Which of the following are not correct for of genetic code?

(A) The code is degenerate
(B) The codon is triplet. There are 64 codons which code for amino acids
(C) The codon is read in a contiguous fashion
(D) The code AUG has dual functions. It codes for methionine and also acts as terminator code

Choose the correct answer from the options given below:

(B) and (D) only

The correct answer is Option (4) → (B) and (D) only 
The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins by living cells. It determines how sequences of nucleotide bases (adenine [A], cytosine [C], guanine [G], and thymine [T] in DNA or uracil [U] in RNA) correspond to amino acids, the building blocks of proteins.

The salient features of genetic code are as follows:

The codon is triplet. 61 codons code for amino acids and 3 codons do not code for any amino acids, hence they function as stop codons.

(ii) Some amino acids are coded by more than one codon, hence the code is degenerate.

(iii) The codon is read in mRNA in a contiguous fashion. There are no punctuations.

(iv) The code is nearly universal: for example, from bacteria to human UUU would code for Phenylalanine (phe). Some exceptions to this rule have been found in mitochondrial codons, and in some protozoans.

(v) AUG has dual functions. It codes for Methionine (met) , and it also act as initiator codon.

(vi) UAA, UAG, UGA are stop terminator codons.
