Which of the following is NOT a component of DNA?

• Deoxyribose

• Nitrogen Base

You can find DNA ONLY in...

• animals

• all living cells

• plants

• bacteria

What is the monomer for DNA?

• glucose or monosaccharides

• glycerol and fatty acids

• amino acids

• Nucleotides

What is the backbone of DNA made of?

• glucose and sucrose

• amino acids and lipids

• deoxyribose (sugar) and phosphate

• carbon and helium

What are the 4 nitrogenous bases?

• U T C G

• A T C G

• A C G R

• A T C P

Adenine always binds with

• adenine

• thymine

• cytocine

• guanine

Cytosine always binds with

• adenine

• thymine

• cytocine

• guanine

What is the shape of DNA?

• Double Circular

How is the genetic information in all living things different.

• Not all living things have a sugar-phosphate backbone.

• The sequence (order) of the nitrogen bases are different.

• Not all living things have ATCG as nitrogen bases.

• Bacteria have carbon bonds instead of hydrogen bonds to hold the base pairs together.

Differences in traits such as hair texture are determined by differences in-

• the location of sugar groups in DNA

• the sequence of nucleotides in DNA

• the number of nitrogenous bases in DNA

• the molecules attached to the phosphate in DNA
