Scientists describe our genetic code as universal. With minor exceptions, all species use the genetic code shown here for replication, transcription and translation into proteins. How can scientists say this? What evidence do you see here that support the statement that the genetic code is universal? All BUT ONE could apply
A. All DNA contains the same four nitrogens vases, A-T, C-G
B. Combinations of the 20 amino acids combine to make proteins
C. Proteins are synthesized via transcription and translation at the ribosome
D. The four nitrogen bases of DNA combine is threes to produce only 20 amino acids

Answer:

Option A, B and D apply except C

Explanation:

All DNA contains the same four nitrogenous bases, A, T, C, G and these bases combine in threes to produce 20 amino acids which make proteins.

On the other hand, DNA is transcribed in the nucleus to mRNA transcript and then sent to the cytoplasm for translation. mRNA is then translated to proteins with the aid of the ribosomes. Thus making option C wrong.
