DNA ligases cannot join the sticky ends of two DNA fragments. True False

Which of the following plays a role in repairing thymine dimers by reversing the damage caused by UV light exposure in bacteria? base excision repair photoreactivation enzyme postreplication repair non-homologous end-joining repair DNA polymerase proofreading

Which statement is true about dna replication

Draw out the molecular structure of a double stranded DNA molecule. This molecule is 6 bp in size. Don't forget label.

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

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

Which of the following DNA repair processes is known to be "error-prone" (i.e. resulting in incorporation of incorrect nucleotides as part of the repair process)? Mark all the answers that are correct. Base Excision Repair (BER) non-homologous end-joining of double-stranded DNA breaks. O Nucleotide Excision Repair (NER) post-replication repair SO-response

Which of the following is NOT true about Base Excision repair? Group of answer choices Ligase is responsible for resealing the nick in the phosphodiester backbone. Endonuclease is used to remove the damaged nucleotide. It is a preferred method of removal for larger defects in the genetic code Polymerase creates the new nucleotide to replace the damaged one Glycosylase removes damaged the damaged base before the nucleotide

Picture is only attached as reference. How does the model attached show DNA Replication?What is the importance of DNA Replication?What will happen if there will be an error during the DNA Replication Process?

The antiparallel nature of DNA ensures that identical RNA transcripts will be produced regardless of which strand of DNA is used as the template, so long as the transcript is synthesized 5' to 3'. True False
