Which of the following is true of dna? there are six nitrogenous bases involved. cytosine can pair with guanine and adenine. there are four nitrogenous bases involved. adenine always pairs with guanine. which of the following is not true of dna? question 3 options: hydrogen bonds hold nitrogenous bases together. guanine always pairs with cytosine. each nucleotide is connected to three nitrogenous bases. adenine always pairs with thymine. dna and rna are very similar; however, rna does not contain adenine and thymine. question 4 options: true false which of the following is considered the "zipper" and separates strands of dna during replication? question 5 options: helicase isomerase lipase polymerase

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.

we are putting to many trash.
