Why must cells be able to both transcribe and replicate their dna? the cell's dna must be transcribed before it can be replicated. new cells can only be created after transcription has taken place. transcription can be used when a cell is unable to replicate. replication creates new dna while transcription creates mrna.

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.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
