- Binary fission in bacteria is beneficial for all of the following reasons EXCEPT: Group of answer choices Mutation rates in prokaryotes are high due to short generation times Prokaryotes can copy themselves in as little as 20 minutes, resulting in rapid population growth Prokaryotes can undergo rapid evolution due to the high mutation rates The daughter cells that are produced are genetically identical to the parent cellA bacterium undergoes four rounds of replication. How many cells would result, and how many of those cells would still have part of an original DNA strand from the starting bacterium?A region of DNA has six copies of a trinucleotide repeat. During one round of replication, the template strand slips as shown in the diagram. How many repeats will the DNA have if the newly synthesized strand is used as a template in the next round of replication? 1 5'-CAG 3'-GTC GTC 4 2 GTCH 3 2 CAG CAG GTC 3 GTC 5 4 CAG-3' GTC -5' 6 Next round of DNA replication
