Q

We have 60 uL digested DNA solution and 4X blue dye DNA loading buffer. In order to run DNA gel, we need to add a certain volume of 4X blue dye DNA loading buffer into DNA solution to obtain a final mixed solution with IX blue dye. Please calculate how much volume of 4X blue dye DNA loading buffer which you need to take and add it into DNA solution

A

What do plasmids mean
Double-stranded circular DNA in bacteria used for transformations of foreign DNA into bacterial cells covalently closed
65
Are plasmids chromosomal molecules
No extrachromosomal DNA that's self-replicating
66
Vectors
used to carry exogenous DNA from somewhere else and insert it into a host cell
67
Plasmid vector
vectors where a plasmid is used to carry the exogenous DNA, so it's transformed into recombinant DNA and introduced back into the cell
68
Competent cells
capable of taking exogenous DNA and have it inserted into their cells via transformation
69
What is the purpose to use competent cells
capable of taking exogenous DNA and have it inserted into their cells through a transformation higher efficiency used to propagate and maintain cloned DNA in plasmids
70
Transformation
exogenous DNA is taken into the new bacteria replaces a section on the plasmid (Lac Z)
71
Major steps of a transformation
thaw competent cells mix 2 uL sample and 50 uL competent cells keep on ice for 30 min heat shock 35 sec ice 2 min add LB incubate on shaker at 37 degree C for 1 hour plate on agar plate using sterile beads incubate 37 degree C overnight
72
During transformation, which heat shock temperature is used
42 degree C
73
Why are heat shock time and temperature crucial
you don't want to destroy your DNA or your cell you want to heat it enough so that the DNA can enter the cell, but not too long that your bacteria cells begin to die heat shock allows the DNA to enter through the membrane
74
What is the purpose to use the appropriate antibiotic during the transformation procedure
antibiotic resistance transformed bacteria will be given an antibiotic resistance gene, so all non-transformed bacteria will die on the agar plate and the transformed bacteria will grow Amp plate for Amp resistance

What is the purpose of LyseBlue
color indicator that shows optimum buffer mixing prevents errors that lead to inefficient cell lysis and incomplete precipitation of SDS, genomic DNA, and cell debris
162
at is the purpose of RNaseA
removes RNA from genomic DNA
163
function of Buffer P2

164
function of Buffer N3

165
At what wavelength does the maximum absorption of UV light occur for DNA
260 nm
166
At what wavelength does the maximum absorption of UV light occur for proteins
280 nm
167
What is a ratio of OD 260 / OD 280 that is less than 1.8 indicative of in relation to DNA
protein contamination in your sample DNA
168
Do not allow the lysis reaction to proceed for more than 5 min after adding buffer p2. why
if you go longer than 5 min, then you'll have more chromosomal DNA and it'll begin to denature the plasmid keeping it below 5 min allows for the release of plasmid DNA from the cell

170
What is the function of QIA spin column
separates DNA we want from all of the waste and other parts that we don't want (cell debris, RNA, proteins, etc) PB helps it bind to the filter When spun, everything we don't want goes through the filter and DNA binds to the filter PE is the wash buffer and it cleans off waste from DNA Elution buffer brings the DNA through the filter

