In DNA replication, the fundamental reason that Okasaki fragments are produced is that Group of answer choices DNA replication can proceed only in the 5’ to 3’ direction replication on the leading strand is slower than replication on the lagging strand DNA polymerase tends to slip while replicating the lagging strand DNA polymerase has to alternate between the leading and lagging strands during replication none of these are true.

In comparing prokaryotic and eukaryotic replication, pick the one that in INCORRECT. Both have semiconservative replication Both strands made at same time by replisome consisting of helicase plus DNA pol holoenzyme Eukaryotes and prokaryotes both have leading and lagging strands RNA is only needed to initiate DNA synthesis in prokaryotes

As the strands are synthesized in replication, which of the following is true?   the leading strand is synthesized continuously from the 5' to 3' direction while the other strand is synthesized discontinuously in the 3' to 5' direction   both strands are synthesized  in the 5' to 3' direction   the strand that shows the Okazaki fragments is synthesized in the 3'-5' direction.   both strands are synthesized continuously

Which statement is true about dna replication

Semi-discontinuous replication means that:     DNA synthesis only occurs in the same direction as the replication fork.     the double helix unwinds and each strand serves as a template for a new DNA molecule.     there are Okazaki fragments associated with the leading strand.     DNA synthesis occurs in both a 5’ to 3’ and a 3’ to 5’ direction.     there is both a leading and a lagging strand associated with each replication fork.

Given the replication events listed below which even takes place first Single Strand binding proteins bind Primase adds an RNA primer Helicase unwinds the DNA double helix  DNA polymerase begins adding DNA nucleotides

Why do we find multiple, short RNA pieces inserted into the lagging DNA strand during DNA replication?   Question 43 options:   the DNA polymerase is replaced by the RNA polymerase in these regions for unknown reasons   the DNA polymerase doesn't copy flawless and adds sometime uracil instead of thymine to the growing daughter nucleotide strand   multiple RNA primers have been added with the help of the primase enzyme to create multiple start sites for  the DNA polymerase   Retroviruses sometimes like to insert their RNA into the replication fork and favor the lagging strand   multiple RNA pieces are most likely found in the leading not the lagging strand during DNA replication

1) Fill in the following replication bubble. Be sure to draw and label the origin of replication (both sides), the leading and lagging strands, & the 5' and 3' ends of alI DNA fragments. 5' 3'

Replication in eukaryotes begins at the OriC sequence. This particular sequence is characterized by (select the correct statements): A-T rich and therefore energetically more favourable to localy unwind DNA. Contains the DnaA boxes. Recruits histone acetyltransferases. Is locally unwound by DnaA, HU and IHF proteins. QUESTION 16 The Single Strand-binding proteins (SSBS) in prokaryotes and the Replication Protein A (RPA) in eukaryotes are functionally equivalent. Their role in the DNA replication process is to (select the correct statement): Stabilize the single stranded DNA structure after unwinding by the DNA helicase. Recruit the general transcription factors to the promoter. Relieve the torsional stress ahead of the replication fork. Induce double strand breaks. O O O O O O O

DNA replication in vivo requires a primer with a free 3' end. What molecule provides this 3' end? Group of answer choices DNA ligase DNA primer RNA primer Helicase None of these is correct
