Question 4 A student sees a smeary band of DNA at the top of their gel and thinks it might be
genomic/chromosomal DNA Amower saved contamination in their mini-prep. What is the most
likely cause of genomic DNA contamination? Mark a. Forgetting to lyse the cells during the
mini-prep b. Not placing the cels in the hot water bath for a long enough time c. Not being
careful to use sterile technique d. The student likely, forgot to wear gloves when loading the gel
and contaminated it with their own DNA. e. Vortexing after the lysis step so that the genomic
DNA is broken into smaller pleces that are extracted with the plasmid Ouestion 5 Aniwer shved
Minked ont of 100 r Miag question Select all that are true about plasmid DNA. a. Plasmids are
contained in the nucleus b. The DNA in plasmids is single stranded. c. Plasmids are much larger
than genomic DNA. d. Plasmids are muth smaller than genomic DNA. e. Plasmids are found in
the cytoplasm 1. Plasmids are an organelle found in bocteria 9. Human cells have many plasmids
that give us an evolutionary advantage. h. Plasmids often carry genes that give bacteria an
advantoge in certain situations.