DNA gel electrophoresis
when you use a gel made from agarose to separate DNA molecules using an electric current
192
How does DNA gel electrophoresis work
agarose gel made from powder agarose and liquid buffer (TAE or TBE) placed in the gel chamber once solid, placed in the gel machine with the same liquid buffer (which is ion-rich) because phosphate groups on DNA have a net negative charge, DNA migrates to the anode (positive pole) pores in the agarose gel that are responsible for the way different sizes of DNA migrate through
193
What is the function of DNA ladders
goes in the 1st or last well contains different components of known different sizes when you run a gel, it looks like a ladder and can be used to compare your samples to
194
Ethidium bromide function
DNA stain that binds to DNA and absorbs UV light gives off orange visible light when placed on UV transilluminator
195
Which DNA fragments run fast and why
smaller fragments pores in the gel allow smaller fragments to get through easier than larger ones
196
DNA loading buffer
makes DNA denser than the electrophoresis buffer can also contain dyes so that you can see the DNA after running the gel it will make the sample sit at the bottom of the wells
197
UV transiluminator
gives off UV light on the gel after running so that you can see your fluorescently-dyed DNA
198
In gel electrophoresis, DNA fragments migrate to...
the anode (red) because the phosphate groups are negative on the DNA
199
function of TAE buffer
mixture of TRIS, EDTA, and glacial acetic acid TRIS - buffer that works between a pH of 7-9 EDTA - metal chelator that binds to metal ions that are a cofactor for DNase Glacial acetic acid - provides the proper ion concentration TAE should be used for separating large fragments, cloning, and DNA extraction from a gel allow nucleic acids to move through the agarose matrix
200
Function of EDTA in TAE buffer
metal chelator that binds to metal ions like magnesium, which are required cofactor for DNase activity

major pcr steps
denature - hot temp to separate DNA strands annealing - lower temp when primers attach to ssDNA elongation - when DNA polymerase creates 2nd strand
261
dna polymerase
enzymes that helps amplify dna uses ssdna as a template to make complementary strand needs a primer
262
what are dna primers and what do they do
made of RNA and DNA bases first 2 bases always RNA synthesized by primase anneals to the ssDNA to create a 3' OH group for DNA polymerase to begin working

DNA ligation
catalyzed by DNA ligase involves covalently bonding 2 broken DNA fragments / strands
309
DNA ligase
enzymes that catalyze forming bonds between 2 broken DNA fragments / strands
310
how to set up ligation reaction with Roche kits
add T4 DNa ligase, T4 DNA ligase buffer, water, vector DNA, and insert DNA to a tube ligase goes last let incubate at room temp for 15 min
311
T4 DNA ligase
catalyzes phosphodiester bonds between either blunt or sticky ends
312
T4 DNA ligase buffer
sets up binding conditions has ATP so ligase can function
313
What is the best ratio of backbone and insert
1:1
314
what does gel extraction mean
taking DNA fragments from the band cut from the gel run and purify it so that the fragments can be used in the future cut out band you want put in microcentrifuge rube add 1mL QG buffer dissolve by putting in hot water bath transfer to spin column and centrifuge discard flow through add QG buffer again and centrifuge and discard flow through add PE buffer and centrifuge and discard flow through spin empty change outside of column to a clean microcentrifuge tube and add EB buffer let sit before centrifuging again
315
function of QG buffer
solubility of agarose used to dissolve the agarose from the gel helps with binding to the column membrane contains pH indicator (supposed to be yellow)
316
PE buffer
wash buffer to remove contaminants
317
EB buffer
elution buffer. anything bound to the membrane exits when spun down after using EB
318
what is the purpose of isopropanol
increases the yield of DNA fragments add to PE and helps as part of the wash buffer
319
purpose of pH indicator gel extraction
tells you if the pH is too high yellow = okay orange / darker color = pH too high
320
absorption of DNA to silica depends on pH. 95% when pH is
pH < 7.5
321
efficiency of DNA is dependent of pH. The maximum elution is achieved at pH
between 7.0 and 8.5
322
open reading frame
sequence of DNA that starts with the start codon and ends with a stop codon codes for a protein and is about 100 codon groups long
323
how to find open reading frame
find the start codon
324
what is the first amino acid residue of one orf
met (the start codon codes for it)
325
how does one orf stop after the last amino acid residue
when you reach stop codon tell ribosomes that they've reached the end and to release the polypeptide chain created from the orf
326
function of blast
compare your query sequence to sequenced dna from their online database important to compare because orf are conserved between proteins, so if your query sequence has an orf that's the same as another sample, you can use it to try to figure out the purpose of the protein coded from the orf (and shape and all that stuff)
327
major steps of pfu-mutagenesis
mutant strand synthesis DNP1 treatment to remove any parental plasmids transformation using IPTG and X-gal
328
function of DPN1 enzyme
remove parental plasmid present after PCR parental strands are methylated and new plasmids are unmethylated
329
