DNA Structure and Function

The twisted ladder shape of DNA is known as a

• Double Helix
• Triple Helix
• Single Helix
• Triple Helix

Which of the following base pairs would be found in DNA?

• Adenine - Thymine

• Adenine - Cytosine

• Guanine - Thymine

• Cytosine - Thymine

How many different nucleotides are found in DNA?

• 3

• 5

• 4

• 1

The two parallel strands of DNA are kept together by:

• Ionic bonds

• Covalent Bonds

• Phosphodiester bonds

• Hydrogen Bonds

If I have 5 Adenines (A) on 1 strand of DNA ....

• I will also have 5 Cytosines on the other strand

• I will also have 5 Guanines on the other strand

• I will also have 5 Adenines on the other strand

• I will also have 5 Thymines on the other strand

The structure boxed in red is called a:

• Phospholipid

• Sugar

• Nucleotide

• Amino Acid

ATCGTGTGCAT will bind to

• ATAGATGACCA

• TAGCACACGTA

• AAAATCCTCTA

• TACCACACGAA

Adenine bonds with ______________.

• Guanine
• Thymine
• Cytosine
• Adenine

Guanine bonds with ______________.

• Adenine
• Guanine
• Cytosine
• Thymine

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy
