True or False? 454 platform sequencing involves attaching single -stranded DNA fragments to beads, which are embedded within a 96-well plate . The plate is exposed to separate washes of single nucleotides , which are used by DNA polymerase to synthesize complementary DNA. Each time a nucleotide is added, a pyrophosphate is released.

During agarose gel electrophoresis, why does DNA move through the gel when electric current is applied? because DNA is negatively charged because a charged chemical from the loading buffer is bound to the DNA because DNA is positively charged because DNA absorbs electricity
5'-[seq]-3' The diagram shows the results of gel electrophoresis for Sanger sequencing. The wells are represented by open boxes and the DNA bands are represented by black boxes. The wells are labeled to show which dideoxy reaction was loaded into each. Write the sequence of the original template strand used for this sequencing reaction, with the 5’ end on the left and the 3’ end on the right.
Similarities between DNA agarose gels and SDS-PAGE are: Both methods use agarose gels. Both methods use electrical charge differences to separate molecules by size. Both methods determine the size of DNA fragments. All the given answers.
Whether done manually or automated, DNA sequencing gels are always made of polyacrylamide rather than agarose. Why can't agarose be used for a sequencing gel, as it is for other DNA gel electrophoresis?
In Polymerase Chain Reaction (PCR), the temperature is one of the most important parameters that could influence the efficiency of this technique. Each cycle of this reaction has its own specific temperature. For instance, the denaturation step possesses a temperature of 94 - 98 ℃ to ensure that the double stranded DNA is fully separated. (i) (ii) (iii) Why is the annealing temperature vital in this technique? Explain how will this temperature affects the efficiency of this reaction. Why is Hot Start PCR technique preferred by some researchers? If the primers you purchased possessed the following information. 5'-GGA AAC AGC TAT GAC CAT G-3' Calculate the melting temperature of this primer and estimate the annealing temperature of this primer.
Questions are talking about amplification of DNA When we run the gel, we also run a ladder why? what information does that give us. why does it form a ladder shape on the gel (what is happening to cause things to separate out in many bands)?
Considering DNA sequencing by the Sanger method. It is correct to say that: * A)In the traditional method, radioactively “labeled” primers are used, allowing their visualization in autoradiography. B)In the automated method, a single reaction is performed containing the four “labeled” dideoxynucleotides, each with a different fluorophore. C)In both traditional and automated methods, the fragments are resolved and interpreted according to their ionization state. D)In the automated method, di-deoxynucleotides “labeled” with the same fluorophore are used, thus allowing their interpretation based on graphs of fluorescence emission. E)Sequencing reactions can use mRNA molecules, as long as they have a polyA tail.
1) What happened to the DNA at the different temperatures? How does Polymerase Chain Reaction exploit this property of DNA (Word count: 200) 2) Briefly outline the steps of DNA extraction as carried out in a lab for the purposes of sequencing, with reference to a published protocol from a company that supplies regents and kits for DNA extraction (e.g Qiagen, ThermoFischer, Invitrogen, or similar). Please Include the weblink for the published protocol you used as a reference
what type of gel(in terms of material) can be more suitable for the electrophoresis of 500-1000bp DNA fragment and why?
What is the role of GelRed® in Agarose gel electrophoresis of DNA fragments? GelRed® moves down the agarose gel in response to the electric current and enables visualisation of the position of the nucleic acids within in the agarose gel. GelRed® intercalates with the Nucleic acid and, under UV light, fluoresces to enable visualisation of the position of the nucleic acids in the agarose gel. GelRed® intercalates with the Nucleic acid and enables visualisation of the position of the nucleic acids in the agarose gel. GelRed® intercalates with the amino acids in the agarose gel and enables visualisation of the position of their in the agarose gel.
TRUE OR FALSE. a) The Sanger method of DNA sequencing follows the principle of complementarity just like in the replication process. b) Supercoiling whether positive or negative, can be experienced in the replication or transcription process.
Preparing plasmid DNA (double stranded, circular) for Sanger sequencing involves annealing a complementary, single-stranded oligonucleotide DNA primer to one strand of the plasmid template. This is routinely accomplished by heating the plasmid DNA and primer to 90°C and then slowly bringing the temperature down to 25°C. Why does this protocol work? What enzyme is used and what other components are required in the sequencing reaction? How does the Sanger method determine the sequence?
