These are written as either accurate or contain errors. Rewrite each one with an error as an accurate statement. Please have an explanation. Thank you! Over time telomeres shorten over time because when the primer is removed at the end of chromosome strand cannot be filled in because there is not free 3’ OH. Semiconservative DNA replication indicates that daughter strands are hybrid molecules with half (one strand being parental) and the other being newly synthesized. A mutation in the gene responsible for transcribing primase would affect only the lagging strand of DNA. In eukaryotes RNA polymerase binds to the activator, specifically at the TATA box to align with the translational start site. Transcription Factors can have more than one function domain. One is the DNA-binding domain and the other is a trans-activation domain. Additive alleles function at one gene to contribute to the phenotype of an organisms, while non-additive alleles at that one gene do not add to the phenotype.…

Below is a picture of a single origin of replication in a eukaryotic cell. 5' 3' 5' 1. On the figure above, Draw out where the following molecules will be located: Helicase; Sliding Clamp, Single Strand Binding Protein. 2. On the right hand side of the dotted line, the replication of which template strand (top or bottom) will be continuous by DNA polymerase? 3. On the left hand side of the dotted line, the complete replication of which template strand (top or bottom) will be more affected by a mutation that causes DNA ligase to be partially functional?
1c) During DNA replication, both positive and negative supercoiling is introduced in the DNA being replicated. Name the enzymes that introduce supercoiling into DNA during replication; please clearly indicate which enzyme(s) introduce positive supercoiling and which enzyme(s) introduce negative supercoiling.
Why is the company Qiagen has more refined DNA extraction steps than a normal Strawberry DNA extraction practical? Summary of Qiagen DNA extraction steps Add ATL buffer and grind with sample. Add 20 microliters of enzyme Proteinase K to degrade protein into a 1.5-2ml microcentrifuge tube. Add 200 microlitres AL lysis buffer, and mix by vortexing for 5–10 seconds, which breaks cell membrane allowing DNA to be released. Incubate the sample at 56 degrees for 10 minutes. Mix the cell lysate with 200 microlitres ethanol by pipetting it at the side of the microcentrifuge wall so DNA precipitates. The DNA forms a white layer and the remaining liquid is discarded. Pipet the mixture into DNeasy Mini spin column placed in a 2 ml collection tube. Centrifuge for a minute at 8000 rpm. Place the mini spin column into a 2 ml collection tube, add 500 µl Buffer AW1, and centrifuge for 1 min at 8000 rpm. Then add it to a new 2 ml collection tube (provided), add 500 µl Buffer AW1, and centrifuge for 1…
