Briefly describe how ATP acts as an energy carrier in cells
What will be an ideal response?

Embryonic cell cycles allow the rapid division of cells in the early embryo. These mitotic cell cycles are much shorter in length than the mitotic cell cycles of cells in a mature organism. In the embryonic cell cycles, mitosis takes approximately the same amount of time as it does in the cell cycles of mature cells. What do you think is a result of the embryonic cycle? 32.

The movement of genetic material between organisms other than by descent is called ____
a. vertical gene transfer b. horizontal gene transfer c. parallel gene transfer d. sexual reproduction e. asexual reproduction
For a P1 transduction experiment, an E. coli donor strain with the genotype arg+, ser+, ampR and a recipient strain with the genotype arg-, ser-, ampS were used
The following results were obtained for each marker: Of the transductants selected for arginine, 5% are ser+ and 30% are ampR. Of the transductants selected for serine, 3% are arg+ and 0% are ampR. What is the correct order and relative distance of these three genes on the E. coli chromosome?
