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

The number of hydrogen bonds that hold the strands of DNA together.
The number of hydrogen bonds that hold the strands of DNA together.

The number of carbons in the DNA molecule.
The number of carbons in the DNA molecule.

The sequence of nucleotide bases in the DNA molecule.
The sequence of nucleotide bases in the DNA molecule.

The sequence of phosphates along each DNA strand.
The sequence of phosphates along each DNA strand.

Answer: The sequence of nucleotide bases in the DNA

Explanation: The sequence of the nucleotides directly code for each trait. The genetic code is contingent on the sequence of the bases- if the order is changed (you will learn about this in genetic mutation), it would create a different code, which could possibly create a totally different gene depending on which base is changed.

Hope this helps,
