C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
Answer A)
The gene would not be transcribed. This is because the gene transcribing machinery would not be activated if the promoter sequence is not recognized. Transcription will not start.
Answer B)
The gene would not be transcribed. This will result in no RNA polymerase being formed. Hence, transcription and translation will not occur.
Answer C)
The mRNA would contain intron sequences, which would be translated into extra amino acids in the protein. A non- functional protein would be made.
