*DNA

The “steps” of the DNA ladder are made up of:

(a)  

• nitrogen bases bonded together
• sugar and phosphate molecules
• amino acids
• carbon and oxygen

The sides (or handrails) of the DNA ladder are made up of

• nitrogen bases bonded together

• amino acids

• deoxyribose sugar and phosphate molecules

• carbon and oxygen

What splits apart the two sides of the DNA ladder?

(a)  

• the enzyme helicase
• amino acids
• glucose
• deoxyribose

The job of mRNA is to

• make amino acids

• carry the code from the DNA in the nucleus to the ribosomes

• make proteins

• carry the code from the ribosomes to the nucleus

What is a gene?

(a)  

• a section of DNA that contains the code to make a specific protein
• blue pants
• a protein made of amino acids
• the part of the cell that does photosynthesis

Which organelle reads the code and puts together the building blocks of proteins

• ribosome

• mitochondria

• endoplasmic reticulum

• golgi bodies

Our traits (eye color, freckles...) are determined by the kinds of (a)   made by our cells.

• proteins
• fats
• glucose
• carbohydrates
