Question

4 why is the order of the nitrogenous bases in dna important?
a it allows the cells to alphabetize proteins
b the order of the bases codes for genes that code for traits in an
organism
c the order of the bases alters the structure of dna.
d nitrogenous base order affects changes in the shape of the alpha helix

Explanation:

DNA's nitrogenous bases (A, T, C, G) sequence forms genes. Genes carry genetic info. This info is transcribed and translated to make proteins. Proteins determine traits like eye color. So, base order codes for genes (and thus traits).

• Option A: Cells don't "alphabetize" proteins. Proteins are made via gene expression (transcription - translation), not alphabetizing.
• Option C: DNA structure (double - helix) is mainly due to sugar - phosphate backbone and base - pairing (A - T, C - G) rules, not base order.
• Option D: Alpha - helix is a protein structure (secondary structure). DNA has a double - helix structure.

Answer:

B. The order of the bases codes for genes that code for traits in an organism
