RNA
• DNA

DIRECTIONS: Continue going through the interactive activity. When you get to the screen where you build a complementary strand of DNA, answer this question.

QUESTION: Match the following to the best match

• Cytosine

• Type of bond between nucleotides

• Covalent

• Guanine pairs with

• Hydrogen

• Adenine pairs with

• Thymine

• Type of bond between bases

DIRECTIONS: When you have built your molecule of DNA and you see the "Well Done!" screen, answer this question:

QUESTION: What is DNA's backbone made of?

• sugar and bases

• sugar and deoxyribose

• phosphate and bases

• sugar and phosphate

Draw a picture of DNA.

Label the phosphate, sugar, and the four bases.

Make sure you include the two strands of DNA and that your bases match with their complementary bases.

DIRECTIONS: When you get to the final screen with your score and it gives you the option to email your teacher or take a screenshot, TAKE A SCREENSHOT by clicking ctrl, shift, and the windows button above #6. You can either copy and paste your screenshot onto this Draw It activity, or attach it on Google Classroom.
