Which of the following is not true about the termination of replication in bacteria?
Group of answer choices
Termination occurs at sequences called Ter sites.
Binding of Tus proteins to Ter sites blocks the advance of the replication fork by interacting with DnaB helicase.
There are two clusters of Ter sites oriented in opposite directions.
Replication forks can proceed past both Tus-Ter clusters, which causes problems when it runs into RNA polymerase head first.
Wrong statement: Replication forks can proceed past both Tus-Ter clusters, which causes problems when it runs into RNA polymerase head first.
Replication fork proceeds past the Tus-Ter cluster oriented towards the right while it stops in the cluster oriented towards the left.

Allows for an easier break of HydrUGLIO 5. Describe the role of each of the following in bacterial DNA replication: DnaA, DnaB, topoisom single-stranded binding proteins, DnaG, DNA polymerase III, DNA polymerase I, DNA ligase. recruit helicase proteins • DnaA: proteins bind to each other and the DnaA boxes • DnaB: (helicases) move in a 5' to 3' direction and unzip the double helix Topoisomerase: catalyze controlled cleavage and rejoining of DNA that prevents over-winding relieves torsional tension single-stranded binding...
In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....

Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...
AS Part A Which of the following events occurs during DNA replication? All methylation of the DNA is lost at the first round of replication Methylated DNA is copied in the cytoplasm, and unmethylated DNA is copied in the nucleus Methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where ane strand...
