Front

Which part of a DNA molecule is responsible for the direct doing of specific traits in an organism?

Back

The sequence of nucleotide bases in the DNA strand.

Front

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

Back

The sequence of nucleotides in DNA

Front

What is the significance of the nitrogenous bases in the DNA double helix?

Back

The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.

Front

The sequence of nitrogenous bases in DNA is most important for what?

Back

Providing the instructions for the traits of an organism.
