Based on what you have learned with respect to various DNA repair pathways, decide the most appropriate pathway that would be used to repair the following types of DNA damage. Explain your reasoning. A change in the DNA sequence caused by a mistake made by DNA polymerase during replication In a fungal species, pyrimidine dimers induced as a result of UV exposure A double-stranded break that occurs during G1 and prevents completion of DNA replication
Discuss DNA replication of prokaryotes and please mention all of the enzymes and components listed below. DNA Primase – DNA directed “RNA Pol” which inserts nucleoside triphosphates (NTPs) Primers are oligonucleotides; priming process is the formation of primers DNA Helicase – separates the DNA in advance of the replication fork (in E. coli DNA Helicase II); binds at AT-rich region of DNA; ATP then binds the helicase Single-stranded DNA-binding Protein (SSBP) – no enzymatic activity; does not consume ATP Topoisomerase – alter the supercoiling of double-stranded DNA DNA Ligase – nicking of strands done for replication to continue Okazaki fragments DNA Polymerase – removes primer via 5’ to 3’ exonuclease activity; comes again for 5’ to 3’ polymerization activity (closes the gap between Okazaki fragments) Prokaryotes DNA Pol I – auxiliary enzyme to DNA Pol III; repairs damage; capable of excising pyrimidine dimers; polymerization via single active site that can bind all 4 dNTPs;…
Assume a deletion occurs in a gene that encodes DNA polymerase I and no functional DNA polymerase I is produced. What will be the most likely consequence of this mutation? The DNA would not exist in a supercoiled state. There would be no RNA primers laid down. The DNA will not be able to unwind to initiate replication. The DNA strands would contain pieces of RNA. There would be no DNA replication on the leading or lagging strands.
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.
Below is a diagram of DNA replication as currently believed to occur in E. coli. Arrows start from numbers and end at specific points. Answer the questions relating to the locations specified by the numbers (1) Which end (5' or 3') of the molecule is here? (2) Which enzyme is probably functioning here to deal with supercoils in the DNA? (3) Which enzyme is probably functioning here to unwind the DNA?
During DNA replication, the function of RNA primers is to Group of answer choices serve as a binding site for DNA ligase separate the two strands of the double helix to open replication "bubbles" serve as starting points for DNA strand elongation by DNA polymerase in the 3' - 5' direction prevent new-separated strands of DNA from rejoining serve as starting points for DNA strand elongation in the 5' - 3' direction by DNA polymerase
Describe, in detail, causes for mutations that occur during replication. For each, use detail to describe how the mutation would occur, classify the type of mutation that results, and the effect it may have on the cell. What are two causes for mutations during replication? What is one cause for mutations at the end of replication? Differentiate between transition and transversion mutations. What are they, examples? How do point deletions/insertions lead to frameshift mutations- your answer should include what a “frame” is, what a codon is and how codons are responsible for making aa chains?
DNA polymerase occasionally incorporates the wrong nucleotide during DNA replication. If left unrepaired, the base-pair mismatch that results will lead to mutation in the next replication. As part of a template strand, the incorporated wrong base will direct the incorporation of a base complementary to itself, so the bases on both strands of the DNA at that position will now be different from what they were before the mismatch event. The MER-minus strain of yeast does not have a functional mismatch excision repair system, but it has normal base excision repair and nucleotide excision repair systems. Which of the following statements is correct about differences in the mutation spectrum between MER-minus and wildtype yeast? More than one answer is correct. Options: More point mutations will arise in MER-minus yeast. Fewer point mutations will arise in MER-minus yeast as compared with wildtype. Of the total point mutations that…

In relation to central dogma of molecular biology answer the following questions: A- Give two reasons why the DNA replication is asymmetrical process (i.e. the DNA replication outcome is different between the leading and lagging strands)? B-The following segment of DNA is part of the transcription unit of a gene. You know already that RNA polymerase moves in a specific direction along this piece of DNA to convert one of the DNA strands into a single strand RNA transcript so that this entire region of DNA is made into RNA. 5′-GGCATGGCAATATTGTAGTA-3′ 3′-CCGTACCGTTATAACATCAT-5′ Given this information, a student claims that the RNA produced from this DNA is: 3′-GGCATGGCAATATTGTAGTA-5′ Give two reasons why this answer is incorrect.
