In the is firmed from free floating nucleotides in a process called this process requires the enzyme

In the nucleus, mRNA is formed from free floating nucleotides in a process called transcription. This process requires the enzyme RNA polymerase II.

Explanation:

mRNA (or messenger RNA) is transcribed from a DNA template in the nucleus. This uses the enzyme RNA polyermase II, which copies the DNA sequence to the RNA sequence using nucleotides. The RNA polymerase binds at gene promoters, where it transcribes the RNA by reading the DNA sequence until it reaches the termination signal to stop transcribing.

After this, the RNA molecule moves to the cytoplasm where it can be translated into protein.

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.
