WebCheckpoints of cell-cycle control system ensure that: A. the environment is favorable for the cell to initiate DNA replication. B. M phase is completed before cytokinesis begins. C. all chromosomes are attached to the mitotic spindle before the chromosomes are segregated to the two daughter cells. D. all DNA is replicated before M phase begins. WebSome other proteins and enzymes, in addition the main ones above, are needed to keep DNA replication running smoothly. One is a protein called the sliding clamp, which holds DNA polymerase III molecules in place as they synthesize DNA.The sliding clamp is a …

I hope this helps ( ╹ ╹ )
Web1) Initiation. After RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point on the template strand. 2) Elongation. The polymerase moves downstream, unwinding the DNA and elongating the RNA transcripts 5' --> 3'. In the wake of transcription, the DNA strands re-form a double helix. WebQuestion: what is one of the ways that mitosis and meiosis are different? a. pairing of homologous chromosomes occurs only in mitosis b. recombination (crossing over) occurs only in mitosis c.
