2. The eclipse phase occurs in transformation because: A. Only single-stranded DNA can bind to receptors on recipient cells. B. Recipient cells are competent for only a short period of time and are in the eclipse phase the rest of the time. C. Uptake of transforming DNA by recipient cells involves degradation of one strand of the DNA. D. Most competent cells are capable of taking up virtually any DNA from the medium but only homologous DNA can take part in the recombination required to complete the process of transformation.

The eclipse phase is a period during the bacterial growth cycle when the cells are not yet dividing, and the newly synthesized DNA is not yet visible under the microscope. Show more…

When a cell in G1 phase is fused with a cell in S phase, the nuclei from the G1 phase cell immediately begins to replicate its DNA. In contrast, when a G2 phase cell is fused with an S phase cell, the nuclei from the G2 phase cell does not replicate its DNA. A) What cellular mechanism accounts for the differences in DNA replication potential between G1 phase and G2 phase cells? B) Describe the differences in genomic DNA and/or the proteins bound to genomic DNA between G1 and G2 phase cells that causes the different DNA replication potentials; AND state why these differences lead to different DNA replication potentials.
