DNA Structure (Function)

Which statement is true, based on the picture below?

• The model is inaccurate because the base pairs are incorrect

• The model is accurate because it contains correctly paired bases.

• The model accurate because it shows each splitting to form a double helix

• The model is inaccurate because some typical bases in DNA are missing

Which 2 molecules forms the sides (backbone) of the DNA ladder?

• deoxyribose and adenine

• deoxyribose and a hydrogen bond

• sugar and the nucleus

• deoxyribose (sugar) and phosphate

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

How does DNA in cells determine an organism's complex traits?

• DNA contains codes for proteins, which are necessary for the growth and functioning of an organism

• DNA separates into long single strands that make up each part of an organism

• DNA produces the energy an organism needs to grow

• DNA folds into the nucleus of each of the cells organism
