What is not true for genetic code?

  • A condon in mRNA is read in a non-contiguous fashion

  • It is nearly universal 

  • It is degenerate

  • It is unambiguous

Solution

A.

A condon in mRNA is read in a non-contiguous fashion

The general features of genetic code are:
(i) The genetic code is written in linear form, using the ribonuclotide bases that compose mRNA molecule as letters.
(ii) Each word of codon consists of three letters, ie, the codon triplet.
(iii) The genetic code inside the cell medium is said to be non-ambiguous.
(iv) The code is degenerate, ie, a given amino acid can be specified by more than one codons.
(v) The codon contains start and stops signals.
(vi) The code is said to be commaless.
(vii) The code is said to be commaless.
