DNA Structure and Function 2020

Which of the following is not a component of DNA?

• 5 Carbon Sugar
• Phosphate Group
• Carbon Base
• Nitrogen Base

Which of the following is not a nitrogenous base found in DNA?

• Thymine

• Uracil

• Guanine

• Adenine

According to Chargaff's rule, Cytosine always pair with

• Adenine
• Uracil
• Thymine
• Gaunine

What is the significance of the sequence (order) of the Nitrogen Bases in DNA?

• The order of the Nitrogen Bases determines the number of chromosomes present in an organism.
• The order of the Nitrogen Bases determines the traits that an organism will possess (have).
• The order of the Nitrogen Bases determines the gender of an organism.
• The order of the Nitrogen Bases determines whether an organism is abiotic biotic.

The twisted ladder shape of DNA is known as a

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

Assume that you have straight hair and your sibling has curly hair. What accounts for this difference?

• You have DNA and your sibling does not.

• Your sequence of nitrogenous bases in the gene for hair texture is different than your sibling.

• Your sibling has no genes for hair texture in their DNA.

• Your sibling has a genetic mutation.
