Which of the following is not a true statement regarding the genetic code? A. The genetic code is nearly universal, with only a few minor exceptions.
B. The genetic code is nonoverlapping.
C. The genetic code is degenerate.
D. The genetic code is triplet-based.
E. Each codon represents a different amino acid.

E. Each codon represents a different amino acid.

Explanation:

The genetic code refers to the set of rules guiding the translation of nucleotide bases in DNA or RNA into an amino acid sequence (proteins). The genetic code contains all the codons in the genome, which is a group of three nucleotide base (triplet-based). Each codon species a particular amino acid, however, more than one codon can code for a particular amino acid. This characteristics of the genetic code is called DEGENERACY.

The genetic code is said to be nearly universal because the same codon encodes the same amino acid in almost all living organisms with only few exceptions. The nonoverlapping nature of the genetic code refers to the fact the three bases of a codon are read independently from the bases of another codon i.e. codons do not overlap.

A codon represents one amino acid but more than one codon can represent the same amino acid. Hence, option E is untrue

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
