If primase makes an error and incorporates an incorrect base in the nucleic acid primer, then why would this not be a problem given the DNA replication mechanism? O Primase only copies end sequences that will be protected by telomers The lagging strand utilizes a helicase to prevent replication errors O Primase can be error proofed using a domain of DNA polymerase O The RNA primer sequence is removed and not used as a template

If a mutation occurred that prevented single stranded binding proteins from binding, the result would be: O Replication would not be initiated O DNA would be synthesized on the leading strand, but not the lagging strand Replicating would be initiated, DNA would unwind, RNA primers would be laid down, but DNA polymerase would not bind O The newly synthesized RNA would not be able to leave the DNA template Replication would be initiated, but RNA primers would not anneal to the DNA

Which statement is true about dna replication

Transverion mutations result from wobble type mispairing during DNA synthesis or replication spontaneous chemical lesions slippage of DNA polymerases during DNA synthesis or replication

Origin of replication [ Choose ] [Choose] Codon Complementary pairs with cytosine in a DNA molecule The site of protein synthesis Ribozyme This molecule can begin the synthesis of a polymer of nucleotides without a primer A short peice of lagging stand DNA Primase A reflection of redundancy in the genetic code RNA which exhibits enzymatic properties Okazaki Fragment The process of making RNA from DNA Helicase DNA polymerase Transcription Enzyme which lays down a segment of RNA on replicating DNA so that DNA nucleotides can polymerize A sequence of three nucletotides which codes for an amino acid Ribosome Point Mutation Chromosome Wobble Position The point on a stand of DNA where replication begins Mitochondria RNA polymerase [ Choose ] Guanine

Which of the following things must happen first if DNA is going to be replicated * DNA gets broken into smaller pieces to make the process more manageable DNA gets unzipped, so the two complimentary strands are separated DNA Polymerase adds on bases that match with the original strand DNA gets wound back into chromosomes so it's ready for mitosis Lenovo esc -> 女 # 2$ 2 3 5 6 7 8 9. tab e r t y a f k ift V alt ctri

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

Define DNA replication/synthesis and semiconservative replication.  In addition, describe and/or define the role(s) of each of the following in the process of DNA replication/synthesis: DNA template strand, 5’ and 3’ ends, DNA helicase, DNA polymerase, single-strand binding proteins, topoisomerase, primase, Okazaki fragments, leading strand and lagging strand.
