A partial diploid E. coli cell was created with the following genotype: it pozi yt /pf oʻzty Under which conditions would both b
eta-galactosidase and permease be produced? A Both beta-galactosidase and permease will be made constitutively, since one DNA strand has a mutant operator and therefore cannot be repressed by the lac repressor. B. The only conditions where this will happen are low glucose and high lactose levels. C. There won't be any conditions in which both beta-galactosidase and permease are made, since the lacy gene on the strand of DNA with a functional promoter is mutant. D. Neither beta-galactosidase nor permease will ever be produced, because the super repressor will always bind the operator to prevent transcription of lacZ and lacy.
c) There won't be any conditions in which both beta-galactosidase and permease are made, since the lacy gene on the strand of DNA with a functional promoter is mutant.
Explanation:
As per the given data the first strand does not have the promoter (p-). so RNA polymerase cannot bind to that strand to make any transcript. Then coming to the second strand , it does not have a Lac Y gene (Y-). Though the presence of super repressor has no effect on operator (o-), it can no longer bind to the operator, the genes would be expressed continuously but, lac y gene expression wont be there.
so the answer is option c There won't be any conditions in which both beta-galactosidase and permease are made, since the lacy gene on the strand of DNA with a functional promoter is mutant.
Gneiss is what happen when a
granite is put into high pressure temperature, during the Permian period,
sedimentary bedrock in the Appalachian region was subjected to high temp and
pressure. Rocks which contain many minerals ex: granite is called polymineralic.
The answer is outer hair cells can be seen near the center
of the basilar membrane where the hightest vibration takes place. The basilar membrane can be seen under the
inner hair cells, the movement of stereocilia and the resulting modulation
of their ionic currents is likely to be greater for outer hair cells than for
inner hair cells.
