You are characterizing a new dna polymerase. when the enzyme is incubated with [32p]dna and no dntps, you observe the release of [32p]dnmps. this release is prevented by adding unlabeled dntps. which of the following describes the reactions that most likely underlie these observations?

a)the dna polymerase contains 3'-5' and a 5'-3' exonucleases that degrade dna to produce [32p]dnmps.
b)the dna polymerase contains a 5'-3' exonuclease that degrades dna to produce [32p]dnmps.
c)the dna polymerase contains a 3'-5' exonuclease that degrades dna to produce [32p]dnmps.
d)any of the above could explain these observations.
e)none of the above.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.

The reactions that occur in the ribosome, where amino acids are combined to form proteins are anabolic or catabolic?

Amale bird-of-paradise uses a dance to attract mates in which it flaps its tail feathers on the ground and jumps around a potential female mate. a different male bird-of-paradise does a similar dance but it jumps around the female in the opposite direction. the female bird is only attracted to one style of dance, in one direction.
