What is tRNA and its role/function

Transfer RNA (tRNA) is a short nucleotide RNA chain. With a L-shaped structure, tRNA functions as an 'adaptor' molecule that translates three-nucleotide codon sequence in the mRNA into the suitable amino acid of that codon. As the link between amino acids and nucleic acids, tRNAs determine the genetic code.

Explanation:

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.
