The genetic code is essentially the same for all organisms. From this, one can logically assume all of the following EXCEPT... A. a gene from an organism could theoretically be expressed by any other organism. B. all organisms have a common ancestor. C. Viruses do not contain a genetic code. D. the same codons in different organisms usually translate into the same amino acids. E. different organisms use the same types of amino acids to make polypeptides.

Respuesta :

Ans.

Genetic codes are three letter symbols that represent three nucleotide base in genetic material and provide information to code a particular amino acid at the time of protein synthesis.

All living organism contain universal genetic codes, means different organisms have same codon for same amino acid. Viruses also contain genetic codes same as their host, which is required for proper viral protein synthesis.

Thus, the correct answer is 'option C). viruses do not contain a genetic code.'
