what statement about the dna replication process in prokaryotes is true
Marlyn J.
Which of the following is NOT true regarding the initiation of DNA replication in bacteria? It involves a region of the DNA called oriC. All of the statements are true. The strands are initially separated at AT-rich regions of DNA. DnaA proteins bind to the DNA to begin separation of the strands. Following initial separation, DNA helicase enzymes continue to separate the strands. If DNA ligase is inhibited during DNA replication, what will be the consequence? Single-stranded nicks will be found throughout the genome. DNA polymerase III cannot replicate the DNA strands. RNA will be present in the newly replicated DNA. DNA strands will not remain single stranded for replication. DNA strands will not separate for replication. Which of the following statements is NOT a limitation of the DNA polymerases used for DNA replication? DNA polymerases cannot ligate sugar-phosphate backbones together. DNA polymerases can attach new nucleotides only in the 5' to 3' direction. DNA polymerases must begin synthesis using a primer or existing DNA strand. DNA polymerases must have a template strand to copy from. DNA polymerases can attach new nucleotides in the 3' to 5' direction only on the lagging strand.

The following statement about initiation of DNA replication is true: A) All chromosomes in both prokaryotes and eukaryotes have one origin of replication. B) Initiation of DNA replication occurs when an origin of replication melts. C) DNA polymerase initiates DNA replication by binding to an origin of replication, following by recruitment of DnaA or the ORC. D) DnaA is essential for initiation of DNA replication in all living cells.
