• sugar- deoxyribose

• nitrogenous base

In the figure below, what do the pentagons (shape like a house) represent?

• phosphate group

• sugar- ribose

• sugar- deoxyribose

• nitrogenous base

What in the DNA determines which proteins are made?

• the order of the bases

• the shape of the chromosome

• the shape of the DNA molecule

• ribosome / cytoplasm

• cytoplasm / nucleus

• nucleus/ cytoplasm

During translation, the type of amino acid that is added to the growing polypeptide depends on the
