The antibiotic erythromycin disrupts protein synthesis by preventing ribosomal translocation (movement of the ribosome relative to the mRNA). It does not affect any other step in protein synthesis. Suppose you are doing a translation reaction in vitro and you add erythromycin just before the 3rd peptide bond is about to be made. You wait a few minutes and look at the ribosome. Circle the correct
a. The carboxyl end of AA #3 should now be covalently bonded directly to: (tRNA #2) (tRNA #3) (tRNA #4) (AA #2) (AA #3) (AA #4) (none of these).
b. Which tRNA will you find in the A site? (tRNA #1) (tRNA #2) (tRNA #3) (tRNA #4) (tRNA #5).
c. The tRNA in the A site will carry: (an amino acid) (a polypeptide) (neither) (either one)

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.

you know they are heterozygous for a trait because they have it as jj or jj.
